摘　　要：针对提高复杂机电液一体化产品-飞机电静液EHA可靠性的问题,研究了基于GO法的EHA可靠性计算方法,提出了一种电静液作动器EHA可靠性的GO分析设计方法,完成了具有多组件余度参数的EHA作动器GO图和GO运算,推导了其可靠度计算公式,得出了高可靠性EHA设计的相关理论,给出了GO法应用于EHA余度设计的新思路。设计算例表明,这种基于GO法的EHA可靠性分析设计方法计算精确,能很快得出较优余度设计参数,是一种可行的系统性分析设计方法。Aim at the reliability enhancement problem of complex mechanics-electronics-hydraulics integration products-aircraft Electric Hydrostatic Actuator（ EHA）,the method to calculate EHA reliability based on GO methodology is studied,and a new GO analysis and design method for EHA reliability is proposed. The GO plot and GO operation of EHA with multi-component redundancy parameters are presented. The reliability calculation formula of EHA with multi-component redundancy is derived. The design theory of EHA with high reliability is obtained. A new approach to apply GO method to EHA redundancy design is provided. The design example shows that the EHA reliability analysis and design method based on GO methodology has the advantage of high computation accuracy,and it can obtain the optimal redundancy design parameters rapidly. This method is viable in systematic analysis and design for EHA reliability.
