초록
This paper deals with the calculation of contact resistance depending on the applied force by modeling surface roughness. The true contact surface area is made up of many asperities of varying heights which is close to Gaussian distribution. The mean square deviation and the mean value of the Gaussian distributed asperity heights were determined in this paper. The elastic deformation of the surface asperities according to the increasing of applied force were considered. The contact resistance was also calculated by using the Greenwood analysis.
