摘　　要：挠性支承是快速反射镜的关键部件,介绍快速反射镜挠性支承的运动学设计。根据约束和自由度的空间关系确定挠性支承的约束和自由度模式,利用细杆作为约束元件构造4种快速反射镜挠性支承,并以此为依据对现有快速反射镜机构进行分类,获得两种新型挠性支承结构。研究结果可为机构选型、优化和工程设计提供指导和依据。The flexible support is the key component of fast steering mirror.The kinematic design of flexible support for fast steering mirror was introduced.According to the spatial relationship between constraints and degree of freedom,the mode of constraints and degree of freedom of flexible support was determined.The slender rod was used as the constraint element to construct four configurations of flexible support for fast steering mirror,and two new types of flexible support structures were obtained based on the classification of existing fast steering mirror mechanisms.The research results can provide guidance and basis for mechanism selection,optimization and engineering design.
