The bolt is observed as a body of rotation. Force distribution and contact pressure in a bolt screw joint with a flange, bolt head with a flange and flanges among themselves are defined by the solution of three Hertzian problems with the finite-element method. The proposed methods allows solving problems of bolt bond strength taking into account pretension load magnitude, contact interaction of constituent elements of power hardware and radius under bolt head, that is defining for correct problem solving high-cycle fatigue and life time of bolt-joints. Application - power machine building. Product Description popup.authors popup.nrat_date 2020-04-02 Close
