摘　　要：针对液压缸优化设计问题,以液压机法兰支承液压缸为应用背景,在ANSYS软件中对液压缸进行有限元分析.建立以液压缸体积最小为优化目标的优化数学模型,提出一种自适应萤火虫算法求解模型对液压缸的结构参数进行优化.仿真结果表明,所提出自适应萤火虫算法比基本萤火虫算法收敛的精度更高,迭代次数更少,优化后液压缸的体积相对减少了42.3%,较好地解决了液压缸优化设计问题.进一步对优化后的油缸进行了有限元分析,验证了优化结果的正确性.Aiming at the optimization design of hydraulic cylinder,the hydraulic cylinder of hydraulic press flange is used as the application background,and the finite element analysis of the hydraulic cylinder is carried out in ANSYS software.An optimized mathematical model is set up with the minimum volume of the hydraulic cylinder as the optimum target.An adaptive firefly algorithm is proposed to optimize the structural parameters of the hydraulic cylinder.The simulation results show that the proposed algorithm improved the firefly algorithm than the basic convergence of higher precision,less iterations,the optimized hydraulic cylinder volume is relatively reduced by 42.3%,to solve the problem of optimal design of hydraulic cylinder.The finite element analysis of the optimized cylinder is carried out,and the correctness of the optimization results is verified.
