Calculation of Equal Resistance Riveted Joint

Abstract

Rivet joints are used in structures that can withstand large vibration and repeated loads, as well as for connecting parts made of non-weldable materials and not allowing welding due toheating parts. In addition, riveted connections widely used to connect seversl parts in one package. In instrument making, rivet connections are used more often than in mechanical engineering. Among all constructions applied in the technique, constructions with equal resistance are considered optimal. Thus, equal stresses are created in any element of these constructions and even at any point of each element. When the value of these stresses is equal to the allowable stress, the mass of the structure is minimal. With a theoretically correct choice of the optimal elements of the connection, its destruction should occur along all of the above sections simultaneously. Riveted connections must be of equal strength. This means that the calculation must ensure the strength of the rivets against shear and crushing, the walls of the holes for the rivets-against crushing, thr parts connected along weakened sections-against tension, and their edges-against shear (puncture). The issue of design of riveted joint with equal resistance is considered. A formula has been obtained that indicates that the diameter of the rivet depends on the thickness, width and number of rivets of the connected parts (sheets).
