摘　　要：针对飞机自动防滑刹车系统易受污染导致刹车故障的问题,通过对现有防污染措施的分析,发现刹车系统在防反冲控制方面存在薄弱环节。分析各种型式滤材,选取锥形金属网作为防反冲油滤滤材。制造实验样件,进行常温、低温、含气的实验分析和寿命摸底实验。实验结果表明:低温和含气对正反向压力冲击和建压卸压时间有显著影响,该型滤材在寿命摸底实验后功能正常,性能仅轻微下降。Aiming at the problem of the aircraft’s automatic anti-skid brake system polluted easily and leading to the brake failure,through the analysis of existing anti-pollution measure,it was found the brake system had weaknesses in anti-recoil control.Various types of filter material were analyzed,conical metal mesh was chosen as the anti-recoil oil filter material.The prototype was manufactured,and the experiments of normal temperature,low temperature,high temperature,and gas-containing state and life test were conducted.The results show that low temperature and gas-containing state have a significant impact on the forward and reverse pressure shock and the pressure build-up and release time.The function of filter material is normal after the life test,and its performance is slightly degraded.
