【摘要】 近些年,针对典型的带旁路单回路液压系统,已经有研究成功地建立了在不确定条件下系统污染控制的数学模型。本文在此基础上提出一种基于L-R型模糊线性规划的方法。以带旁路过滤器的典型单回路液压系统作为基本研究对象,以系统的运行成本作为目标函数,以系统的运行风险作为约束集,建立了以降低系统运行成本,提高系统运行可靠度为目的的过滤器优化配置数学模型,优化了过滤策略;同时对系统中外界污染颗粒的侵入率和过滤器的纳垢容量等进行了模糊处理,与以往的优化算法进行比较,充分显示了该算法的优点。更多还原

【Abstract】 In recent years,there have been some researches successfully established the mathematical model for FPS contamination control under conditions of uncertainty.Based on this,the LR-type fuzzy linear programming method was proposed in this paper.With the single-loop hydraulic system with bypass filter taken as the basic research object,the system operating costs as the objective function,the operational risks of the system as a set of constraints,the model aimed to decrease the risk and cost of system is established,and the strategies of filter allocation and replacement are optimized.Meanwhile,the contaminant ingression rate and filter contaminant holding capacity are expressed as fuzzy sets.Compared with the previous optimization algorithms,it shows the advantages of the algorithm.更多还原
