Abstract

The present invention provides a low floor tramcar anti-bending system detection device and method. The device comprises a drive test bed; a test bed rack, a displacement sensor, a pull pressure sensor, a flow sensor and a hydraulic pressure sensor which are arranged on the drive test bed and a computer being in data transmission connection with each sensor, an anti-bending system is installed onthe test bed rack, the displacement sensor and the pull pressure sensor are arranged between the drive test bed and the test bed rack, the flow sensor and the hydraulic pressure sensor are connected with the anti-bending system, the drive test bed is in transmission connection with the test bed rack to drive the anti-bending system to simulate anti-bending motion of the anti-bending system on thetest bed rack when the curve driving of a low floor tramcar is performed, and the displacement sensor, the pull pressure sensor, the flow sensor and the hydraulic pressure sensor collect real-time state data of the anti-bending system in the motion process and transmit the real-time state data to the computer. The low floor tramcar anti-bending system detection device and method can effectively, really and reliably damping feature detection of the low floor tramcar anti-bending system.

Description

technical field [0001] The invention relates to a detection device and method for an anti-bending system of a low-floor tram, which is used for performance detection of the anti-bending system of a low-floor tram, and belongs to the field of performance testing of a low-floor tram. Background technique [0002] Low-floor trams are a kind of rail transportation that can replace subways and light rails in cities. They are favored by users because of their lower construction investment and operating costs than subways and light rails. In order to prevent undesired lateral displacement and yaw vibration of the car body when low-floor trams go through curves, most low-floor trams are equipped with anti-bending systems. The system damping characteristics of the anti-bending system need to be tested with test equipment. [0003] There is only one bogie under each car body of a low-floor tram, and every two bogies share a set of interconnected hydraulic systems, namely anti-bending...
