Everything that flies, drives or ships gets shaken \u2014 by a launch, a runway, a road or an engine bay \u2014 and whatever is going to rattle loose, crack or fail is going to do it there, in service, where it’s expensive and sometimes catastrophic. Neometrix’s vibration & shock test system brings that environment into the lab, turns it up, and finds the weakness on the shaker instead of in the field. It’s an electrodynamic shaker with amplifier and closed-loop controller, slip table and head expander, running random, sine, shock and shock-response-spectrum profiles to MIL-STD-810, IEC 60068 and ECSS \u2014 with a combined vibration-plus-climatic option for HALT\/HASS testing.<\/p>\n
A launch or a truck ride shakes a product across a whole frequency spectrum at once, not as one clean, swept tone. A real test has to reproduce that measured spectrum \u2014 a power spectral density profile \u2014 under closed-loop control, rather than the simplified single-frequency sweep that used to pass for a vibration test. That distinction is the core of what actually makes a qualification test valid.<\/p>\n
The shaker and amplifier are the muscle. The vibration controller \u2014 closing the loop against accelerometers to match the reference spectrum and hold the level \u2014 is the brain. Get the control loop wrong and you either over-test (breaking a genuinely good unit) or under-test (passing a genuinely bad one). Both failure modes defeat the entire purpose of qualification testing.<\/p>\n
The specimen has to see the true motion the test intends to deliver; a poorly designed fixture adds its own resonances and distorts the result \u2014 either inventing a failure that would never happen in the real world, or masking one that would. Slip tables, head expanders and rigid, characterised fixtures are part of the core engineering here, not an afterthought bolted on after the shaker is chosen.<\/p>\n
Vibration and shock is the dynamics member of the same environmental-qualification family as Neometrix’s climatic chambers, EMI\/EMC laboratory and thermal-vacuum chamber \u2014 temperature, electromagnetics, space and now dynamics, together forming the full qualification suite a serious test facility needs.<\/p>\n
Mount the shaker to a climatic chamber and you get vibration at temperature \u2014 HALT\/HASS \u2014 which precipitates failures that neither vibration testing nor temperature testing alone will ever find. The combined configuration is a distinct, genuinely valuable test capability, not a marketing bundle of two separate machines.<\/p>\n
The electrodynamic shaker, amplifier and controller are bought-in specialist equipment. Neometrix engineers the system around them: the seismic-mass foundation, slip table, head expander, fixtures, the combined climatic option, safety and controls. No specific delivered system is claimed on this page \u2014 this describes a reference configuration engineered to order.<\/p>\n
