Natural frequency optimization and structure redesign of a bicycle splash shield are completed with the combination of reverse engineering and topology optimization. Based on reverse engineering, the three-dimensional model of the splash shield is established. The maximum first natural frequency is taken as the design objective, the maximum acceleration response and minimum volume are taken as constraints, and the material density is taken as design variable. The variable density method is used to realize the optimization of the splash shield. The results show that: the first natural frequency increased by about 5 times under all constraints after optimization; the combination of optimization design and reverse engineering technology is an effective method of structural design.
