摘　　要：通过对某轻型飞机刹车失效进行分析,表明起落架走步是造成刹车失效的主要原因。进而提出在控制盒内机轮速度电路中增加低通滤波器、控制盒内阀门电压级增加特殊滤波器、起落架结构加固和降低刹车系统最大刹车压力等4种对策,解决了刹车失效问题。为现场短时间、低成本、有效地抑制起落架走步问题,避免刹车失效提供了有效的解决方案。Through the analysis of a light aircraft brake failure,it was shown that the gear walking was the main cause of brake failure.Four measures were proposed to solve this problem,including adding a low-pass filter in the wheel speed circuit in the control box,adding a special filter in the valve voltage level in the control box,reinforcing the landing gear structure and reducing the maximum brake pressure of the brake system.It provided a short-time,low-cost and effective solution to suppress gear walk to avoid a brake failure on side.
