What is the shock response spectrum test?

— Part 4 Compare to pendulum SRS tester, why choose pneumatic shock response spectrum test system?

The disadvantages of the pendulum shock response spectrum tester:

1) The free fall of the pendulum produces limited excitation energy. If a larger shock energy is required, the mass of the pendulum and the radius of the pendulum need to be increased, which not only consumes a large amount of power of the geared motor and clutch, but also takes up a large space, needs special safety protection;

2) For the simulation of higher energy shock response spectrum, the shock energy realization method cannot meet the requirements;

3) Most of the existing pendulum shock response spectrum testing machines use electromagnetic clutches to pull in the pendulum shaft to prevent the pendulum from rebounding again. The clutch is subject to shock loads and is easily damaged and worn;

4) The adjustment of the back seat support cushion of some pendulum shock response spectrum testing machines is very cumbersome, and the manual thread adjustment method has poor consistency and low efficiency.
