Abstract

The shock characteristics of a hyperbolic tangent nonlinear packaging system with critical component were investigated under the action of half-sine acceleration pulse. The dynamical model of the system was developed, and the numerical results of the dynamical equations were got. Based on the results,the three-dimensional shock response sprctrum of critical component was obtained.And the effect of the pulse duration, the frequency ratio, the dmaping ratio,the pulse peak acceleration in addition to the defined system parameter on the maximum shock response acceleration of critical component was discussed.It’s shown that all of their effects are noticeable.

Key words

Critical component / nonlinear / double-degree-of-freedom / three-dimensional shock sprctrum
