VIBRATION ANALYSIS OF DYNAMIC MODELLING OF GEAR PAIR IN MESH DUE TO TORQUE AND LOAD ON THE SYSTEM

Abstract

This paper presents dynamics modeling of gear pair in mesh. State space analysis and MATLAB operation are used to obtain natural frequencies and graphs of motion on the system. Torque load are applied to analysis numerical integration solution. The results are compared to the one without torque and load. The torque acts on pinion and the load acts on gear output. The natural frequencies of the gear pair in mesh system are calculated from the complex eigenvalues. The graphs of the gear angular velocity show that in star-up region, angular velocity increases with its rate velocity. It was vibrates with various amplitude. In steady state region, the gear angular has a constant average value. Applying the mesh stiffness variation affects in the changes of wave form and amplitude of the gear velocity vibration. The variable value of mesh stiffness causes vibration of the gear pair in mesh system. In addition, transmission error of the gear pair in mesh system tends to go into a constant value after periodically change. It is still vibrates in the gear system with the mesh stiffness variation.
