Summary:

AbstractPrediction of noise and vibration of a gear train is important to achieve a competitive design. Objective of this paper is to develop a dynamic simulation model for vibration analysis and a synthesis process to predict vehicle interior noise using TPA (Transfer Path Analysis). The hybrid gear model is developed to simulate the stiffness of teeth and meshing characteristics in a gear pair. It is modeled by using the teeth stiffness map which is following real contact characteristics of a gear pair. The teeth stiffness is obtained by structural analysis. The multi-body model is composed of flexible bodies, shafts and nonlinear bearings. Input forces at the mounting point (input point) of the gear train are calculated by accelerations from dynamic analysis under real operating conditions. Calculated forces are used to synthesize a vehicle interior noise. Predicted noise is compared with experiment data
