摘要
为探究径向转向架在33 t轴重内燃机车的可行性,从径向转向架的概念、结构和原理出发,为大轴重内燃机车提供了一种径向转向架方案.在多体动力学软件中建立动力学模型,对比研究了采用径向转向架和传统转向架的重载机车通过曲线时导向轮对的黏着系数、蠕滑率和磨耗功.通过计算分析发现,与传统转向架相比,径向转向架可以减少车轮的滑动量,提高机车通过曲线时的黏着利用率,降低轮轨磨耗和左右车轮的不一致磨耗,降低轮对镟修频率,该结论可为今后我国研制大轴重高黏着内燃机车提供一定参考.
Abstract
To investigate the feasibility of a radial bogie for 33 t axle-load diesel locomotives,a ra-dial bogie scheme for large-axle load diesel locomotive was designed based on the concept,structure,and principle of the radial bogie.A dynamics model was constructed in multi-body dynamics software,and the adhesion coefficients,creepages and wear power of the leading wheelset were compared for heavy duty locomotive with the radial bogie and the conventional bogie while passing the curves.Through calculation and analysis,it is found that compared with the conventional bogie,the radial bogie may decrease the wheel slip momentum,improve the adhesion availability of locomotive when passing curves,reduce the wheel-rail wear and inconsistent wear of the left and right wheels,and de-crease the frequency of wheelset repairs,which provides valuable insights for the development of large axle-load and high adhesion diesel locomotives.
