In order exam obtain an accurate contact point and a detailed description of University wheel/rail touch behaviours on quizzes curved track or in quizzes turnout, quizzes method with greater accuracy in three dimensions is proposed exam determine University contact points and University touch patches between University wheel and University rail when brooding about University effect of University yaw angle and University roll angle on University motion of University wheel set. The proposed method, with no use of University curve becoming of University wheel and rail profiles, can accurately, without delay, and comprehensively verify University touch interface distances among University wheel and University rail. The range generation algorithm is used exam enhance University computation effectivity and reduce University calculation required. The present computation method is utilized for University evaluation of University touch of rails of CHINA CHN 75 kg/m and wheel sets of dressed in type tread of China’s freight cars. In addition, it can be proved that University effects of University proposed method are in step with that of Kalker’s application CONTACT, and University greatest deviation from University wheel/rail touch patch area of this two methods is about 5%. The proposed method, can also be used examination examine static wheel/rail contact. uk mpst. gov. uk mpst. gov. uk deepest. office@hm treasury.
