An Algorithm of Wheel/Rail Contact Geometry for Rigid Frog and Software Development
摘要
Abstract
Based on wheel/rail contact theory, an algorithm is proposed to obtain accurate wheel/rail contact parameters of rigid frogs and the corresponding software is developed in consideration of the change of complex railhead profiles and the discontinuity of gauge lines in rigid frogs. The LM wheel tread passing over No. 12 alloy steel combination frog is simulated by field test, and wheel/rail contact points along the longitudinal direction and key cross sections of frogs are measured and compared with those calculated by software. This software is used to analyze the influences on wheel/rail contact parameters when wing rails of cast manganese steel frog are heightened. The results show the variation regularities of wheel/rail contact points measured by field test agree with those of points calculated by software; the reasonable heightening of the wing rail can optimize the wheel/rail contact relationship and reduce vertical irregularities in rigid frogs, which validates the correctness of the algorithm and the feasibility of the software;the software is an accurate and efficient tool to optimize the design of wheel/rail contact relationship in the rigid frog zone.关键词
