Elastic bend of twisted waveguide

Abstract

The construction of any antenna-feeder system, in addition to providing radio technical parameters, must has the specified strength and rigidity under operational loads. This paper considers the stress and deflection of a twisted waveguide at bending as the most common and dangerous type of loading. According to the technical theory of beams, obtained equations which describing the integral characteristics of the across section as well as stresses and deflections of the twisted waveguide. It is shown that in calculating the twisted waveguide strength and stiffness, it is necessary to apply minimum values for integral characteristics of the cross section regardless of the load direction.
