Abstract

The invention provides a locomotive deflection test method and a locomotive deflection test device, and belongs to the technical field of safe operation of locomotives. The method comprises the following steps of connecting an auxiliary test locomotive to at least one side of the running direction of a to-be-tested locomotive; determining a reference point on a first vehicle body surface of two opposite vehicle body surfaces of the to-be-tested locomotive and the auxiliary test locomotive, and determining a projection point of the reference point on a second vehicle body surface of the two vehicle body surfaces as a first projection point; performing trial operation on the to-be-tested locomotive and the auxiliary test locomotive together, and determining a projection point of the reference point on the second locomotive body surface as a second projection point; and based on the deviation degree of the first projection point and the second projection point, determining the anti-deflection performance of the to-be-tested locomotive. According to the invention, the anti-deflection performance of the locomotive can be simply and conveniently tested.

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...
