【正文】 ement of the wheel, according to the technology requirement. At the same time refer to other small displacement vehicle wheel, then design four new wheel, through CATIA software to acplish the modeling. Use CATIA to analysis the model and analysis the four wheel, include strength analysis 、 modal analysis, to calculator every wheel’s stress distribution、 natural frequency、 vibration patterns, pare with the result, with the fitness of the basic performance, choose the structure to design a more reasonable wheel design project. The analysis result indicated that, The conclusion obtains which after the finite element analysis basically tallies with the actual situation, also design proposal one and design proposal four spokes structures more reasonable, the spoke structure stress is even also far is smaller than uses the material the allowable stress, conforms to the design requirement This subject research work can use as a refer for the research and development for the Al wheel. evaluat ion of scient if ic developm ent .
