摘要
将试验模态分析技术应用于4113柴油机的动态分析 通过对4113柴油机气缸体组件的试验模态分析,得到气缸体组件的模态频率和振型参数,并对前6阶模态振型的结果进行分析 根据试验结果。
Method of experimental modal analysis is introduced and the dynamic analysis is applied to 4113 diesel engine. By applying modal testing to 4113 diesel engine, modal frequencies and vibration parameters are obtained and the first six ranks modal parameters are analyzed. Based on testing data, the weak sections of the cylinder block assembly are determined and some suggestions for the structure optimization are proposed.
