摘　　要：液压缸是液压系统中至关重要的执行元件,其设计性能直接影响系统的效率、稳定性及可靠性。针对液压缸的优化需求,本文采用Ansys软件结合多目标优化算法,开展了液压缸的多目标优化设计研究。基于有限元分析,建立了液压缸的静力学与模态分析模型,随后以最大应力、最大变形和质量为优化目标,综合考虑强度和刚度等设计约束,构建了优化模型。通过对关键结构参数的优化分析,结果表明,优化设计不仅能够有效降低液压缸的质量,还能够提高其使用寿命和工作可靠性。本研究为液压缸的优化设计提供了理论依据和实践参考,具有一定的工程应用价值。The hydraulic cylinder is a crucial actuator in the hydraulic system,and its design performance di-rectly 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-ob-jective 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 es-tablished.With the maximum stress,maximum deformation and mass as the optimization objec-tives,and comprehensively considering design constraints such as strength and stiffness,an opti-mization 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 en-gineering application value.
