The Design of Optomechanical for Bear Severe Mechanics Environment

摘要

Optical lenses act as the important methods for acquire the image information is applied increasingly board ,In accordance with the application environment that require content the precision and the force environment adaptation yet more power, so it is necessary that research on the adaption ability to the big level vibration and shock. In order to stand the bitter force environment put to use the centering assembly technology to ensure the image quality of the optical system. Design the different damping coefficient rubber-bearing isolation that assimilate the big level shock energy. At first, by the Pro/e software establish the three-dimensional model and use the ANSYS software simulate and analysis the result of the design. We want to apple the Sigfit software to simulate the effect that the vibration and shock affect on the MTF of the optical system. After optimize the design theory so as to attain the optimized result. By the experiment test the lenses about the accommodate ability, the result which can meet the shock of5000g.and 20g random vibration, camera can work effectively. This kind of design technology is mature and reliable and live through the examination under all kinds of environment, this design method is provided the reference for the design and development of optical mechanism production.
