[0002] Rail corrugation refers to a kind of approximate wavy wear that occurs on the surface of the rail after the rail is put into operation with a certain regularity of periodic wear and plastic deformation on the working surface of the rail. In the rail corrugation, the phenomenon of spring breakage caused by rail corrugation occurs frequently, especially in small radius curves. After the spring breaks and splashes, it will cause some safety risks. , w

Abstract

The embodiment of the invention provides a railway fastener elastic strip breakage splashing risk prediction method and device, and relates to the technical field of traffic safety. The method comprises the following steps: establishing a three-dimensional nonlinear finite element model and setting the three-dimensional nonlinear finite element model in a service state; establishing a coupling space simulation model of the vehicle and the steel rail; according to the coupling space simulation model, dynamic response data between the vehicle and the steel rail under the condition of corrugationof the steel rail are obtained, inputting the dynamic response data as excitation into a three-dimensional nonlinear finite element model; fracture splashing risk data of the elastic strip is obtained. The method has the advantages that the spatter track can be simulated according to the fracture spatter risk data, accordingly, spatter risks of the elastic strips can be predicted according to thefracture spatter risk data of the elastic strips, risk prediction results can be acquired, comprehensive protection measures can be taken for fracture spatter of the elastic strips, and safe runningof trains during running can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a method and device for predicting the risk of splashing when a railway fastener elastic strip breaks. Background technique [0002] Rail corrugation refers to a kind of approximate wavy wear that occurs on the surface of the rail after the rail is put into operation with a certain regularity of periodic wear and plastic deformation on the working surface of the rail. In the rail corrugation, the phenomenon of spring breakage caused by rail corrugation occurs frequently, especially in small radius curves. After the spring breaks and splashes, it will cause some safety risks. , has brought a threat to the normal operation of the train. [0003] In the existing technology, the understanding of the clip fracture splash is not sufficient, and the safety protection measures for the clip fracture splash are generally carried out through engineering experience, so that it is imp...
