传统上，人们大多研究物体局部区域或简单结构间的接触问题及其详细力学性态；本文将接触问题放入机械系统中进行研究，不仅考虑物体间的接触，更关注机械系统中各物体的总体弹性变形与物体接触边界间的耦合影响。本文应用势能最小原理，建立了一类描述机械系统中多区域接触问题的力学模型，用一组代数方程组描述接触体间点的约束关系，获得一组包含力学模型和约束方程的代数方程组。用Ｎｅｗｔｏｎ－Ｒａｐｈｓｏｎ 法求解之，可获得系统中各物体的接触状态和接触边界的应力应变分布状态 Traditionally, people mostly study the contact problems between local and simple structures of objects and their detailed mechanical properties. In this paper, the contact problem is studied in the mechanical system, which not only considers the contact between objects but also focuses on the objects in the mechanical system The Influence of Coupling Between Overall Elastic Deformation and Object Contact Boundary. In this paper, by using the principle of minimum potential energy, a kind of mechanical model describing the multi-zone contact problem in a mechanical system is established. A set of algebraic equations are used to describe the constraints of the contact points. A set of algebraic equations including the mechanical model and the constraint equation . Using the Newton-Raphson method, the stress-strain distribution of contact states and contact boundaries for each object in the system can be obtained
