采用径向转向架的大轴重内燃机车曲线通过研究
Research on Curve Passing of Large Axle-load Diesel Locomotive with Radial Bogie
摘要
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.关键词
