Analysis on Dynamic Performance of Drive System Based on Riccati Transfer Matrix

建立了动力机械常用传动系统扭转振动的动力学模型以及数学模型,并引入R iccati传递矩阵对模型进行求解.通过模态柔度的计算,找出了系统的危险模态,并且通过对危险模态下能量分布率的计算,确定了系统的薄弱环节,为传动系统动态性能的优化提供了理论依据,为设计方案的修改指明了方向.

A dynamics model and its corresponding mathematics model of the drive system of the enging is set up, and the model is solved through using Riccati transmits matrix. A dangerous mode in torsional vibration is found through a calculation of flexible degree of modality,then the weak links of this system are confirmed through a calculation of distributing rate of energy under this dangerous mode,it offers a theoretic evidence for the optimizing design of the drive system and shows an improved direction for the project.
