| Abstract: | Through the mechanical analysis and calculation of the press-fitting process of the urban rail transit vehicle wheelset bearing,the theoretical curves of press-fitting force and journal displacement were obtained.Guided by the curve parameters demand,the press-fitting manufacturing methods of wheelset bearing was optimized,and a unified standard curve evaluation method for urban rail transit wheelset bearing was established.Through actual manufacturing application verification,the feasibility of the curve evaluation method was approved. |
