飞机数字电传防滑刹车系统污染控制方法研究

摘要

The work principles, using requirements and pollution control requirements for high precision electro⁃hydraulic servo valve were discussed from a view of solving oil pollution problem synthetically in braking control system. The pollution control methods and ways were proposed. Through controlling pollution in the aspects of design, utility and maintenance of the braking control system, braking wheels and hydraulic tubes, holding brake pressure in air and braking failures caused by hydraulic oil pollution could be effec⁃tively avoided.%从刹车系统污染综合治理角度出发，论述了飞机刹车控制系统中高精度电液伺服阀的工作原理、选用要求及污染度控制要求，提出了飞机刹车系统油液污染控制的方法和途径。通过在刹车系统、刹车机轮、刹车管路的设计、使用、维护等方面进行污染控制，能够有效避免飞机刹车系统在使用中由于污染问题导致着陆过程中出现空中带压、刹车失效现象。
