摘　　要：以锚绞机液压系统为研究对象,利用AMESim软件进行故障仿真分析,建立故障物理模型;应用可靠性仿真和优化设计等方法,进行液压系统稳定性优化建模,给出优化设计方案。考虑到液压响应非线性强,为提高优化计算效率和收敛性,采用试验设计和径向基函数相结合的响应面模型拟合方法。结果表明:相对于原方案,液压系统优化方案的可靠性、稳定性得到大幅度提升。系统的稳定性从68%提高到89%,可靠性从0.143和0.414提高到0.81以上。The operational reliability of hydraulic windlass directly affects the stability and safety of ship equipment.This article took the anchor winch hydraulic system as the research object,analyzed its failure mechanism.We established and simulated its physical model by AMESim software,and analyzed its failure.Through the application of reliability simulation and optimization design methods,the hydraulic system was designed,modeled and solved,and finally an optimized design plan was given.Considering that the hydraulic system response with strong nonlinear,in order to improve the efficiency and convergence of optimization calculation,a response surface model fitting method combining experimental design and radial basis function was studied.These results show that:compared with the original scheme,the reliability and stability of the new hydraulic system optimization scheme have been greatly improved.The stability of the system increased from 68%to 89%,and the reliability of the system increased from 0.143 and 0.414 to over 0.81.
