Optimization of Vehicle Drivetrain Torsional Vibration Characteristics Based on Sensitivity Analysis

Abstract

Abstract:

By using partial derivative method, the sensitivity formula of natural frequency and vibration mode shape to moment of inertia and stiffness in non-damping free torsional vibration system of a vehicle drivetrain were worked out. Based on the sensitivity formula, sensitivity value of natural frequency and vibration mode shape of a vehicle drivetrain torsional vibration system to structure parameters were calculated and the most sensitive structure parameters were obtained. By modifying these parameters, natural frequency and vibration mode shape of drivetrain were optimizated and torsional vibration became weaken. The study can provide a proof for the dynamics performance optimization of automotive power train.

Key words: torsional vibration, natural frequency, vibration mode shape, sensitivity, dynamics modification

摘要：

利用偏导数法分析得出汽车动力传动系无阻尼自由扭振固有频率和振型对转动惯量和扭转刚度的灵敏度。以某车型动力传动系扭振特性为例，通过分析固有频率和振型对转动惯量和扭转刚度的灵敏度，找出对固有频率和振型影响最灵敏的结构参数，对其进行动力学修改，实现传动系固有频率和振型的优化，从而减轻扭振的程度。研究成果可为汽车传动系的动态特性优化提供依据。
