Multi-Body System Dynamics Modeling of a Locomotive for its In-Service Parameter Effects Prediction

Abstract:

To understand the nature of train dynamics to its in-service parameter effects during high operational speeds, multi-body system (MBS) modeling of a Chinese locomotive SS₉ was performed. Following comparison of the field test data with the simulation result shows that they agree with each other with considerable accuracy, thus, the MBS model established is validated and being effective for further dynamics studies. For demonstration, a case study was conducted and demonstrates that with the increase of effective series stiffness, the hydraulic yaw damper could dissipate the lateral vibration energy of the front bogie significantly.
