| Abstract: | In order to realize the lightweight design of automotive structural parts,plastic substitute steel and size optimization technology were used in the design of metal brake cylinder.OptiStruct was used to analyze the strength of the metal cylinder by refering to QC/T 200—2015 and the results were evaluated.According to the theoretical formula,the thickness of the new air cylinder made of lightweight plastic PA66 was estimated,and then the specific thickness of each component was obtained by using the size optimization method.The optimization results show that the new brake air storage cylinder can meet the requirements of the strength standard while reducing the mass by 56.5%. |
