Abstract

The microcultivator is a widely used agricultural machinery in hilly and mountainous areas in China. The intense vibration generated at the handrail during the cultivation process poses a health risk to operators. In this study, the IWGQ4-70 microcultivator was selected as the research object, and a particle damping absorber design method for the microcultivator handrail was proposed. The vibration characteristics of handrail are investigated by finite element method, and the energy dissipation mechanism of particle damping absorber is analyzed by discrete element method. A test platform was designed and constructed to validate the simulated results. Particle material, particle size, filling rate and other parameters affecting the vibration damping performance of particle damping absorbers were selected and verified in actual working condition tests. The results showed a good correspondence between the experiments and simulations, and the optimized solution achieved the expected effect, with a vibration reduction effect of 58.8% and significant damping effect.
