Vibration testing, on the other hand, determines the extent to which items can withstand mechanical vibrations. Mechanical Shock Testing. Mechanical shock testing typically involves subjecting a test device to sudden and extreme amounts of acceleration or deceleration while instrumentation, such as strain gages, load cells, piezo sensors and more.
Vibration Testing Shock and vibration testing is used in a number of ways to help manufacturers gain insights on product reliability. During testing, the type of vibration stresses used are selected to mirror the typical expected vibration that the product may see during transit, and throughout its life-cycle.

ATS’ vibration testing services are administered to meet vibration qualification and safety compliance requirements. Our vibration capabilities test for structural integrity, resonance search and dwell, shock, drop and tumble, and seismic testing.
In contrast, for more robust vibration testing, random vibration testing subjects specimens to unpredictable and random rates of vibration — like an automobile running over a potholed road’s surface or a boat’s hull being struck by a series of rogue waves. Vibration Testing
Sine Vibration Testing. Sine vibration testing applies a single frequency to a test item and selectively excites resonant structures within the device. In a swept sine test a vibration sine tone is ramped up and down through a range of frequencies and for a specified rate and duration.
Vibration and mechanical shock testing helps attune automotive products for structural soundness and paramount vehicle perception using methods such as resonant searches and dwells, fixture resonance evaluation, custom fixture design and fabrication, reproduction of sample road and/or event data, shock response spectrum (SRS) testing, and more.

The benefits of vibration screening Vibration remains one of the earliest indicators of a machine’s health Vibration can identify problems before other symptoms, including heat, sound, electrical consump-tion, and lubricant impurities. More than half of unplanned downtime is attributed to …
conditions. Testing the product to failure will teach the company many important things about its product’s weaknesses and ways to improve it. Random testing is the key testing method for this kind of application. Random vibration is also more realistic than sinusoidal vibration testing, because random simultaneously includes all the forcing
Vibration Testing Rocket boosters and spacecraft are subject to intense acoustic environments during launch, which induce high levels of vibration in structural elements and equipment. In addition, elastic structural interactions with propulsion systems and flight control systems can produce low-frequency, high-deflection flight instabilities.
Shaker Vibration Testing. Quality is the watchword of modern manufacturers and testing feedback is the way they achieve it. Vibration testing on electrodynamic or hydraulic vertical shakers (and on shaker-driven horizontal slip tables) is done for a broad range of reasons.
A statement of the vibration emission (or a statement that the vibration test has produced a vibration emission of less than 2.5 m/s 2) together with information on the test method used. For most types of tool, manufacturers use internationally agreed test methods for vibration testing.
Environmental stress screening, also commonly referred to as temperature-controlled testing, or ‘shake and bake’, is a form of testing where products are subjected to high or low temperatures or to cyclical temperature fluctuation, while being shaken, to ensure that the combination of thermal and vibration stress does not cause the product to fail.
Vibration testing is a method of testing to ensure that products meet durability, performance, and most importantly, safety standards. Real world conditions cause vibration. The three areas of vibration are structure born, fluid born, and air born. Within these three …
May 09, 2018· Vibration analyzers typically require advanced training, third-party experts, or are too expensive to use on most equipment, leaving significant gaps in maintenance programs.
