Abstract
In order to accurately simulating the tribological behavior of center plate of bogie, a model was built to calculate the torsional kinematics parameters of the center plate when a railway freight-car bogie passes through a curve and a railway turnout. According to the torsional kinematics parameters, a plate-on-plate torsional friction tester was built. The variation of the torsional angle, angular speed, and angular acceleration of the center plate under different conditions was investigated. The torsional angle was affected by the distances between bogie centers and the radius of the railway circular curve. For different railway track geometries, the torsional angle of the center plate during bogie curve and turnout negotiation ranged within 0.016°–1.08° and 0.04°–1.96°, respectively. The torsional speed of the center plate under the turnout condition was much higher than that under the curve condition. The torsional friction behavior of a center plate material was simulated with the tester according to the calculated results.
