摘要
以卡塞格林望远镜系统结构为研究对象,利用有限元分析软件ANSYS,对其结构进行静力和模态分析,研究系统结构的整体偏移和固有振动频率。检验出不满足设计要求的方案,并针对其不完善之处,提出新方案,最后通过有限元分析结果对比来进行选优,为整个望远镜的结构设计提供了可靠的依据。
We take the Casey Green telescope system structure as researching object.By using the finite element analysis software ANSYS,we do research on the structure analysis of static and modal,and make out the system structure of the whole excursion and inherent frequency.Then we inspect out which do not meet the requirement of design scheme and come up with the new schemes for the imperfect place.Finally,optimum choice is given based on the finite element analysis results.So this conclusion provides the reliable basis for the entire telescope structure design.
