In this paper, an improved dynamic substructures method is described. The problem of torsional vibration of diesel complex shafting is analysed with this new method.
本文给出了一种改进的动态子结构法，并用该方法分析内燃机复杂轴系扭转振动问题。
Nonlinear dynamic model of total automobile system was established by mixed substructure component model synthesis which contains some soft substructures.
采用包含软子结构的间接对接的混合界面子结构模态综合法，建立了整车系统非线性动力学模型。
Another advantage of the method is that the order of the reduced dynamic equations will not be controlled by degrees of freedom on interface, because there is not any interface between substructures.
此方法的另一个优点在于它是无界面的子结构，动力方程的缩减不受界面目由度的控制。
