| Abstract |
We present an overview of the engineering design of stressed lap developed at Nanjing Institute of Astronomical Optics & Technology. Stressed lap consists of two parts: active deformable lap, driving-adjusting mechanism. The finite element model for active deformable lap is constructed, and the performance of lap deforming is discussed. Descriptions about mechanical structure of driving-adjusting mechanism are given. Now, stressed-lap polishing tool has been used to accomplish a fast parabolic mirror in Nanjing. The φ910mm F/2 parabolic mirror has been figured to an accuracy of 22 nm . |
