Heavy-duty Commercial Vehicle Frame Based on the Bench Test

This paper analyzed the force of the frame of heavy commercial vehicles in motion,expounded the frame bench test methods,and through the use of the frame of the bench test analysis bending stress,deformation and fatigue,as well as torsional stiffness and fatigue. It achieves validation purposes of the reliability of the frame structure,and provides an effective basis for the design of to meet the requirements of strength and rigidity of the frame.
