| Abstract: | In this paper, a calculation method of affections caused by shear forces to the flexure deformation of a simple supported toothed beam was carried out from the formula of general displacements calculating. The main factors which affect the ratio of the deformation caused by shear forces to that of by the moments of the beam were analyzed: the tooth number, the tooth shape, the tooth depth, the ratio of span to depth of the beam and the load-bearing types. The affections are compared with that of a simple supported rectangular beam, which have constant depth. As a result, a brief computational method and several useful conclusions are derived. |
