航空轮胎间接式胎压检测与拖胎磨损预警研究

摘要

提出一种基于ABS轮速传感器定距离脉冲数的间接式胎压检测与拖胎磨损预警新方法.在MATLAB中建立主机轮系统仿真模型,通过机轮标定、定距离脉冲数修正、平均值比较法、同异侧机轮比较法、定距离最小脉冲数设定、定距离阈值标定以及小样本数据统计等方法,成功检测出了飞机两侧主轮胎压力,同时对4个主机轮的拖胎磨损进行了预警.通过仿真计算,验证了间接测量方法的可行性.%A new method for the indirect monitoring tire pressure and the early warning on tire sliding wear was proposed,which is based on the pulse number of certain distance for ABS wheel speed sensor.The simulation model of host wheel system was established in MATLAB.Some new methods,including calibration of wheel,pulse number correction of the fixed distance,mean value comparison,same or different aircraft wheel comparison,minimum pulse number set of the fixed distance,threshold calibration of the fixed distance and small sample statistics,have been successfully used to detect both sides of the aircraft tire pressure and the four main wheels sliding wear numerically.The feasility of indirect monitoring method is verified by numerical simulations.
