The hydraulic cylinder is a crucial actuator in the hydraulic system, and its design performance directly affects the efficiency, stability and reliability of the system. In response to the optimization requirements of the hydraulic cylinder, this paper adopts Ansys software combined with multi-objective optimization algorithms to conduct multi-objective optimization design research on the hydraulic cylinder. Based on finite element analysis, a static model of the hydraulic cylinder is established. With the maximum stress, maximum deformation and mass as the optimization objectives, and comprehensively considering design constraints such as strength and stiffness, an optimization model is constructed. Through the optimization analysis of key structural parameters, the results show that the optimized design can not only effectively reduce the mass of the hydraulic cylinder, but also improve its service life and working reliability. This study provides a theoretical basis and practical reference for the optimization design of hydraulic cylinders and has certain engineering application value.
