The invention belongs to the technical field of mechanical design and manufacture, and discloses a method and device for matching spokes and rims of wheels of passenger cars. The method comprises thefollowing steps of establishing a 3D parametric model of a wheel rim based on the parameter information of the spoke and the rim of the wheel; establishing the parameter database of matching material;obtaining a stress-strain cloud diagram of the wheel steel rim under the load condition based on the 3D parametric model of the wheel steel rim and the parameter library; based on the stress-strain nephogram, obtaining fatigue life nephograms of various matching materials corresponding to spokes and rims of wheel rims through fatigue life model calculation. The method provided by the invention can realize the combination matching of the spokes and the rim of the wheel steel rim wheel and the theoretical prediction of the fatigue life through the reasonable structural modeling and the materialparameterization, optimize
