Problems solved by technology

This method is relatively simple, but the software simulation is only an ideal situation, and cannot fully consider the suspension system and force status of the actual train, so there is a certain gap with the actual test

Embodiment approach

[0106] The specific implementation method is:

[0107] 1) Control the two vertical actuators 9 below the test platform 1 so that the four vertical actuators 9 below the front and rear test platforms 1 maintain the same height. Record the height difference between the left and right sides of the surface of the test platform 1, and calculate the angle δ formed by the test platform 1 in the left and right direction. Measure the angle η formed by the hanging plumb line above the surface of the end of Train 2 and the location marked in Step C.

[0108] 2) Control the two vertical actuators 9 below the front end test platform 1, so that one vertical actuator 9 moves upward for a certain distance, the other vertical actuator 9 keeps its position unchanged, and the rear end test platform 1 Two vertical actuators 9 below also keep the position unchanged. Record the height difference between the left and right sides of the surface of the test platform 1, and calculate the angle δ form...

Abstract

The invention relates to a rail vehicle operation performance testing device which comprises test platforms and degree-of-freedom excitation devices arranged on the test platforms and used for simulating different track situations. The test platforms are arranged below steering frames of a train to be tested, each degree-of-freedom excitation device comprises a vertical excitation device body and / or transverse excitation device body and / or longitudinal excitation device body, and weight balancing equipment is arranged in the train. Tests can be carried out on different rail vehicles in different rail distances, and if the testing device is used to the largest extent, testing capital can be saved and accuracy of a test result is guaranteed. Besides, the device can simulate different track curves, different slops, different track superelevations and the like according to actual situations so as to reach true track operation situations. Accordingly, actual operation situations of the vehicle to be tested in a real track can be simulated, so that curve passage capacity, vertical shock absorber performance and the flexibility coefficient are measured, real and effective test data are provided for train operation performance researches, and the method plays an important role in guaranteeing safe operation of high-speed railways.

Description

technical field [0001] The invention relates to a rail vehicle performance test device, in particular to a rail vehicle running performance test device capable of simultaneously measuring vertical shock absorption performance, curve passing ability and flexibility coefficient, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] With the development of railway transportation, railways have been laid to all parts of the country. Due to the large land area of ​​our country and the great differences in topography and landforms, various curved roads have appeared in the construction of railways, such as S-shaped curves, vertical convex Curves, vertical concave curves, etc., in order to better adapt to various routes and ensure that various vehicles can operate safely in various curved curves, the vehicle's curve passing ability is considered in vehicle design. Moreover, with the development of high-speed and heavy-duty railway transport...
