摘要
针对飞机作动系统的发展状况,设计了一种一体化电静液作动器(EHA)。在分析EHA的工作原理和设计特点的基础上,对电机、泵和作动缸的选用及系统性能的设计进行了优化。分析了EHA各个模块的数学模型,并在Matlab/Simuink环境下对各个部件的模型进行了仿真和结果分析,讨论了结构参数对整个系统性能的影响,设计了合理有效的控制算法,建立了整个系统的数学模型,给出了系统在不同输入信号下的仿真结果。结果表明,设计的EHA系统模型合理,满足性能指标。
According to the development trend of aircraft system,a new aircraft electro-hydrostatic actuator（EHA） is designed.In order to meet the need for design characteristics for the electro-hydrostatic actuator,the specific requirements,the system design and selective principles of the motor,pump and hydraulic cylinder are given.Furthermore,the mathematical model of each module is created and the module＇s simulation result is given in the Matlab/Simulink.Then the whole mathematic model is created.And the effects of all structural parameters on the performance are also analyzed.The best control algorithm is chosen.The results of the system in some different input signal simulation show that the design of the system model for EHA is reasonable to meet the aircraft performance.
