Modeling and simulating of center plate torsion behavior during bogie curve and turnout negotiation
Wang Shibo,Mao Yong,Teng Bing,Pan Li 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.7
In order to accurately simulating the tribological behavior of center plate of bogie, a model was built to calculate the torsional kinematicsparameters of the center plate when a railway freight-car bogie passes through a curve and a railway turnout. According to the torsionalkinematics parameters, a plate-on-plate torsional friction tester was built. The variation of the torsional angle, angular speed, andangular acceleration of the center plate under different conditions was investigated. The torsional angle was affected by the distancesbetween bogie centers and the radius of the railway circular curve. For different railway track geometries, the torsional angle of the centerplate during bogie curve and turnout negotiation ranged within 0.016°-1.08° and 0.04°-1.96°, respectively. The torsional speed of thecenter plate under the turnout condition was much higher than that under the curve condition. The torsional friction behavior of a centerplate material was simulated with the tester according to the calculated results.
