Abstract：The structure strength and protection performance of the vehicle sound for pedestrians are the important technical indexes of the design of the structure system. In this paper, the structure, material selection and seal design of a vehicle sound for pedestrians are analyzed, and the structural strength and protective performance indexes of the product are also discussed. Through the analysis of the mechanical simulation design, it is demonstrated that the strength of the system meets the design requirements of the product. Through the selection of the product parts and the design of the sealing structure, the system protection level is IP67, and the protection performance of the system also meets the requirements of the product design.
Key words：vehicle sound for pedestrians；structural strength；protective performance；mechanical simulation
