Optimum design method of non-bearing frame structure of light vehicle

The invention provides an optimum design method of a non-bearing frame structure of a light vehicle. The optimum design method comprises the steps of establishing a three-dimensional geometrical model of the original frame structure of the light vehicle by use of SolidWorks software and outputting the model in the IGES (Initial Graphics Exchange Specification) data file format, thereby obtaining the IGES model of the frame structure, next, reading the IGES model of the frame structure in Hypermesh software, performing geometrical processing and dividing finite element meshes by use of the Hypermesh software, and performing topological optimization on the cross beam structure of the frame by use of the structure optimization function of the Hypermesh software without changing the structural forms of the longitudinal beam and the attached seats of the frame, thereby realizing the optimum design of the arrangement position and the structural form of the cross beam structure. The optimum design method of the non-bearing frame structure of the light vehicle is capable of improving the bending rigidity and torsional rigidity of the frame of the light vehicle and the inherent frequency of the frame structure without increasing the weight of the frame structure, thereby ensuring that the frame has relatively high overall rigidity and improving the reliability, security, operation stability and vibration property of the vehicle.
