Abstract

The invention discloses a magnetic track brake suction test system and method. The system comprises a mounting base (8), wherein a plurality of mounting pads (1) for supporting a magnetic track brakeare mounted at the top of the mounting base, a driving cylinder (7) is vertically installed on the lower portion of the mounting base, a piston rod of the driving cylinder is arranged upwards, an integral steel rail (2) is installed at the top of the piston rod of the driving cylinder and located in a space defined by the mounting pads, and a force sensor (9) is installed between the steel rail and the piston rod. According to the invention, the maximum tension on the integral steel rail is measured through the force sensor, the suction value of the magnetic track brake can be directly obtained without conversion, the result is more accurate and efficient, and the measurement method is more convenient.

Description

technical field [0001] The invention relates to a rail transit vehicle braking system, in particular to a magnetic rail brake suction test system and method. Background technique [0002] The magnetic rail brake is an indispensable braking component in the braking system of rail transit equipment, and the electromagnetic suction is the key technical index of the magnetic rail brake, and the magnitude of its suction directly affects the braking distance of the rail vehicle. Therefore, it is very important to measure the suction value of the magnetic rail brake efficiently and conveniently for the safety of the service brake. [0003] At present, there are many methods for measuring the suction force of magnetic track brakes. The commonly used measurement method is: measure a small section of the magnetic track brake with a tension meter and a force sensor, and then convert the full length of the magnetic track brake in proportion to obtain the suction value. Because there a...
