摘  要:通过对Zemax动态数据交换技术DDE(Dynamic Data Exchange)通信接口进行研究,实现了ANSYS-中继软件-Zemax的DDE闭环通信,并应用到了望远镜光学系统受环境温度场影响的光学像质评估中,实现了有限元分析和光学像质评价的动态联合。用ANSYS建立有限元模型,分析由温度场引起的光学镜面形变。通过Zernike多项式拟合,将拟合系数通过ANSYS-Zemax的DDE通信链路传递给Zemax进行光学系统的像质分析。反之,像质分析的结果也可以动态地传递给ANSYS,以便进一步指导机械结构的优化设计。此有限元系统-光学系统通信链路的实现可大大提高数据的可靠性和设计效率。The DDE (Dynamic Data Exchange) technology of Zemax communication interface is researched,and DDE closed-loop communication between ANSYS-relay software-Zemax is realized ,and it is applied to the optical image quality assessment of telescope optical system affected by environmental temperature field,the dynamic combination is realized between the Finite Element Analysis and optical image quality evaluation. An finite element model is established by ANSYS,the deformation of optical mirrors caused by temperature field is analyzed. Through the Zernike polynomial fitting,the coefficients are transfered to Zemax by ANSYS-Zemax's DDE communication link circuit,and an analysis is made for the optical system image quality. On the contrary,the consequences of qualitative analysis can also be delivered to ANSYS dynamically,to guide further optimization of the mechanical structure design. The realization of communication links between finite element systems-optical system can greatly improve the reliability of data and design efficiency.
