Characteristics of the overall dimensions of two-axle trucks in China and the determination of representative vehicle parameters

Abstract

To clarify the distribution characteristics of the external dimensions of two-axle trucks in the current market in China, and to provide a basis for revising relevant design standards and specifications for cargo vehicle parameters, statistical methods were used to analyze the correlation and distribution characteristics of the external dimension parameters of two-axle trucks. Based on the analysis results, combined with the types of vehicles used for highway tolls, representative models for two-axle trucks and parking garage design models were determined. The study results showed that there is a strong positive correlation between the length and wheel space of two-axle trucks, whereas the correlation between wheel space and body width or height is relatively weak. The external dimensions are ranked as follows: heavy trucks > medium trucks > light trucks > micro trucks, with micro trucks having a significant difference in body width compared to other types of goods vehicles. Based on the data, it is suggested that the representative model for Type I trucks be determined as a light truck with external dimensions of 6.0 m × 2.55 m × 3.6 m, and the representative model for Type II trucks is a two-axle heavy truck with external dimensions of 12 m × 2.55 m × 4 m. The representative vehicle types and their external dimensions for truck parking garage design are as follows: micro trucks − 6 m × 2.1 m × 2.7 m, Type I trucks − 7.5 m × 2.55 m × 3.5 m, Type II trucks − 12 m × 2.55 m × 4 m.
