Abstract

To study the vibration characteristics of loader gearbox, based on the theory of elasticity, the time-varying meshing stiffness of each level of gear pair is calculated using analytical method. Establish a finite element model for the dynamic contact of gear pairs at all levels, and simulate and analyze the dynamic meshing force of the gear pair during the meshing process. Establish a multi body dynamic finite element model of the gearbox gear transmission system, obtain the vibration modes and corresponding frequencies of the gearbox and the box through modal analysis, and compare them with the excitation frequency to determine that the system will not resonate; Taking the dynamic meshing force of each level of gear pair as the load condition, the modal superposition method is used to calculate the vibration response of the system. The peak value of the frequency domain response mainly occurs at the meshing frequency and its doubling frequency of the gear pair.
