摘　　要：曲轴是发动机最为重要的部件,主要计算分析了曲轴的静态和动态性能,并利用试验优化技术对曲轴进行了改进设计和多种方案的试验比较,得到了试验指标下的最优解,为今后的曲轴设计提供了一些科学依据和可行性方案。Crankshaft is the most important element of engine; therefore, a static and dynamic performance analysis of a crankshaft is conducted to provide necessary information for design improvement. Based on the analysis result and by experimental optimization, modification to previous crankshaft design and comparison testing of various modification schemes are made. As a result, an optimal solution of the crankshaft design by the test index is obtained, which serves as a scientific basis and feasible scheme for further crankshaft design.
