| description | To study the simulation effect of rail plate harmonic displacement excitation on wheel high-order wheel polygon geometric excitation, a wheel-plate rolling contact finite element model was developed based on simulation analysis software for the bogie high-frequency excitation test bench. The wheel-plate rolling vibration behaviors under 20<sup>th</sup>-order polygon excitation with a wave depth of 0.05 mm were investigated through a solving process at a speed of 440 km/h. A comparative analysis was then conducted in both the time domain and frequency domain to identify similarities and differences between the two excitation modes. The simulation results for a 20<sup>th</sup>-order polygon with a wave depth of 0.05 mm, under an axle weight of 17 t and a speed of 440 km/h, show that the maximum time-domain wheel-plate vertical force differed by only 1.5% between displacement excitation and geometric excitation. The spectral peak of wheel-plate vertical forces and the power spectral density (PSD) peak of axle box accelerations at the polygon excitation frequency of 840 Hz under displacement excitation are in good agreement with those under geometric excitation. The constant local curvature radius at the wheel-plate contact point under displacement excitation results in a larger contact spot area and a corresponding 21.7% reduction in contact stress. The amplitude of the wheel-plate vertical force spectrum and the power spectrum density of axle box accelerations increase with higher rail plate displacement amplitudes, while the peak frequency is basically unchanged. In summary, wheel polygon can be effectively simulated using displacement excitation as an alternative to geometric excitation on the bogie high-frequency excitation test bench. |
