Abstract: This article summarizes and analyzes the engineering application of chassis lightweight technology in a domestic commercial vehicle enterprise. It analyzes the lightweight technology of chassis at home and abroad, as well as the future development trends and challenges. It proposes that the current main lightweight technology route for commercial vehicles is to adopt lightweight and high-strength advanced materials, and to integrate advanced optimization design methods with advanced manufacturing processes. The article focuses on listing the engineering application of chassis lightweight technology and the achieved weight reduction effects in the application of ultra-high-strength steel frame assembly, ultra-high-strength steel front lower protection, high-grade ductile iron front connecting beam, high-stress material leaf spring,aluminum alloy leaf spring bracket, and high-efficiency cooling module lightweight technology. This provides valuable engineering reference for technical personnel engaged in the development and research of chassis lightweight technology in the commercial vehicle industry.

Key words: Commercial vehicle; Chassis lightweight technology; Lightweight high strength material; Advanced design optimization method; Advanced manufacturing process
