| Abstract: | 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. |
