Study on the torsional vibration properties of 4102BZQ diesel engine crankshaft |
| |
| Abstract: | This study constructs the equivalent system model of 4102BZQ diesel engine crankshaft, and investigates the torsional vibration modes of the crankshaft which is free - free suspended. The natural frequencies and mode shapes of 4102BZQ diesel engine crankshaft are determined by the Holtz method and compared with experimental data from torsional vibration testing. The accuracy and validity of the analytical approaches are verified.The results show that the Holtz method is more effective method to conduct the modal analysis of crankshaft. |
