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.

HALT TESTING IN SOUTHERN CALIFORNIA
Environment Associates provides the services of accelerated testing for determining a component’s limit of operation or a system’s risk hierarchy for failure modes. EA can develop a test plan for a component, product or system that will activate potential failure modes that could cause premature warranty claims or diminish the value of your company’s brand. As an industry leader in accelerated testing, we can develop a test plan to include the type of expected service conditions for mechanical cycling, environment, electrical stress, contaminations and human unexpected use. These stress sources can be engineered into sequential singular stress tests or multiple stress environments.
EA includes thermal cyclic testing with high performance ramp rates in combination with random vibration testing as a key component for HALT and HASS testing. These two combined stress sources could be sufficient for a circuit board only test; but to reveal a product’s full set of potential failure modes, a product test must include all significant stress sources in combination with vibration and temperature. For example, a weak hinge on a plastic cover that remains in a stationary position may never show weakness if only temperature and vibration are applied, but if it is mechanically cycled while subjected to temperature and vibration, key information may be found. When you think about it, how many products do you use every day that have a singular stress? The answer is none. So we need to test with real world, combined stress sources to find real world results.
Our HALT/HASS chamber can provide 200°C to –100°C temperatures with ramp rates that can exceed 60 c/minute. We can provide vibration at 50 Grms from 10 Hz to 5 KHz. This Screening Systems chamber is best for traditional, Highly-Accelerated Life Testing (HALT) and Highly Accelerated Stress Screening (HASS) applications.
Key Benefits:
* Reduced Warranty Claims
* Quick comparison for product maturity for cost reduction changes
* Reduction in engineering development time and testing
* Rapid discovery of potential design flaws
* Testing that coincides with engineering FEA models
