摘　　要：针对汽车制动钳体在车削加工中的工艺要求,利用软件Pro/E设计了专用夹具的三维模型,并结合其机械仿真功能对模型进行了平衡性分析。研究结果表明,通过对车夹具三维建模设计与运动学仿真,可在样机制造之前预测车夹具的装配干涉及准确添加平衡铅块质量,以消除由车夹具不平衡质量所引起的加工颤振,提高了产品设计质量。Aiming at the technical requirements of brake caliper during the turning processing,a 3D model of the special fixture is established by using Pro/E,and the balance analysis is made on the model with the aid of Pro/E＇s mechanical simulation feature.The study shows that through the 3D modelling and kinematic simulation, it is able to forecast the assembly interference of fixture and add correct lead balance weight to eliminate the machnining chatter caused by unbalanced fixture weight befre propotyping,so as to improve product design quality.
