Exploration of the design method of fuel pump parts structure optimization

With the continuous improvement of performance requirements for aircraft combat, transportation, and power, the weight requirements for aircraft are becoming increasingly stringent, and the demand for lightweight design of aircraft accessories is becoming increasingly urgent. The aviation fuel pump is the core component of the aircraft fuel system. It is of great significance to reduce the mass of redundant structures and improve the power to weight ratio of pumps while ensuring structural strength. Traditional fuel pump design mainly relies on the designer's experience in selecting structural forms and determining parameters. With the development of technology, especially finite element technology, important methods and means have been provided for strength analysis in the design process of fuel pump structures. However, in terms of design methods, pump design has not yet broken through the limitations of traditional empirical design, such as the determination of structural topology, selection of shape, and optimization of structural size parameters. This article explores the commonly used methods of structural optimization design, with a focus on introducing topology optimization theory and its applications . It takes the structural optimization design of a certain type of fuel pump component as the research object, in order to provide some theoretical reference for future fuel pump structural design optimization.
