Abstract

The invention relates to a brake system testing stand and more particularly to a high-precision multifunctional subway vehicle brake system testing stand and the application method thereof with the object to solving the technical problems existing in the prior art that the brake valve testing can achieve only a single function with poor universality, that the testing is targeted only to a specific valve, that the intelligent degree is low and that the overall testing accuracy is not high enough. The testing stand of the invention comprises a machine frame. The machine frame is provided therein with an industrial PC machine. The industrial PC machine is connected with a data acquisition card, a printer, and an Ethernet switch. The Ethernet switch is connected with a servo motor controller, an electromagnetic valve, a pressure sensor, an electric proportional valve, and a pressure display table through a PLC. The servo motor controller is connected with the servo motor; the electromagnetic valve is connected with an air control valve; the outer surface of the machine frame is provided with a height valve testing tool and a valve plate. The valve plate is provided with six interfaces with each interface being communicated respectively with the electromagnetic valve, the pressure sensor, the electric proportional valve, the pressure display table and the air control valve through the air channels.

Description

technical field [0001] The invention relates to a braking system test bench, in particular to a high-precision multifunctional metro vehicle braking system testing bench and a using method thereof. Background technique [0002] Brake valve is an important part of the brake system in the brake system of subway vehicles, such as the height valve, which is used to control the pressure of the air spring and the height of the car body. When there is a height change between the car body and the bogie due to the load of the car, the height valve can adjust the inflation and exhaust of the air spring. Keep the car body in a balanced state. The safety valve can ensure that the pressure of the gas system does not exceed the maximum allowable value. The ball valve and the solenoid valve can control the on-off of the air circuit to realize the control of the braking of the subway vehicle. The normal operation of these brake valves is a necessary condition to ensure that the subway ve...
