Abstract: As an important part of the long head heavy truck, side protection is greatly limited by many factors such as chassis empty question, modeling effect, convenience of disassembly and assembly, and the harsh working conditions of the whole vehicle position, the design is much more difficult. The paper discusses the design study of side protection system at long head heavy truck. It recites the design requirements and structural design process of the side protection system. Finally, the structural performance and failure modes of side protection system are described. It provides reference and methods for the design and development of side protection systems.
