Deformation analysis of the Kashima 34-m radio telescope is performed. Although the telescope has a large aperture and accurate reflector panels, the dish support structures determine the high-frequency performance. Especially in millimeter wavelength, deformations above 1-mm affect the telescope efficiency seriously. We have modeled 34-m telescopes into elements and used a finite element method FEM to simulate accurate telescope deformations. The first results we obtained agreed well with the realistic deformation. Future analysis and telescope evaluations based on computer simulations are possible with this FEM model.
