straight wheel
2.Over the years, obsorbing the advanced technology, the Association has developed the straight line drawing machines, wet drawing machines, upside down style wire drawing machines, spool take-up, pay-off unit, wheel heat treating winder, heat treatment take-up, pay-off unit, strander machines, pre-treatment line machines.
3.In this paper the program based on trace line method is used for the wheel rail space dynamic contact geometry relationship, some analysis and comparison of geometrical contact states between the different wear type treads and rails interactions are given, considered of the lateral section curvature radius and equivalent taper, the abilities in contact stress, the critical speed in straight line, and curve negociation performance are discussed.
