摘　　要：利用UG建立大型注射模数据模型,在建立运动仿真时常遇到解算时间长的问题,分析运动仿真中连杆与运动副、连接器的联系,得出结论:影响解算速度的是仿真中建立的3D接触数量及其中连杆的小平面数量。通过减少3D接触中连杆小平面数量或直接减少3D接触的数量,建立最优的运动仿真模型,以提升运动仿真模型的解算速度,达到提升工作效率的目的。The data model of large injection mould was established through UG software. The calculating time was very long when established the motion simulation. By analyzing the relation between connecting rod and kinematic pair, connector in the motion simulation, the conclusion was that： the influence factor for calculating speed was the number of 3D contact and the number of small planes of connecting rod in the simulation. Through reducing the number of both factors, the optimal motion simulation model was established to promote calculating speed of movement simulation model.
