【Abstract】 Techniques related to reliability analysis of gear vibration and wear are introduced,gear vibration excitation analysis and finite element simulation are carried out,and mesh stiffness of the time-varying gear is calculated analytically.A two-dimensional diagram of the gear is designed by software MATLAB,a three-dimensional model of the gear is generated by Creo,and the gear is analyzed and simulated by ANSYS to derive the reliability and sensitivity of random parameters on the transmission error of gear meshing vibration,which lays a foundation for the research of gear vibration and wear.更多还原
