Abstract: Aiming at the problem of the variable load and working conditions for pull arm system of detachable garbage truck, oil cylinder lifting force, pull arm force and pull arm changing rules of stress and strain in the packing and discharging were studied.Based on the rigidflexible coupling analysis method,the rigidflexible coupling simulation system that the pull arm was regarded as flexible body was established by using the mechanical system dynamics software ADAMS and finite element analysis software ANSYS,and the joint simulation was done,so the force of pull arm system at different pull arm angles and lifting angles and the position of the maximum stress and strain were obtained, and the strength and stiffness of pull arm assembly body were verified to meet the design requirements.The results indicate that rigidflexible coupling simulation can effectively simulate the force of pull arm system,and can more accurately determine the dangerous condition of pull arm system comparing with the method of typical working condition because of considering the dynamic load effects on strength analysis,which provides a reliable reference for structure optimization of pull arm system.
