Abstract

The numerical analysis method for the surface deformation of rotating mirrors were presented based on the three-dimensional elastic mechanics and the computational techniques of finite element in this manuscript. With this method, the surface deformation curves of rotating mirrors including multi-surfaces from three to eight, aluminous, steel, and beryllium ones were calculated. A result was obtained that surface patterns of a mirror in operation are primarily dependent on the amount of surfaces and the axial hole which whether or not exists for aluminous and steel mirrors, but it rests with the amount of surfaces as well as Poisson's ratio for a beryllium mirror with so tiny Poisson's ratio. This conclusion is different from that of forerunner.
