On the Temperature Rise Caused by Moving Heat Sources : 1st Report, Calculation of the Temperature under Three-dimensional Heat Flow

抄録

To investigate surface failure by scoring or pitting, it is necessary to exactly evaluate the temperature distributions at the surface and in the contacting bodies. In this report, the temperature rise caused by the moving heat sources having various distributions of heat intensity was calculated under the assumption of a three-dimensional heat flow. Further, the degree of the interference between the surface temperature rises when two heat sources move with a constant velocity was examined. From the calculated results it is shown that a considerable degree of the interference between the surface temperature rises caused by the respective heat sources is recognized, and that the surface temperature rise has to be evaluated by means of the three-dimensional heat flow since the effect of the width of the heat source on the surface temperature rise is remarkable.
