What is shock response spectrum analysis?

A Shock Response Spectrum (SRS) is a graphical presentation of a transient acceleration pulse's potential to damage a structure. It plots the peak acceleration responses of a bank of single degree-of-freedom (SDOF) spring, mass damper systems all experiencing the same base-excitation as if on a rigid massless base.

What is shock analysis?

It calculates and defines how a single degree-of-freedom system with different hypothetical natural frequencies would respond to the shock. To illustrate how this is helpful, let's take that 50g, 10ms pulse and calculate how a system with a 30 Hz, 85 Hz, and 250 Hz natural frequency responds to that input.

How do you calculate response spectrum?

Understand that the method of determining response spectrum Sa=Sa(T) for a given diagram of accelerations F(t), where T refers to period, Sa refers to acceleration spectrum, t refers to time, while F(t) is a given time analysis function.

What is SRS vibration?

A Shock Response Spectrum (SRS) is a graphical representation of a shock, or any other transient acceleration input, in terms of how a Single Degree Of Freedom (SDOF) system (like a mass on a spring) would respond to that input.
