| 摘 要： | 以弧形刻刀刻划79g/mm的中阶梯衍射光栅为研究对象,基于滑移线场理论建立了光栅槽形隆起高度的数学模型,并以此分析出槽形隆起高度随主刃半径增大而降低的变化规律.在有限元软件DEFORM中建立了弧形刻刀刻划光栅的动态仿真模型,模拟出主刃圆弧半径参数对槽形隆起高度的影响规律,和理论分析一致.为弧形刻刀刻划中阶梯衍射光栅的机理和工艺研究奠定基础.

| Abstract: | Study the process of carving 79g/mm echelle diffraction grating with the circular graver.On the base of the slip-line field theory,the mathematical model of apophysis height of groove shape is established,and the regularity to change has been analysised.The height reduces with increasing main edge radius.The dynamic models of carving grating with the circular graver are setted up in the finite element software DEFORM.The variation of apophysis height has been simulated,consisted with the result of theoretic... |
