Embodiment Construction
[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0021] The invention provides a method for judging sliding in a rolling experiment, such as figure 1 shown, including the following steps:
[0022] A. According to the actual line operation standard of rail vehicles, set the idling judgment value σ 1 and sliding judgment value σ 2 ;
[0023] B. Test the speed v of the locomotive wheel set respectively c and the speed v of the track wheel g , k=v c / v g ;
[0024] C. Put k and σ 1 , σ 2 Compare,
[0025] If k>σ 1 , to determine that the locomotive wheel pair is sliding relative to the rail wheel;
[0026] If ...

The invention provides a method for judging sliding in a rolling experiment and further provides an anti-sliding device used for a rolling testboard. The anti-sliding device is composed of a speed sensing assembly, a controller and a clutch, wherein the speed sensing assembly comprises a light reflected code disc, a photoelectric rotation speed sensor and a torque rotation speed sensor; the photoelectric rotation speed sensor is used for detecting the rotation speed of wheel pairs of a locomotive, and the torque rotation sped sensor is used for detecting the rotation speed of a track wheel; the controller is used for receiving locomotive wheel pair rotation speed signals and track wheel rotation speed signals, making a judgment on sliding by using the method provided by the invention and transmitting a judgment result to the clutch; and the clutch is used for disconnecting or connecting the track wheel and a transmission mechanism. According to the anti-sliding device provided by the invention, the rotation speeds of the wheel pairs of the locomotive and the track wheel are monitored and tested, and a real-time judgment is made, so that the problem that the wheel pairs of the locomotive slide or idle relative to the track wheel in a rolling test process can be effectively solved.
Description
technical field [0001] The invention relates to a test system of rail transit equipment, in particular to a method for judging sliding in a rolling test and an anti-skid device for a rolling test stand. Background technique [0002] The locomotive anti-skid control technology was born at the beginning of the last century and has been developed very maturely. Various anti-skid devices are also widely used on locomotives, bullet trains and other rail transit vehicles, but the anti-skid protection device of the rolling test bench system is blank. Rolling test is a test method for rail vehicle to simulate line operation. Traction test, braking test and dynamic test are frequently carried out test items in rolling test of rail vehicle. In these test items, it is inevitable that similar lines will appear Sliding phenomenon will occur. [0003] The rolling test bench uses rotating rail wheels to simulate infinitely long steel rails. Once the locomotive wheel pair slides on the rai...
