Nonlinear Analysis on Hunting Stability for High-Speed Railway Vehicle Trucks on Curved Tracks

Abstract: Based on the heuristic nonlinear creep model, the nonlinear coupled differential equations of the motion of a ten-degree-of-freedom truck system, considering the lateral displacement, the vertical displacement, the roll and yaw angles of the each wheelset, and the lateral displacement and yaw angle of the truck frame, moving on curved tracks, are derived in completeness. To illustrate the accuracy of the analysis, the limiting cases are examined. The influences of the suspension parameters, including those los… Show more

“…To reduce the time cost for numerical analysis, one bogie model had been applied instead of a vehicle model [16,21]. However, it is rarely used except some special cases because the stability of a bogie cannot represent that of a vehicle.…”

“…Kalker's linear creep theory has been modified with the function of creep force saturation to evaluate the creep forces acting on the wheel-rail interface [24,25]. The unlimited creep forces and moments at the left and right contact planes are solved by utilizing Kalker's linear theory as * = − 33…”

“…The conventional suspension system for a passenger vehicle usually has two levels: the axle's suspension, stiffer, to provide safety and the suspension of the carbody, softer, to offer best ride quality [2]. Having in view the importance of the lateral oscillations phenomenon numerous authors have dedicated studies to this issue [3][4][5][6][7][8][9][10][11]. There are possibilities to increase vehicle's speed by an appropriate design of the passive suspension but this approach proves to have limits.…”
