Abstract

The disclosure provides a locomotive deflection test method and a locomotive deflection test device, which belong to the technical field of locomotive safe operation. The method includes: connecting an auxiliary test locomotive on at least one side of the running direction of the locomotive to be tested; determining a reference point on the first body surface of the two opposite body surfaces of the locomotive to be tested and the auxiliary test locomotive, and Determining the projection point of the reference point on the second body surface of the two vehicle body surfaces, which is the first projection point; conducting a trial run of the locomotive to be tested and the auxiliary test locomotive to determine the reference point The projection point of the point on the second body surface is a second projection point; based on the degree of offset between the first projection point and the second projection point, the anti-deflection performance of the locomotive to be tested is determined. The disclosure can simply and conveniently test the anti-deflection performance of the locomotive.

Description

technical field [0001] The disclosure relates to the technical field of locomotive safe operation, in particular to a locomotive deflection test method and a locomotive deflection test device. Background technique [0002] With the rapid development of railway transportation, the problems of locomotives in terms of heavy load, high speed and safety have aroused people's special attention. Railway heavy-duty locomotives have the characteristics of large axle load, high power, and high adhesion. They are usually organized in multiple locomotives, such as figure 1 Shown, towing long freight trains of high orders of magnitude weight. During the normal operation of heavy-duty trains, when the train is running in the braking state, affected by factors such as the length of the train formation, the asynchronous braking of the front and rear of the train, and the large inertia, the heavy-duty locomotive often has to bear a large force at the coupler. The effect of longitudinal imp...
