Abstract: The frame assembly is one of the core components of the heavy truck, which carries various functional assemblies of the vehicle and is known as the backbone of the heavy truck. With the rapid development of the national economy, customers have new requirements for heavy truck products with low fuel consumption, multiple configurations, high horsepower and long life cycle, but the existing heavy truck frame assembly manufacturing process can not fully meet these new requirements. This paper has carried out discussions on customer demand interpretation, process status analysis, feasibility analysis of advanced manufacturing technology and other aspects, and concluded that lightweight material molding, flexible rapid drilling, local deformation of longitudinal beam electrophoresis of spare parts and other products are in line with the technological route of the development of heavy truck industry, and also form the development trend of the current frame assembly manufacturing.
