[0043] Such as Figure 1a , Figure 1b , figure 2 As shown, before the test, place the longitudinal and transverse bearing devices 2-1 and 2-2 of the sleeper on the upper or side of the sleeper, place the acceleration or displacement sensor 1 on the upper part of the bearing device, and place the force sensor 5 on the side of the bearing device to fix , the tester host 3 is connected to the acceleration or displacement sensor 1 and the force sensor 5 respectively. During the test, the loading device 8 is held in hand, and a dynamic load is applied horizontally to the position of the force sensor, and the force sensor transmits the force to the sleeper through the bearing device, so that the sleeper is displaced. The dynamic load value and the resulting displacement change are measured by the force sensor 5 and the acceleration or displacement sensor 1 respectively, and the measured signal is transmitted to the tester host 3 through the cable, and the tester host 3 automatica...
