| 英文摘要 | The centrifugal casting technology of large aperture aspherical mirror is studied for the centrifugal casting experiment of aspherical mirror in the laboratory environment, and the feasibility of the method is verified. A 1:80 scale experimental machine was designed by studying the similarity criterion of temperature field and the matching method of scaled model parameters in the centrifugal casting process of large aperture aspherical mirror, and the physical simulation experiment was carried out. The temperature field, stress field and final surface shape deviation of mirror were measured. The experimental results are compared with the simulated results. The relative error between the measured and simulated temperatures of temperature field is between 1.0% and 1.4%. The maximum compressive stress is reduced to 0.98 MPa when the aspherical mirror is properly insulated near tg. The measured surface shape deviation of aspherical mirror is -83.823 3 m, which is consistent with the simulated result. The non-observable parts in the process of centrifugal casting can be studied through simulation and experiment. 2018, Editorial Board of Acta Armamentarii. All right reserved. |
