The model and its governing equations for a starting process are presented. Taking the plane contact pair as an example, many simplified numerical solutions are obtained. A good agreement between he solutions and the experiments made by others is found so that an important theoretical basis is provided for studying the starting process in transient process. Two imoportant parameters to evaluate the starting process are introduced: tcr, the transitional time of lubrication state, and tf, the time to establish...

Two imoportant parameters to evaluate the starting process are introduced: tcr, the transitional time of lubrication state, and tf, the time to establish oilfilm. The effects of both waviness and roughness on the tcr and if are studied.

The effects of roller profiles on contact pressure distribution have been discussed with numerical solution based on the influence coefficient method. The problems of the contact singularity and pressure concentration in elastic line contact of finite length are described.It has been clearly shown that the singularity must be precluded and the pressure concentration should be decreased in the design of profiled rollers. It has been demonstrated that the Lundberg's logarithmic profile is an optimal one for the selection of roller profiles. The size of the crown should be determined by operating conditions. Results of computation and analysis are suitable for other machine elements in which the line contact interface is included, as gears, cam-tappet, etc.

Collecting ring is an intermediate device through which the electric signal is transferred when making measurement on rotary object, so that the performance of collecting ring will direct effect the measurement accuracy. The main performance of brush collecting ring is the variance of contact resistance between brush and ring. Experiments and research on this have been done by authors recently. Up till now the variance of contact resistance between brush and ring can be controlled less than 8 ×105Ω.
