摘　　要：本文用多体系统动力学理论建立了由Ｎ个物体组成的多体系统中任意一个物体具有位移和速度约束时的振动解法，推导了相应的计算公式，并形成了计算机程序，用质量弹簧系统力学模型检验本文方法的正确性和通用性。All mechanical systems exist constraints, constrainting the motions of body, When a body in a mechanical systen moves along a trail ,the mechanical system exists the displacement and velocity constraint. This paper presents the solution of mechanical system with the displacement and velocity constraints ,and deduces its calculative formulas. To use mechanical model with masses and springs checks the correctness and general characteristic of the solution pressented by this paper.
