Overview

Find the weak point here, not in the field.

Everything that flies, drives or ships gets shaken — by a launch, a runway, a road or an engine bay — and things that are going to rattle loose, crack or fail do it there, in service, where it is expensive and sometimes catastrophic. A vibration & shock test system brings that environment into the lab, turns it up, and finds the weakness on the shaker instead.

Real environments are random, not neat sines. A launch or a truck ride shakes a product across a whole spectrum at once, so the test reproduces that measured spectrum — a power-spectral-density (PSD) profile — under closed-loop control, rather than one swept tone. That is the core of a real qualification.

It is a control problem as much as a power problem. The shaker and amplifier are the muscle; the vibration controller, closing the loop against accelerometers to match the reference and hold the level — without over-testing (which breaks a good unit) or under-testing (which passes a bad one) — is the brain.

The fixture can lie. The specimen must see the true motion; a poor fixture adds its own resonances and distorts the result. Slip tables, head expanders and rigid fixtures are part of the engineering, not an afterthought.

The field is an honest, expensive examiner. The shaker asks the same questions first — louder, faster, and where a failure costs a re-test, not a mission.

The Dynamics Leg of the Family

The environment, completed

Vibration & shock is the dynamics member of the same environmental-qualification family as our climatic chambers, EMI/EMC laboratory and thermal-vacuum chamber — temperature, electromagnetics, space and now dynamics, the full qualification suite.

Combined Environments

What single tests miss

Mount the shaker to a climatic chamber and you get vibration at temperature (HALT/HASS) — which precipitates failures neither vibration nor temperature finds alone. The combined system is a distinct, valuable configuration.

Honest on Sourcing

We integrate; the shaker is specialist

The shaker, amplifier and controller are bought-in; Neometrix engineers the system — seismic-mass foundation, slip table, head expander, fixtures, the combined climatic option, safety and controls. No delivered system is claimed on this page.

Architecture

Drive, shake, control.

The schematic follows the drive chain — reference, controller, amplifier, shaker, specimen — and the accelerometer feedback that closes the loop, with the detail panel listing the test types it runs.

The Drive Chain

A reference profile (a random PSD, a sine sweep or a shock pulse) into a closed-loop vibration controller, a power amplifier, and an electrodynamic shaker that produces force to ~100 kN — the specialist, bought-in heart of the system.

Arc · 02

Specimen, Fixtures & Axes

The specimen on a head expander for the vertical axis or a horizontal slip table for the horizontal axes, on rigid, characterised fixtures — so it sees the true motion and the fixture does not add resonances of its own.

Arc · 03

Closed-Loop Control

Accelerometers on the table and specimen feed the controller, which matches the reference spectrum and holds the level — the closed loop that prevents over-testing a good unit or under-testing a bad one, and measures the response across the specimen.

Arc · 04

Combined & Controlled

Coupled to a climatic chamber for vibration + temperature/humidity (HALT/HASS), on a seismic-mass foundation with interlocks and safety — running automated profiles to MIL-STD-810, IEC 60068 and ECSS, and logging every test.

Specifications

Reference system, sized to your specimen.

The parameters below describe a reference vibration & shock test system. The shaker force, the slip-table size, the fixtures, the combined climatic option and the controller channels follow from the specimen mass, the test levels and the standard — a bench shaker to a 100 kN class system.

Where vibration testing goes wrong

In the control and the fixture, not the raw force. A controller that cannot hold the reference spectrum over-tests in one band and under-tests in another — failing good hardware and passing bad; a fixture with its own resonance injects motion the specimen would never see and invents a failure, or hides a real one; a specimen with too few response accelerometers is tested blind, with no proof the level actually reached where it matters.

That is why the loop is closed, calibrated and logged, the fixtures are designed and characterised, and the response is measured across the specimen. A vibration test is only worth the fidelity of the environment it claims to reproduce.

Variants

One principle, four systems.

Tenders call it a vibration test system, an electrodynamic shaker, a shock test machine or a HALT/HASS chamber. The principle — reproduce the environment, control it honestly — is common to all.

Var · 01

Electrodynamic Vibration System

The reference system — shaker, amplifier and closed-loop controller for random, sine and shock on the vertical axis, sized to the specimen mass and the test levels.

Var · 02

Slip Table & Head Expander

The horizontal slip table and vertical head expander with fixtures — the three-axis capability and the fixturing that lets a real specimen be excited faithfully.

Var · 03

Combined Vibration + Climatic

The shaker coupled to a climatic chamber for HALT/HASS — vibration at temperature and humidity, to precipitate the failures that combined stress reveals.

Var · 04

Shock & SRS System

Classical shock and shock-response-spectrum capability — with pneumatic or free-fall shock where high-amplitude, short-duration pulses beyond the shaker are required.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 Why random vibration — isn’t a swept sine enough?

Because the real world is random, and a sine is not. When a product rides a rocket, a truck or an engine bay, it is shaken at many frequencies at once, continuously, with energy spread across a broad band — that is what a random vibration test reproduces, by controlling the whole spectrum to a defined power-spectral-density (PSD) profile that matches the measured environment. A swept sine, by contrast, puts all its energy at one frequency at a time as it sweeps; it is excellent for finding resonances and for specific fatigue cases, but it does not represent a broadband service environment and can badly over- or under-stress a product compared with what it will really see. Serious qualification standards — MIL-STD-810, IEC 60068, ECSS — are built around random testing for exactly this reason, usually with sine used alongside for resonance search and specific sine environments. A real system does both, under closed-loop control, and the important engineering is reproducing the right spectrum, not just making the table move.

Q · 02 You say it’s a control problem — what do you mean?

The shaker can produce enormous force, but force alone is not a test — the value is in delivering exactly the specified motion at the specimen, and that is a closed-loop control problem. A vibration controller sends a drive signal to the amplifier and shaker, reads the actual motion back from accelerometers on the table and specimen, and continuously corrects the drive so the measured spectrum matches the reference — many times a second. Get that loop right and the specimen sees precisely the environment the standard calls for; get it wrong and the system over-tests in some frequency bands (breaking hardware that would have survived) and under-tests in others (passing hardware that would have failed) — both of which invalidate the qualification. This is why the controller, the accelerometer channels and the fixture characterisation matter as much as the shaker’s force rating, and why we treat the measurement and control chain as core engineering rather than an accessory to the machine.

Q · 03 Why do the slip table, head expander and fixtures matter so much?

Because they decide whether the specimen actually feels the test you think you are running. A bare shaker drives one point on its vertical axis; to test a real product you need to excite it on all three axes and to mount it rigidly. A head expander enlarges the vertical table so a bigger specimen can be mounted; a horizontal slip table — a plate on an oil-film bearing driven by the shaker through a coupling — carries the specimen for the two horizontal axes. Between the specimen and the table sits a fixture, and this is where tests are quietly won or lost: a good fixture is rigid and transmits the table’s motion faithfully up into its own high-frequency range, while a poor one has resonances of its own that amplify or attenuate the motion, so the specimen sees something quite different from the reference — inventing a failure that is not real, or masking one that is. Designing and characterising fixtures, slip tables and head expanders is a large part of what makes a vibration system trustworthy, and it is exactly the integration engineering Neometrix provides around the bought-in shaker.

Q · 04 What is HALT / HASS, and why combine vibration with a climatic chamber?

Because stresses combine in service, and combining them in test finds failures that single stresses miss. HALT (Highly Accelerated Life Test) and HASS (Highly Accelerated Stress Screen) apply vibration and temperature together — and often rapid thermal cycling — to a product, deliberately beyond its normal limits, to precipitate latent weaknesses quickly. A joint that holds at room temperature can loosen when thermal expansion and vibration act together; a solder crack that stays closed cold can open hot under vibration. To do this, the electrodynamic shaker is coupled to a climatic chamber, so the specimen is vibrated while it is taken hot and cold and humid, and the response is watched for the failure. It is a distinct and valuable configuration: HALT during design finds the weak links to fix, and HASS in production screens out latent defects before shipment. It is also a natural fit for us, because we build the climatic chambers as well as integrating the shaker — the two halves of a combined-environment system come from the same house.

Q · 05 How is this different from a chassis dynamometer or a shock-arrestor test facility?

Different machines for different jobs, despite some shared words. A chassis dynamometer holds a whole vehicle with its wheels on rollers and simulates road load — it measures power, emissions and drive-cycle behaviour, not the broadband vibration environment of a component. A snubber or shock-arrestor test facility tests hydraulic dampers — the snubbers and shock arrestors used on pipework and structures — by stroking them and measuring their damping force; it is a hydraulic-mechanical test of a damper, not an electrodynamic reproduction of a vibration spectrum. A vibration & shock test system does neither: it uses an electrodynamic shaker to subject a component or assembly to a controlled random, sine or shock environment for qualification to MIL-STD-810, IEC 60068 or ECSS. We build all three — the chassis dynamometer, the snubber test facility and this — and they are separate products; if your requirement uses a word like “shock” or “dynamic test”, we will confirm which of them you actually need before quoting.

Q · 06 Do you build the shaker, or integrate a bought-in one?

We integrate a bought-in shaker into a complete, engineered system — and we are clear about the split. The electrodynamic shaker, the power amplifier and the vibration controller are proprietary specialist instruments from established makers, chosen for the force rating, frequency range and the standard. What Neometrix designs and delivers is everything that turns them into a working test facility: the seismic-mass foundation that isolates the shaker’s reaction from the building, the slip table and head expander, the test fixtures and their characterisation, the optional combined climatic chamber, the safety, interlocks and controls, and the installation, commissioning and acceptance. It draws on the same test-laboratory integration competence behind our climatic and environmental chambers, our EMI/EMC laboratory and our thermal-vacuum chamber — of which this is the dynamics member. To be plain about status: this capability is offered turnkey and quoted against vibration and shock test-system requirements; no specific delivered system is claimed on this page.
