According to the different design sizes of bicycle wheel, spokes and wheel, this paper discusses the deformation mechanics characteristics of the impact block, and analyzes the size of the wheel, the spokes and the hub combination have the smallest deformation. In this paper, the finite element analysis software is used to make the bicycle wheel frame impacted by the 40km/hr of the rigid body (mass of 200 grams) to observe its deformation and stress distribution. This paper also uses the Taguchi method to find the design parameters that can achieve the minimum deformation, select the wheel diameter, the hub radius, the number of spokes, and the spokes angle as the main control factor, respectively, for the simulation evaluation and discussion of the wheel frame with the same/different volume of the original design. The results of this case study show that under the optimal combined conditions, the deformation of the original design 1.328mm can be reduced 5.57% under different volume, and if the optimal design parameters under the same volume as the original design are further considered, the deformation can be reduced 1.13%. Then, the maximum stress value is less than the material yield strength.
