The invention provides a rail stress detection method and a rail stress detection device. The rail stress detection method comprises the steps of sending an excitation electric signal to an ultrasonictransmitting probe; controlling the ultrasonic transmitting probe to transmit an ultrasonic signal to a track, and determining the transmitting time of the ultrasonic signal; controlling at least oneultrasonic receiving probe to receive the ultrasonic critical longitudinal wave signal, and determining the receiving time of each ultrasonic receiving probe in the at least one ultrasonic receivingprobe for receiving the ultrasonic critical longitudinal wave signal; and according to the transmitting time of the ultrasonic signal and the receiving time of each ultrasonic receiving probe in the at least one ultrasonic receiving probe for receiving the ultrasonic critical longitudinal wave signal, determining the change of the stress borne by the track between the ultrasonic transmitting probeand each ultrasonic receiving probe in the at least one ultrasonic receiving probe. Continuous advancing stress detection can be realized, and the stress distribution condition on the whole line canbe obtained. A basis is provided for determining the position of track stress relief.

    本申请提供一种轨道应力检测方法和轨道应力检测装置,包括:向超声波发射探头发送激励电信号;控制超声波发射探头向轨道发射超声波信号,并确定超声波信号的发射时间;控制至少一个超声波接收探头接收超声波临界纵波信号,并确定至少一个超声波接收探头中的每个超声波接收探头接收到超声波临界纵波信号的接收时间;根据超声波信号的发射时间以及至少一个超声波接收探头中的每个超声波接收探头接收到超声波临界纵波信号的接收时间,确定超声波发射探头与至少一个超声波接收探头中的每个超声波接收探头之间的轨道所承受的应力变化。可以实现连续行进应力检测,可以得到整体线路上的应力分布情况。为轨道应力放散的位置确定提供依据。
