| 摘 要： | 根据发动机悬置软垫的工作环境及橡胶材料的力学特性,将空间问题简化成平面问题。针对传统有限元方法和边界元方法模拟裂纹沿任意方向扩展存在的不足,应用新型数值模拟方法-无网格局部彼得洛夫-迦辽金方法,一种纯无网格法,对具有初始裂纹的发动机悬置软垫进行了断裂模拟,得到了裂纹的轨迹。

| Abstract: | According to the working environment of engine suspension pad and the mechanical properties of rubber,simplify the space problem into plane problem.Aiming at the insufficiency of traditional finite element method and boundary method in simulating crack propagation in arbitrary direction,it used a new numerical method which is called meshless local Petrov-Galerkin method,a truly meshless method to simulate the fracture behavior of engine suspension pad with initial crack,and obtained the trajectory of the cr... |
