Calculation Method For Coupled Vibration Between Tooth Contact And Nonlinear Structural Components Under Running Conditions

The purpose of this study was to develop a numerical calculation method for gear system vibration, which changes depending on nonlinear structural components such as bearing clearance and spline contact. The numerical calculation method uses multibody dynamics simulation with the following features: a) the use of theoretical tooth shapes and stiffness to represent the tooth contact of gear pairs, b) the use of finite element models to express the gear system, including the nonlinear structural components causing the variation, c) consideration of the coupled vibration between the tooth contact and gear system. The numerical calculation method allowed the prediction of the variation tendency due to changes in some clearances and spline contacts.
