Shock Response Spectrum (SRS) Test System

A Shock Response Spectrum (SRS) is a graphical presentation of a transient acceleration pulse’s potential to damage a structure. The horizontal axis shows the natural frequency of a hypothetical Single Degree Of Freedom (SDOF), and the vertical axis shows the peak acceleration which this SDOF would undergo as a consequence of the shock input. 

A shock response spectrum is a useful tool for estimating the damage potential of a shock pulse, as well as for test level specification.

The shock response spectrum is a calculated function based on the acceleration time history. It applies an acceleration time history as an excitation to an array of single-degree-of-freedom (SDOF) systems. Each system is assumed to have no mass-loading effect on the base input.

PVSRS Pneumatic Vertical
Shock Response Spectrum Test System

  • PVSRS series pneumatic shock response spectrum tester is used to measure and determine the shock resistance of electrical and electronic products or packaging, and to evaluate the reliability and structural integrity of the test product in a shock environment. The shock response spectrum is the total result of a series of single-degree-of-freedom linear systems with different natural frequencies subjected to the same shock excitation response. When a product is subjected to an impact, the maximum value of its impact response means that the product has a maximum stress. Therefore, the shock response spectrum tester can better simulate the shock wave and shock energy suffered in the real environment.
