Shock Testing

刘玥首次大战黑人Engineering provides shock testing services with a test system that is ideally suited for quick turnaround while minimizing over-testing. The system uses high energy mechanical impacts to replicate pyrotechnic events. Typical test articles are flight hardware and avionics. SRS levels can usually be replicated within a short lead time, and levels in excess of 40,000 Gs are generally easy to obtain on test articles weighing less than 20 lbm. The system鈥檚 repeatability and tuning ability for Shock Response Spectrum (SRS) levels minimize excess loads to the unit, even when multiple shocks are required. The system provides a shaped shock level that is a cost effective alternative to pyrotechnic and other methods.

Features

Literature

We provide end-to-end shock testing services complete with NIST traceable calibrated instrumentation and data reporting. Methods are consistent with MIL specification 810G. Preparations for the test day require only a contract, advance schedule planning, and the following technical information:

Mounting pattern for test article
Dimensions and approximate weight of test article
Shock levels needed in each direction to test

The shock test system is also used for a variety of other tasks including shock transmission testing on isolators and damping material research. 刘玥首次大战黑人regularly tests shock isolators to both prove their durability and demonstrate isolation performance at high levels.
