The fixture that supports the binocular telescope should be highly precise. However, its thin and aluminum-alloy-made structure will reduce the strength and stiffness, which may result in deformations during the machining process. This, together with the complicated structure of the body, makes it difficult to determine the concrete positions of maximum stress and maximum deformation through traditional calculation methods. Therefore, Patran software is employed in the paper for pre-treatment and post-treatment, and Nastran software employed for analysis and calculation so as to analyze and optimize the stressed deformation of the workpiece in the fixture. |
