Turnout switch rail mounting device vibration source identification test method

The invention relates to a vibration source identification test method for a turnout switch rail mounting device. The device comprises an indication rod (1), a switch rail (2), a joint (3), tip iron (4), a switch machine (5), a supporting plate (6), a vibration acceleration sensor (7) and a data acquisition instrument (8). The indication rod (1) is in bolted connection with the point switch (5), the point switch (5) is in bolted connection with the supporting plate (6), the indication rod (1) is connected with the connector (3) through a shaft sleeve and a nut, and the connector (3) is connected with the tip iron (4) through a bolt; the tip iron (4) is connected with the switch rail (2) through a bolt; and the vibration acceleration sensor (7) is connected with the data acquisition instrument (8) through a sensor wire. According to the vibration source identification test method for the turnout switch rail mounting device, historical data is not needed, and the direction of the vibration source can be rapidly
