三轮农用运输车动力传动系扭转振动的研究

Study on Torsional Vibration of Power Train of a Farm Fransport Vehicle

对三轮农用运输车的动力传动系扭转振动进行了试验研究 ,分析了发动机扭转激励。

A power train of farm transport vehicle is a multi degree torsional vibration system. In this work, the authors experimentally researched the torsional vibration characteristics of the power train in a farm transport vehicle. The influences of engine and road excitations on torsional vibration characteristics of a power train and the coupled the torsional vibration of power train and the whole vibration were analyzed. Some suggestions on improving the torsional vibration characteristics of power train were proposed.
