中文摘要
      提出了基于QFD(质量功能展开)的优化设计方法,以EHA(电动静液作动器)能耗最小和作动筒质量最轻为目标,满足强度约束条件,定义EHA系统的参数关系矩阵(PRM),建立其优化设计模型.以某型EHA设计参数为例,应用遗传算法进行了优化.优化后的EHA质量减轻23.57%,能耗降低36.46%.优化结果表明,该设计方法值得在EHA设计中推广应用.
英文摘要
      This paper proposed an optimization design method based on QFD (Quality Function Deployment). The EHA (Electro Hydrostatic Actuator) system parametric relationship matrix (PRM) and constraint conditions were defined with the minimum energy consumption and the lightest actuator mass as the objective to establish its optimal design model. Finally, the genetic algorithm was used to optimize a certain type of EHA design parameter as an example. After optimization, the weight of EHA was reduced by 23.57% and the energy consumption was reduced by 36.46%. The optimization results show that this design method is worthy of promotion and application in EHA design.
