SRS Pyroshock testing is commonly used to determine a test article’s ability to tolerate the mechanical stress waves produced by a high frequency, high-G shock event, such as rocket stage separations. SRS pyroshock specs are found in most aerospace hardware test procedures, given as a graph profile showing “response” acceleration (g) on the Y-axis and frequency (Hz) on the X-axis. The Y-axis acceleration values represent the profiled g-level measured by a set of analysis filters that have a specified gain, or Q factor (Q = 10 typical).
Experior Laboratories uses Unholtz-Dickie T-2000 vibration systems optimized for high G shaker shock up to 5,000 G. Unholtz-Dickie vibration systems have inductively coupled solid metal coil armatures to prevent driver coil failure. Shakers with 3” stroke and 180 in/s of velocity allow for high G shock tests with large displacement requirements or short transients.

with levels up to 5000 G on the T2000 Shakers,
making Experior Labs the industry leader in
SRS Shaker Shock.
Adjustable resonance allows us to boost acceleration in only the desired frequency range. For shocks with a specified Te (event duration), adjustable muzzle velocity, impact mass, and custom damping materials allow us to customize shock duration while meeting acceleration requirements.
The KIPS system boasts short transients, narrow differences between positive and negative SRS traces, and a uniform shock input that allows for near-equal measurements at multiple fixture mounting points. We’ve designed a wide variety of custom shock platforms and fixtures using frequency analysis software to identify mode shapes and resonant frequencies, which lets us prevent cross-axis acceleration and ensure that units are not over-tested.
