摘　　要：对某V8发动机曲轴进行运动学分析与动力学分析,利用Pro/Engineer软件建立三维模型,然后根据有限元理论,应用ANSYS软件分析了曲轴的静态力学性能。分析第一左缸与第三右缸爆发时的应力云图和变形图,从结果可以看出,曲轴的应力集中在轴颈与曲柄臂连接处、油孔处以及连杆轴颈中央截面处。For some V8 engine crankshaft, kinematic analysis and dynamics analysis is presented. With the help of Pro/E software, the three dimensional model is established. Based on the finite element theory, with the application of software ANSYS, the static analysis of the crankshaft is gained, and the mechanical properties are obtained. For the first left cylinder and the third right cylinder at break, the analysis of stress cloud and deformation graph are obtained. Simulation results show that the stress concentration of the crankshaft emerges on the shaft neck and crank arm joint, oil hole and connecting rod shaft neck in the central section.
