This study focuses on the design and optimization of the body of a new aluminum alloy truck,aiming to reduce wind resistance and improve the fuel efficiency and transportation performance of the truck by improving the body structure.In order to solve the problem of large wind resistance of the traditional truck body at high speed,this paper proposes a new type of truck body design based on aluminum alloy material and arc structure.Wind tunnel experiments and computational fluid dynamics(CFD)simulations are used to verify the effect of reducing the drag coefficient of the design at different speeds.The experimental results show that the use of the new car block can significantly reduce the drag coefficient by about 22.5%,and then improve the fuel efficiency by about 10% .In addition,the structural stability,material properties and durability of the new aluminum alloy body are analyzed,and the significant advantages of aluminum alloy in terms of light weight,corrosion resistance and service life are pointed out.The research results provide a new direction for the design of the truck body,which is helpful to improve the overall performance of the freight vehicle.
