APPLYING INVERSE METHOD FOR HEAT TRANSFER OF HIGH SPEED SPINDLE

Abstract

This paper presents an inverse method for finding quantity of heat sources in high speed spindle. A commercialANSYS software and Conjugate Gradient optimization method are used to construct the proposed inverse method. Simulations for different number of measurementpoints andlocations are performed.These results show that excellent estimation on heat generation can be obtained through using only two measurement points.The current methodology will provide a useful tool to investigate the complex heat transfer process in the high speed spindle.
