摘要：
For the modeling and simulation of the torsional vibration of automotive driveline system, an identification method of torsional vibration excitation is proposed in this paper. Firstly, a real vehicle test is conducted to obtain the torsional vibration data of the sample vehicle during acceleration. Then, a 4-DOF nonlinear dynamic model is established for studying and predicting the torsional vibration characteristics of the sample vehicle. Meanwhile, a fitting function of the cylinder pressure curve is put forward, and an estimation of cylinder pressure curve is obtained through parameter identification, so the excitation torque is acquired. Next, a numerical simulation is performed on the model with its results compared with test data, verifying the correctness of the model. Finally, through the adjustment of the stiffness of clutch damper and the half shaft and the installation of an inertia plate on propeller shaft, the natural frequency of the driveline system is shifted beyond the commonly-used speeds, avoiding the resonation of torsional vibration. The results show that the function fitting-based cylinder pressure curve identification method can effectively identify the excitation of the torsional vibration of driveline system with high accuracy, providing theoretical support for the research on driveline torsional vibration. © 2022, Society of Automotive Engineers of China.
