The invention belongs to the technical field of undercarriage system design, and relates to an undercarriage wheel bearing state detection method and an undercarriage wheel bearing state detection device. The temperature sensor and the gas pressure sensor collect temperature and pressure data of gas in the buffer gas cavity in real time and send the data to the signal interface device, and the signal interface device calculates the buffer load variation of the undercarriage wheel according to the temperature and pressure data and judges the bearing state of the wheel and whether the buffer gas cavity needs to be inflated or not. And an aircraft wheel grounding state signal is given according to the displacement threshold value. The current compression amount and volume change of the buffer can be accurately monitored without manual operation, a pressure gauge does not need to be manually connected to detect the pressure of an air cavity, the convenience is greatly improved, the structural change of the outer cylinder of the buffer is small, and the buffer is convenient to use.

    本申请属于飞机起落架系统设计技术领域,为一种起落架机轮承载状态检测方法及装置,在充气接头内设置温度传感器和气体压力传感器,温度传感器和气体压力传感器实时采集缓冲器气腔气体的温度和压力数据并发送至信号接口装置,信号接口装置根据温度和压力数据计算起落架机轮的缓冲器载荷变化量,判断机轮承载状态以及缓冲器气腔是否需要充气,并根据位移门限值给出飞机机轮接地状态信号。不需要人手动操作即可准确监控缓冲器的当前压缩量以及容积变化,不需要人工接入压力表检测气腔压力,便捷度大幅提高,并且对缓冲器外筒的结构变化较少,使用较为方便。
