摘　　要：通过对柴油机缸体的试验模态分析,得到缸体的模态频率和振型参数,并对前10阶模态振型的结果进行分析,根据试验结果,找出缸体的薄弱部位并为其结构的优化提供了实验依据。By applying modal testing to diesel engine, modal frequencies and vibration parameters are obtained and the first ten ranks modal parameters are analyzed. Based on testing data, the weak sections of the cylinder block are determined and all these experiment evidences are provided for the development of engine structure.
