Abstract: Green design pursues maximum economic efficiency and minimum environmental impact. Green design of mechanical equipment can ensure environmentally friendly design and manufacturing. A rust-off machine is a crucial piece of equipment in remanufacturing. As attention to remanufacturing grows, the demand for rust-off machines is gradually increasing, but their green characteristics have not attracted attention. There is a need to carry out a green design for a rust-off machine that can improve its economy and environmental friendliness. In response to this need, in this study, a green design method for a rust-off machine was developed, combining the strengths of quality function deployment for environment (QFDE) and function analysis. In this method, functional analysis was used to determine the mapping relationship between functions and components. QFDE was used not only to determine the relationship between customer requirements and engineering metrics, but also to establish the relationship between engineering metrics and components and to obtain optimal structural solutions. A green design of a steel plate surface rust-off machine was taken as a case study. The results show that this method can achieve a win-win design that achieves maximum economic benefit and environmental protection.
