Abstract

present, an unprecedented development situation of the urban rail and traffic engineering is presented. Bearing as a key component of vehicle operation safety, its performances and reliability should achieve higher requirements. Because the number of characteristi c data of bearing performances is small and prior information on probability distributions and trends is poor, statistics has difficulty in assessing the bearing performance. In order to study the nonlinear dynamic characteristics of rolling bearing performances, a unified representation of variable uncertainty and function polytrope characteristics of rolling bearing performances are proposed in information-poor relation space, which reveals its evolvement rule of nonlinear dynamic characteristics. The development of bearing technology for the urban rail and traffic Engineering should comply with safe operation, high speed, a longer maintenance period and the excellent running comfort.
