概要

論文の詳細を見る
All degrees of freedom (especially wheel-axle rotation), Kalker's program 'FASTSIM' which considers spin creepage, and variation of contact ellipse were newly introduced for curving simulation of a roller-type pendulum vehicle. Digital simulations of curving for a representative example were made and the influence of newly introduced factors were studied. It was shown that wheel-axle rotation decreased lateral wheel-rail force by 8% (for steady value without track irregularity), by 5% (for maximum value with track irregularity) and changed wheel load by 1% (for steady value), by 5% (for minimum value). It was also shown that spin creepage increased lateral wheel-rail force by 19% (for steady value), by 7% (for maximum value), and variation of contact ellipse decreased lateral wheel-rail force by 8% (for steady value), by 4% (for maximum value). Spin creepage and variation of contact ellipse had little effect on wheel load.
