【Abstract】 The HGD 81 A finite clement program for calculating heavy machine tool parts us used to analyse the distribution of heat source affecting the temprature gradient and thermal deformation of a vertical lathe column. The effects of temperature gradient and thermal deformation of several foreign and domestic made lathe columns of similar machine type under same heat circumstances have been analysed and calculated.更多还原
