UIC54 UIC60 Railroad Rail Steel 22mm 24mm Bolt Hole Diameter OEM

KINGRAIL designed a method, device, system, medium and equipment for dynamic stiffness identification of a track structure, including: arranging at least one acceleration sensor on the rail of the track structure, and using an excitation tool to excite the rail of the track structure at least once to obtain the rail The first-order bending vibration frequency fr of the rail is obtained according to the acceleration time-history curve of the rail; and the first-order bending vibration frequency fr of the rail is substituted into the theoretical first-order bending vibration frequency formula of the rail, and the dynamic motion of the track structure is calculated. stiffness K. The application test of the invention has high application test efficiency, the operation can be completed in the maintenance skylight, the test equipment is simple, no special equipment is required, the operation is simple, the test operation can be completed by a single person, and the safety is good, and there is no need to install equipment on the rail. , the test tools can be completely withdrawn from the line without affecting the driving safety.
