Assemble Simulation is widely used in the practice of machine desigrL How to simulate a component in a complex assemble efficiently and accurately attracts the attention of many researchers. Based on sub-model method and force analysis method, component isolator method in assemble simulation is proposed. The method can be described as following：, an entire assemble is meshed moderately and simulated firstly, and then the focused component is isolated, whose relation with the surroundings is substituted by boundary condition and nodal displacem...
