Influence of Wheelset Structural Flexibility on High-speedEMUs Curve-passing Performance
In order to study the influence of the torsional mode, bending mode and umbrella mode of the wheelsets on the vehicle curvepassingperformance, the vehicle-track system dynamics models were established, in which, the wheelsets structures were considered as rigidbody and flexible body respectively.

| description | In order to study the influence of the torsional mode, bending mode and umbrella mode of the wheelsets on the vehicle curvepassingperformance, the vehicle-track system dynamics models were established, in which, the wheelsets structures were considered as rigidbody and flexible body respectively. The curve-passing performance of the vehicle was assessed by the vertical wheel rail force, lateralwheelset force, derailment coefficient and the dynamic wheel load reduction rate according to UIC518. The results showed: The 1st bendingeigen modes had the largest effect on the vehicle curve-passing performance, and indicators of the curving performance increased with thedecreasing eigen frequencies of the wheelset eigen modes. The ratios of the vertical wheel rail force, lateral wheelset force, derailmentcoefficient and the dynamic wheel load reduction rate of the flexible wheelset model to the rigid wheelset model were 1.010, 1.167, 1.241 and1.033 respectively when the eigen frequency of the 1st torsion eigen mode, 1st symmetric and antisymmetric bending eigen modes were 46 Hz,62 Hz and 128 Hz. The wheelset structural flexibility distinctly influenced the lateral wheelset force and the derailment coefficient. |
