摘要

为了研究离心熔铸反射镜制造技术中热历史状态（成型温度及冷却速度）对成型效果的影响，采用有限元分析软件Abaqus对不同的成型温度及冷却速率进行仿真分析，确定成型温度为950℃、冷却速率为1℃/s时可以完成反射镜在模具中的充模和成型；之后进行离心熔铸试验并对成型结果进行测量。在冷却速度大于1℃/s时，反射镜由于冷却后局部残余应力过大，导致其发生碎裂。同时通过对仿真结果、理论计算结果以及试验结果的分析对比，得到反射镜边缘的轴向高度与理论值相差10.12 mm，具有较大的面型误差，产生面型误差的原因是由于在高温成型冷却后反射镜体积收缩导致面型发生变化。

Abstract

This study investigates the influence of thermal history (molding temperature and cooling rate) on the mirror forming process for spin-cast aspheric mirrors. Abaqus finite element analysis software using different molding temperature and cooling rate of simulation analysis to determine the Spin-cast temperature is 950℃ and the cooling rate of mirror is 1℃/s which can be completed in the mold filling and mirror forming. The spin-cast experiment was executed

and the forming results were measured. When the cooling rate is more than 1℃/s

the mirror is fragmented owing to the excessive local residual stress after cooling. Additionally

the axial height of the mirror edge differs from the theoretical value by 10.12 mm

and there is a large surface figure error. This surface figure error is attributable to the volume change on cooling.
