Longitudinal effects and bending of the statically uncertainty beam under elliptic puanson

In paper the method to study of the tensiled and bending beam with fixed ends performed, bending under the puanson is elliptic. As a result of investigation of the contact was found out that there is a gap between beam and puanson (contact appears only in two points) in case when beam’s ends have an longitudinal degree of freedom. To embody contact on whole length the beam should be compressed in longitudinal direction. As example we had calculations of the contact behavior in hyperboloid connector of radio electronic equipment of aircrafts. Wires of a hyperboloid connector are angle oriented (to the axes of plug) beams, and have fixed ends. Pressure on beams will be elliptic. Proposed method allows to calculate magnitude and area of contact pressure, maximum stress and longitudinal force in wire. Preliminary longitudinal tensile was recommended. In this case reliability of the connection will be increased.
