【摘要】介绍了一种采用电动静液作动器(EHA)代替原有液压作动机构的飞机多轮系防滑刹车系统,在重点分析EHA的系统组成原理和工作特性的基础上.建立了EHA及多轮系飞机刹车系统的数学模型,采用Matlab/simulink对其进行仿真.仿真结果表明:所建立的模型基本正确,结果与真实刹车基本吻合;采用EHA 代替液压系统能极大改善飞机刹车性能.%An electric hydrostatic actuator for aircraft anti-skid braking system instead of hydraulic pressure system is introduced. The system components principle of EHA and the features of work are described, and the mathematical models of multi-gear braking system and EHA are built up and simulated by Matlab/Simulink. Characteristic curves of simulation show that the whole simulation model is basically right,and the results are basically consistent with the real brake. The braking performance of aircraft can be greatly improved by using EHA instead of hydraulic pressure system.【总页数】4页(85-88)
