Time has become the major role in the market competition, so the directintegration of reverse engineering and rapid prototyping is becoming important more and more.
随着市场竞争的不断加剧,时间因素占据着主导地位,反求工程和快速成型技术的直接集成越来越受到重视。

It is found that the displacement input model is more accurate than the generally used acceleration input model, given the same directintegration method and time step.
By means of the precise time-integration method and the method of directintegration of state equation, the mode of the time-integration has been discussed on the structural dynamical responses.
