Abstract: In view of the high accident rate of domestic road transport of dangerous goods, decen- tralized road transport vehicle standards, many design reference standards, and inconsistent understanding of standards, the paper first defines the applicable products that meet the paper based on the summary of design standards and design processes; Secondly, the tank design process of road transport tank semi-trailer for liquid dangerous goods is studied, and the design flow chart is established; Finally, according to the design flow chart, from the aspects of design input, design conditions, determination of design parameters, tank structure design and system design verification, the key points of tank design are emphatically discussed, and the design methods and precautions in the design process are introduced in detail, which effectively improves the design quality and efficiency of new products. The research has certain theoretical significance and engineering application value.
