Simulation Vibration in the Automotive Powertrain
Vibration of the Automotive powertrain system affects not only the efficiency of the powertrain but also the noise-vibration-harshness (NVH) quality of the overall vehicle. In some severe cases, parts of the powertrain can be damaged by the excessive stress caused by vibration and particular resonance.
This paper presents a simulation result of modeling vibration of the powertrain system. The model takes into account of the static and dynamic force from the engine, from the clutch, from the transmission and active wheels. Using finite element methods (FEM), the harmonic responses of the powertrain in different loading scenarios are analyzed. From the numerical simulation results, references for several methods will be proposed to optimize the performance of the powertrain system.
