In this paper we describe two special finite element types for the modelling of rolling contact. The first element is a disk bounded by a sharp edge which can roll over a smooth threedimensional surface. This element models the rolling contact phenomena of pneumatic tires that support road vehicles. The second finite element describes the kinematic contact between two arbitrary three-dimensional bodies with smooth bounded surfaces. In particular the higher kinematic pair of a wheel and rail as can be found in railway vehicles is analysed. Both element types are incorporated in a general multibody dynamics software package that handles the modelling of the other rigid or flexible bodies in the system and their interconnections. The disk element is illustrated in the stability analysis of the rectilinear motion of a rolling disk. Two tests on a single wheelset moving an a tangent track illustrate the use of the wheel-rail contact element. |
