Abstract

Abstract: In order to realize the minimization of the drum washing machine, the feasibility of replacing the cast aluminum material with fiber-reinforced thermoplastic composite material for the pulley was analyzed through CAE simulation calculation. In the analysis process, PP+50% GF plastic was selected as the substitute material. After the preliminary structural design, finite element model establishment, and calculation boundary and working conditions were determined, the maximum deformation and stress were simulated and calculated, and the structural design was optimized according to the calculation results. The final calculation results show that the deformation and stress of the composite material pulley meet the standard requirements, and the weight reduction of 14.9% and cost reduction of 20% can be realized. The replacement is feasible.

Key words: Minimization, Fiber reinforced thermoplastic composites, Simulation analysis, Structural optimization
