摘要
电动静液作动器(EHA)是一种起源于航空领域的新型高性能伺服作动装置,正逐渐成为各类大型装备的通用基础元部件,鉴于其机电液控热多学科耦合较大且要达到的综合指标又高,所以迫切需要一套高效科学的设计方法。从EHA完整设计过程的角度,综述其中的设计方法,为今后EHA产品的设计开发流程提供了基本支撑和多样化的技术手段。总结出基于自动化系统设计和多学科联合详细设计的EHA设计方法,并对其中的综合指标建立、建模仿真、优化设计、控制设计等关键技术进行了分析,给出适合不同设计任务特点的各步骤实现途径。展望了自动化详细设计、基于模型系统工程、3D打印等最新技术在EHA设计中的应用,为后续进一步提升EHA设计水平提供了参考。
Electro-hydrostatic actuator （EHA） is a novel high-performance servo actuator originating in the field of aviation and is becoming a common basic component of major equipment. Research is ongoing to develop an efficient and scientific design method of EHA due to its multidisciplinary coupling and high com- prehensive indicator. A review on EHA design method is put forward with special consideration to the complete design process, providing a basic support and diverse technical means for the EHA product development process. Key technologies such as comprehensive index establishment, modeling and simulation, optimization design and control design are listed and analyzed. Focusing on automation-based preliminary design and multi- disciplinary optimization-based detailed design, this paper suggests the implements of each step for different design needs. Applications of newly developed technologies such as automated detailed design, model based system engineering and 3D printing to EHA design are introduced.
