正弦波

The process of shock acted on a vibration and shock isolation system with double-stiffness was divided into two steps. In the shock action phase of a half sine wave, the response was calculated by using a double DOF model. In the free vibration phase, the response was calculated by adopting a single DOF system, the initial displacement and velocity of single DOF adopt the final value of the first phase.
