| Abstract: | By using random signal and vibration analysis system CRAS4.1 edition, modal experiment and analysis were carried out with hammer hiting on main parts of LD480 Diesel Engine, the former 5 ranks (or geater than 5 ranks) mode parameters and vibration models were obtained. By identifying mode parameters of the frame, foundation can be provided for dynamic analysis and improving design of main parts of LD480 Diesel Engine. |
