摘要: 本文考虑了旋转圆盘的厚度与温度分布的相互影响的条件下,直接引用文献[1]、[2]中的结果,并利用本文提出的一种迭代求解方法,求得了轴对称定常温度场中非均匀变厚度高速旋转圆盘的等强度厚度分布.Abstract: Considering the mutual interaction between the thickness of the disk and temperature distribution,and directly using results in [1],[2] and the iteration method suggested in this paper,we obtain the equi-strength thickness distribution of nonhomogeneous variable thickness high speed rotating disk under axisymmetrical steady temperature field.
