摘　　要：背光板微阵列结构的自由曲面加工工艺较为复杂,目前加工策略较多,快刀伺服器加工是其中的策略之一,但利用压电陶瓷驱动快刀伺服器存在加工频率高与加工行程短的矛盾。分析了快刀伺服器的研究现状,建立二轴的快刀伺服器的结构,重点介绍了实现二维运动的方法,提出构建快刀伺服器在高频运动时获得大位移的拓朴结构实现方法,借助ANSYS分别从柔性铰链的材料、宽度、厚度等关键角度,不断优化其拓朴结构,获得适用于微纳加工的二轴的快刀伺服器,更加满足加工微阵列结构的自由曲面加工。The free surface processing of backlight board micro array structure is more complex.The current processing strategy is more,and the fast tool server(FTS)is one of the methods.But using the piezoelectric ceramics driving FTS,there is a conflict between high frequency and displacement in the machining operations.After analyzing the research status of FTS,this paper designs the 3D model of two axis FTS,and it focuses on the realization method of two-dimensional motion.The realization method is put forward to construct the topology of FTS to obtain the large displacement in the high frequency motion.With the help of ANSYS,it respectively optimizes the topology from the key point,such as material,the width,the thickness etc.By the above studying,it obtains the two axis FTS for micro nano processing to meet the free surface machining the micro array structure.
