Abstract

The invention relates to a multifunctional braking power testing platform which comprises the components of a base; a power and inertia chamber which is arranged on the base and comprises a power unit and a mechanical inertia unit; a first testing chamber which is arranged on the base and is mounted on one end of the power and inertial chamber; and a second testing chamber which is arranged on the base and is mounted on the other end of the power and inertia chamber, wherein a first braking device in the first testing chamber is different from a second braking device of the second testing chamber. The multifunctional braking power testing platform can be used for disc braking, tread braking, eddy current braking or magnetic rail braking tests of high-speed train and other rail vehicles, thereby reproducing a braking energy conversion process in a 1:1 manner and testing braking performance in real time.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a multifunctional braking power test bench for high-speed trains or other rail vehicles. Background technique [0002] The brake dynamic test bench is the key test equipment for the vehicle braking system. On the braking power test bench, the load is configured according to the actual braking energy or a certain proportion, and the speed regulation and braking are performed; during the conversion of braking energy, various performance tests and experiments are carried out on the braking device. [0003] Specifically, the brake dynamic test bench is an inertial dynamic test system, which is a test equipment designed and built for research and testing of brake devices. The brake dynamic test bench generally has the functions of load simulation, drive speed regulation, braking, data acquisition and analysis. The basic principle of the test bench is to use an energy stor...
