Optimization design and structural analysis of hydraulic elevating mechanism based on ADAMS and ANSYS

A virtual prototype model of bridge inspecting vehicle is set up by using ADAMS and ANSYS,which working processes is analyzed through ADAMS virtual prototype simulation to find out the most dangerous working condition.Then the hinge location of the hydraulic cylinder for elevating is optimized taking the smallest pulling force as object to determine the design variables by sensitivity analysis.The optimization results show that the maximum pull decreases by 21.1%.Afterwards load values of the related hinge points are read at the initial time through ADAMS and the supporting structures are changed according to the position of the hinge point.Finally the statics Finite Element Analysis for the overturning platform is done in ANSYS,which result of indicates that stress and deformation decrease largely after optimizing,the bearing load of overturning platform is improved and validity of the optimum design is verified.
