How to perform different shock waveforms testing

DATE: 2022-11-07 VIEW COUNT: 149

Shock testing is applicable to assess the shock resistance of products or packaging, and to evaluate the reliability and structural integrity of products in a shock environment. 

There are three conventional shock waveforms:

- Half-sine wave

- Post-peak sawtooth wave

- Trapezoid wave

The half-sine wave generator is mainly made of engineering rubber (considering the stiffness and cohesive force of rubber) and felt pads of various thicknesses.Different thicknesses are overlaid to form multiple stiffnesses to achieve different shock pulse widths; trapezoidal wave generator air source is high-pressure nitrogen, the pressure range is 1-10MPa, and the overload value can be adjusted between 10-100g.
