The finite element design crane car group

Bridge crane car by lifting mechanism, operation mechanism and frame of 3 parts, maximum weight of 40 t. Frame should meet the requirements of strength and stiffness, the traditional calculation method of the simplified ChengLiang car frame unit, due to the complexity of the constraint, the calculation results and the actual condition of the beam element has a certain discrepancy, this paper using ANSYS software to establish the whole model of the car frame, to deal effectively with its constraints, load, crane trolley car lifting mechanism block and tackle applied load bearing box calculation results of finite element analysis plate finite element model
