Gear Drive System Simulation of Input Parameters Effect on Rattle

摘要

The understanding of gear dynamics is essential to design the power transmission with low vibration and noise radiation level. The virtual prototype is proposed for transmission dynamic investigation. This article deals with investigation of input parameters effect on gear rattle. The rattle noise is caused by hitting the tooth by each other, which can be noticed by vibrations evaluation on the gearbox housing. The evaluation is done by surface normal velocity comparison, which is connected to the emitted noise. The simulation results show that the torque and backlash has influence on the tooth contact loosening at the starting of rotation.
