Abstract: The deflector is one of the main components of the heavy truck, which can reduce the wind resistance, noise and fuel consumption of the vehicle. From the process point of view, this paper introduces the current situation of the assembly process of the heavy truck deflector, analyzes the existing problems and deficiencies from the aspects of assembly process, the work position, working hours, etc., optimizes the material of the deflector support, the assembly process, personnel quota, process layout, etc., and puts forward the optimization plan for the assembly process of the deflector. Meet the company's vehicle loading rhythm, reduce assembly difficulty and improve assembly efficiency.
