Abstract

The invention discloses a comprehensive test method of wheel-rail force. The method includes: setting a first vertical force sensor at the bottom of a mounting fastener of a steel rail to be tested, and setting a second vertical force sensor in a spring bolt connection portion of the mounting fastener; setting a transverse force sensor on the side of the mounting fastener of the steel rail to be tested; applying a test vehicle to a position over the steel rail to be tested, and detecting rail down-pressure R, spring forces T1 and T2 and side transverse forces H1 and H2; acquiring vertical force P of the steel rail to be tested and transverse force H thereof according to the rail down-pressure R, the spring forces T1 and T2 and the side transverse forces H1 and H2. Therefore, the problems that measurement precision is low and a measurement process is complex to operate are solved. The method has the advantages such that testing precision is high, stability is good, installation is simple, the devices can be uniformly installed with existing fasteners, and no influence is caused to the structural uniformity of the rail.

Description

technical field [0001] The invention relates to the technical field of vehicle-track wheel-rail force detection and monitoring, and is applied in the process of track monitoring and vehicle operation safety monitoring, in particular to a comprehensive testing method and device for wheel-rail force. Background technique [0002] In order to ensure the safe operation of the high-speed railway after laying, it is necessary to accurately monitor the vehicle-track wheel-rail force during the operation process to ensure the safe operation of the track and the vehicle. However, due to the narrow clear space between the underside of the rail and the surface of the ballastless track slab, an effective measurement cannot be performed. In view of the above problems, in the prior art, the method of rubber force-measuring pads is generally used to detect the vertical wheel-rail force, but the rubber force-measuring pads need to be laid under the track nodes to be detected during implemen...
