摘　　要：应用有限段法的基本思想建立了具有弹性连杆机构的多刚体-弹簧-铰链系统离散化模型,再利用建立多刚体系统动力学方程的矩阵方法导出了离散化模型的非线性系统动力学方程。数值计算结果与有限元法的结果的一致性,说明了本方法的有效和简便。Based on the idea of Finite Segment Method,the multirigid-spring-hinge system models for plane mechanisms with elastical connecting rods are presented.Then the nonlinear dynamic equations of the system are derived according to the method of multirigid-body dynamics.A numerical example shows that the method is effective and rather simple.
