Research on Running Ride Comfort of the Multifunctional Harvester

摘要

Based on the structural analysis of the multifunctional harvester, dynamical vibration equation with 5-degree of freedom is built by Lagrange method through rational simplification. Considering road surface random excitation drive and pulse excitation, simulation analysis of the running ride comfort is carried on to the complete machine model of vibration. Running ride comfort of the multifunctional harvester is predicted or evaluated, providing the basis for the design of adding the shock mitigation system to the multifunctional harvester.
