Abstract

The power train modal is needed to pay attention because it is a main factor to affect vibration. The relationship between power train modal and connecting plane was studied in this paper. The global vertical connecting plane is the main factor to affect power train global bend mode#1, especially the connecting plane between clutch box and engine block. Build a simple approximate model, and find the key factors affect the power train global bend mode#1 with this model. The key factors include connect stiffness ‘K’, span distance ‘L’ and inertia ‘I’. Then do several testing and CAE analysis, validated some methods to improve connect stiffness and power train modal. At last, applied these conclusions to optimize the modal of a 4 strokes L4 engine and improved the natural frequency of power train global bend mode#1 from 198 to 254 Hz. This study has gotten some useful conclusions, and these conclusions can be used to optimize power train global bend mode effectively.
