旋转双棱镜伺服驱动装置设计与分析OA

Aiming at the problem that it is difficult to achieve a new breakthrough in the traditional platform-based optical-mechanical system research,a rotating biprism device is designed Through the mechanism of rotating biprism is studied,and its anti-shock and vibration characteristics are simulated and analyzed by Ansys.The servo drive scheme of the double prism device is given,and the simulation calculation is carried out.Three closed-loop PID controller is designed to realize the independent action of the eyepiece and the objective lens.By building a real test platform,the double prism servo control test is carried out.The results show that the design can accurately drive the eyepiece unit and the objective lens unit of the rotating biprism to rotate independently according to the requirements of the upper command,and the test results are good.
