Vibration Testing Laboratory in Southern California
As specialists in dynamic testing, we provide equipment capable of exerting a 6,000 to 18,000 pound force with the capacity to perform closed-loop control from a single input to multiple channel inputs (from 2 to 32) with averaging or notched channel control. Vibration control systems can be programmed for real time monitoring, scheduled for length of time, or level scaled by dB or percentage, or scaled at various durations at different acceleration levels.
We have electro-dynamic shakers at 2-inch stroke and servo-dynamic shakers at 4-inch stroke with a range of capabilities. Most of our electro-dynamic shakers are attached with slip-plates to perform multi-axis testing.
We regularly perform vibration testing to MIL-STD-810, RTCA DO-160, MIL-STD-750, MIL-STD-202, as well as ISTA, EN, IEC, and ASTM specifications. We also provide unique tests like Gunfire, Transportation Packaging and NAVMAT screening. .
When called upon, we provide specialized environments that include Temperature, Humidity, Rapid Temperature Change, Salt Spray and Combination Environments with our vibration tests that can be supervised 24/7 with on-site monitoring or remote monitoring.
The key to developing a great test plan is having vibration fixtures that are non-resonance, controllable configurations, manufactured from aluminum or magnesium materials that hold single or multiple parts for test. Many times, we stock pre-configured expansion heads and plates that can be easily incorporated to your test article, which will lower your fixture cost and accelerate your time to test. Each fixture is tested for performance and tuned to perform at its best. Let us help with your fixture designs and manufacturing needs.
Real-time performance assessment (Vehicle or Machine Vibration Data) can be provided by our systems technicians by instrumenting your product with accelerometers, thermal couples, stress and strain devices, measurements on test tracks, or machinery for improved testing in the lab. As an engineer, you need to know what you are designing for and the conditions for use so you don’t under or over test your product. Having this information is also important for your FEA design staff to determine stress input.
MIL-S-901D Lightweight Shock Testing in Southern California at Environment Associates
Environment Associates performs high impact mechanical shock which applies to equipment, machinery, systems and structures mounted on ships . The purpose of these requirements is to verify the ability of shipboard installations to withstand shock loadings which may be incurred during wartime service due to the effects of nuclear or conventional weapons. We also perform vibration per MIL-STD-167 for mechanical vibration of shipboard equipment to complement our shock testing services.
