| Abstract: | This article describes the static mechanical analysis of Shanghai 65-m diameter radio telescope azimuth track.The bending moment of the track and the stress of the foundation under loading are estimated using Winkler elastic ground-beam model.The contact stress between wheel and track is calculated according to Hertz theory.Thus it can provide the design basis to select the suitable track material and to make welding procedure. |
