The effect of carbon fiber on sliding electrical contact property of copper-graphite composite materials has been studied.

5-MJ capacitor bank has been developed to investigate high-current high-velocity sliding electrical contacts.

In order to research the sliding electrical contact characteristics of Cu-base powder metallurgy strip under sliding electrical contact conditions,a lot of experiments were carried out with a self-developed high-performance sliding electrical contact testing instrument.

Finite element analysis of head/disk continuous sliding contact was performed to investigate temperature field and thermal stress field due to frictional heat using an axisymmetric thermal model.

In order to develop the critical operating conditions for demagnetization of the disk,a coupled temperature-displacement finite element analysis of a slider sliding contact with a textured disk surface was performed,so as to investigate simultaneously the stress and temperature distributions in the magnetic layer.

Also the stess distribution problem in the half space with gradient layers coating is considered and compared with the homogeneous half space and half space with single layer coating under same sliding contact load and in plastic deformation condition.
