Abstract:Aiming at the problem of leg-upturning of the crane with 500t full-ground H-leg in certain working condi-tions, the simplified finite element model is built for the chassis structure, to study the effect of stiffness of frame and leg on leg upturning amount, and work out such effect rule, hence to provide certain reference for reasonable design of crane's chassis structure.
