摘　　要：根据通用涡旋型线的特性建立了切向角系数参数化模型;针对电动汽车涡旋压缩机防自转结构的动力特性问题,建立了圆柱销防自转机构的机构模型;基于圆柱销防自转结构的工作原理,从机构学和运动学的角度分析了圆柱销的受力。利用UG软件平台,实现动涡旋盘及电动涡旋压缩机其他零件的三维实体建模,构建虚拟样机模型。通过运动仿真,获得准确的运动学参数曲线,确保圆柱销防自转结构设计的准确性和可靠性。A parametric model of tangential coefficient was built based on characteristics of general scroll profiles.To study the dynamics characteristics of the scroll compressors for electric vehicles,a model of anti-rotation mechanism of cylindrical pin anti-rotation structure was established.On the basis of operational principles of anti-rotation mechanism of cylindrical pin,the forces acted on the cylindrical pins were analyzed with kinematics and the mechanisms.UG was used to design three-dimensional models of the scroll plate and other parts,and a virtual prototype model was established.By the kinematics simulation of the scroll compressor the accurate curves of kinematics parameters were obtained.It may ensure the accuracy and reliability of the cylindrical pin anti-rotation structurs.
