Abstract

The invention discloses a rail vehicle wheeltrack relationship test bench. The bench comprises a rail wheel device, a wheel suspension device, a loading device, a measuring device and a control system, the rail wheel device simulates an actual steel rail; the loading device applies a load to the test wheel, the wheel suspension device transmits the load to the test wheel, the measuring device collects data of other devices and sends the data to the control system, the control system calculates the collected data and obtains a test result, automatic operation of the test is ensured, and the risk of manual control errors is avoided. The bench can be used for carrying out various tests in the wheel-rail relation field. Compared with the prior art, the test cost is reduced on the premise thatthe requirement for the highest test speed is met, in addition, the test bed can simulate line disturbance in the test process, the running state of wheels is close to the actual running state, the test result has higher reference value, and meanwhile the test requirements of various rail vehicles are met.

Description

technical field [0001] The application relates to the technical field of rail transit test equipment, in particular to a rail vehicle wheel-rail relationship test bench and a test method using the same. Background technique [0002] In the development of high-speed railways, the research on wheel-rail relationship is one of the hot research directions. The wheel-rail relationship has an important impact on the safety, comfort and line maintenance of vehicle operation. For the experimental research on the wheel-rail relationship, there are two methods: field test and laboratory test. [0003] The wheel-rail relationship test in the field test has the following defects: because it needs to be carried out on the actual line, the test period is long, the cost is high, and it is susceptible to weather and environmental interference; and, for fatigue cracks, wheel damage, derailment, etc. For the tests in other aspects, it is not suitable to be carried out on site due to the rela...
