Abstract

Riveted joints are widely used for fastening sheet metal components. Cylindrical rivets are generally preferred but due to space constraints in some cases, other geometries are being explored. In this work, a practical case of a rectangular riveted assembly for back plate of pendulum absorber assembly commonly used in modern vehicles for damping secondary vibrations is considered and an iterative simulation study for design optimization has been conducted using finite element based software FORGE for the riveting process. Efficacy of riveted joints is analyzed in terms of Von-Mises stresses, tonnage and contact pressure. Out of the many design parameters, only prominent parameters like variation of fillet radius in the plate hole and rivet and the distance between the hole and the side of the plate were concentrated upon. An attempt is made to change the values of these design parameters to arrive at an optimum design criterion for the riveted joint so that the stress induced is minimized to a value that can be considered to be within permissible limits. It is found out by iterative simulation studies that the maximum stress induced got reduced by 23.2% with a square rivet as compared to a rectangular rivet.Keywords: Rectangular riveted assembly, FE software FORGE, design parameters, simulation studies Cite this Article Ratnadeep Bhattacharjee, Madhu Murthy K, Amba Prasad Rao G.
