It is the combination of multi-point forming and traditional spinning. Principle of EST is described  and plastic deformation is generated  traditional spinning method is compared with it  experimental result accords with simulation result. Feasibility of EST is validated by simulation and experimental results. (2011) Trans Tech Publications.  and characteristics of it are analyzed. Finite element analysis (FEA) model of disc-shape part is established  EST process is analyzed  equivalent stress and plastic strain distributions are analyzed. EST equipment is developed  and the experiments are made.

The key technique takes advantage of deformation of ultra thin mirror as the influence of environment to adjust the surface figure. Its accuracy meets requirement. An analysis method is based on finite element analysis (FEA)  and many items  including the amount of support points  the way of arrangement  the optimum design of support component are studied. The finite element method was used to analyze the mirror and some different mirror support schemes. The principal aim of the mirror analysis is to get numbers of support points and the ways of the support. There are three schemes including 12-6-1  12-8-1 and 16-8-1 models. Deformation of deadweight is calculated under the three conditions. The way of 16-8-1 is more suitable than the designs of other two. The support subassembly is amended to meet with the mirror surface RMS in the range of 30m. Deformation of the mirror with support structure has been calculated. The result is 16.52nm  lower than a quarter of the wavelength  which indicates the feasibility of the support scheme applied to mirror. Theoretical result for the best way of support is presented. The result of analysis shows that requirement surface figure could be met through adjusting support points. It predicts feasibility of the support technique and provides theoretical value for active adjustment in the laboratory. At present  support and adjusting experiment of ultra thin mirror is being carried on.
