It is necessary for the designers to calculate the impacting force by using impacting amplified spectra.

The shock amplification factor and shock response properties of the radiogram were obtained.

Signal recovery of structural responses to undex and shock spectrum computation;

Objective An analysis and measurement system was developed for use with shock spectrum testing machine for testing spaceflight products.

The vertical impact loads on the engine mounting are calculated based on the shock spectrum formulations, provided by the German Military Specification BV043/85 and the related literatures, besides temporal signal method is adopted to calculate the anti-shock ability of the mounting.

The Shock Spectra of Washing Machine under the Action of Half-Sinusoid Pulse;

The shock spectra and the damage boundary curve of corrugated board under the action of half-sinusoid pulse are obtained using four steps of Runge-Kutta numeric method, and the influence of various factors on shock response is discussed.

Based on the nonlinear dynamical equation of product packaging system,the shock spectra and the damage boundary curve of tangent nonlinear packaging system under the action of half-sinusoid pulse are obtained using a numerical method,and the influence of various factors on shock response is discussed.

The usual way to calculate the residual shock response spectrum of the base shock response is as follows: the time domain shock response of the base is calculated firstly, then the residual shock response spectrum of the base response is calculated.
