Abstract

The invention provides a locomotive unit brake fatigue test device. The fatigue test device comprises a base, a wheel simulation unit and an action control module, wherein the base is used for installing a locomotive unit brake, the wheel simulation unit and the action control module are both arranged on the base, the wheel simulation unit is matched with the locomotive unit brake to realize wheelbrake simulation, and the action control module is used for controlling the action of the locomotive unit brake. According to the locomotive unit brake fatigue test device, four actions of independently controlling the unit brake to inflate, deflate, pull the bracelet solution and return the bracelet solution can be realized through the action control module, and the requirement that the braceletsolution needs to be independently tested in a type test is met. The invention further provides a test method adopting the fatigue test device, the test method is simple to operate and low in manualintervention degree, and the labor intensity of personnel is reduced.

Description

technical field [0001] The invention relates to the technical field of fatigue testing of locomotive components, in particular to a fatigue testing device and testing method for a locomotive unit brake. Background technique [0002] Some components on a locomotive require fatigue testing, such as locomotive unit brakes. [0003] For the unit brakes currently installed on power-concentrated trains, there is no fatigue test device with a high degree of automation and less manual intervention. A large amount of manpower and materials are required, and the test cycle is long, so it is difficult to achieve the expected effect of the test. [0004] In summary, there is an urgent need for a locomotive unit brake fatigue test device and test method to solve the problems in the prior art. Contents of the invention [0005] The object of the present invention is to provide a kind of locomotive unit brake fatigue test device, and specific technical scheme is as follows: [0006] A...
