| Abstract: | By using AVL/ EXCITE-PU and ABAQUS software,and based on multi-body dynamics of the crankshaft,the WP7 diesel engine was simulated and counter-force of the bearing shell in the main bearing seat was calculated.At the same time,according to the comparison of calculation results and torsional vibration test data,the finite element model's validation and calibration were accomplished,and thus got the main excitation data of body structure noise.Furthermore,through dynamics simulation,it was concluded that the ... |
