摘　　要：根据与广西玉柴机器股份有限公司合作项目的要求,对曲轴-飞轮组合进行试验模态分析获取其固有频率、振型和阻尼,对建立的模型进行有限元模态分析,将计算结果与试验结果对比分析。通过有限元模态分析与模态测试结果的对比,验证了有限元模态分析模型与结果合理性。According to the cooperation project with Guangxi Yuchai Machinery Co., Ltd., an experimental modal analysis was carried out to obtained the natural frequency, mode shape and damping of the crankshaft-flywheel combo in this article. The article analyzed the established model by using the finite element method, finished the contrast analysis between the calculation results and test results,By contrast finite element modal analysis and modal test results to verify the finite element model and modal analysis results rationality.
