摘　　要：液压伺服系统应用十分广泛,可靠性与使用寿命是人们非常关心的问题。要提高可靠性,必然会影响成本、体积和重量,因而在配置上需要优化。提出了液压系统可靠性最优化原则,应用这些原则能合理地优化系统。同时,还叙述了冗余设计应考虑的几个问题,并通过MATLAB软件仿真一具体实例来实施最优化原则与冗余技术。The hydraulic servo system is widely applied,but the reliability and service life is a matter of great concern to the people. Improving the reliability will inevitably affect the cost,volume and weight so that optimization is necessary in the configuration. Therefore,we present a hydraulic system reliability optimization principle. The applications of these principles can help optimize system reasonably. At the same time we describe a few questions that the redundancy design should consider. The optimization principle and redundancy technology are implemented by MATLAB through a specific example.
