摘　　要：为了提高多工况下光学镜面仿真及面形拟合的工作效率,作者基于VS进行模块化的二次开发工作。依次完成了基于ANSYS软件APDL参数化命令完成多工况拟合及数据结果输出功能,基于VS软件对特定面形拟合的控制计算功能程序和对结果文件的结果整理功能程序,后两个程序分别形成各自的可执行程序,并在ANSYS中予以调用。最后基于上述二次开发软件对某光机系统三镜及其支撑结构进行应用化实例验证。计算结果表明,三镜镜面面形拟合结果RMS=2.792 nm,满足设计指标要求,同时二次开发软件达到预期工作目标。花费在多工况设置、面形拟合、结果处理全过程的时间大幅度减少。对于三镜支撑结构设计工作而言,单次多工况计算节省30 min以上。验证本二次开发在迭代设计过程中具有提高工作效率的作用。In order to improve the efficiency of optical mirror simulation and surface fitting under multiple working conditions,modular secondary development is carried out based on VS.Based on ANSYS software APDL parametric command,the function of multi-working condition fitting and data result output is completed.Based on the development of VS to complete the specific surface fitting software control calculation function program and the results of the document collation function program.The latter two programs form their own enforceable programs and call them in ANSYS.Finally,based on the above-mentioned secondary development software,three-mirror and its supporting structure are verified.The calculation results show that the fitting results of three-mirror mirror surface RMS=2.792 nm,meet the requirements of the design index.At the same time,the software based on secondary development achieves the expected work goal.Cost in multi-working setting,surface fitting,resulting in a significant reduction in processing time.For the design of three-mirror support structure,the single multi-working condition calculation saves more than 30 minutes.It is verified that the secondary development can improve the work efficiency in the iterative design process.
