Development of Sectional Steel-Aluminum Material City Bus Body

Abstract

In order to solve the contradiction of city bus of steel body with large mass and aluminum body with high cost, the city bus body which middle body was built with aluminum and others with steel was proposed.Five kinds of aluminum alloy sections and connectors were designed to construct the bus body. The initial thickness of sections were identified. The suspension model was built by beam and spring element. The modal characteristics, statics stiffness and strength of steel-aluminum skeleton under the bending-torsional coupling operation condition were analyzed based on opti Structs software. The results indicate that low order intrinsic frequency of steel-aluminum skeleton has little change compared with steel skeleton, but modal shape has a greater difference. When the static strength meets the yield strength of material, the mass is 971. 2 kg which is decreased by 146. 8 kg compared with steel bus body.
