Abstract: The structure and working principle of the composite air suspension system used in the rear suspension of a dangerous goods transport vehicle were described. Taking the fracture of the guide arm support as an example, a fault tree was established from the aspects of product design, production and assembly. Based on theoretical analysis and bench tests, the main causes of failures were investigated and located in detail, and parts were improved and optimized. Through finite element analysis and calculation, the improvement measures were effective, and the test on the uneven road of the whole vehicle was successfully completed, which would provide solutions for similar faults and provide a basis for the reliability design of such parts.
