Modelling and Analysis of Static and Dynamic of Connecting Lugs and Mechanical Bracket using Abaqus

This thesis contains the determination of static stress and displacement analysis of connecting lug of given load of 50 Mpa and the natural vibration analysis of mechanical bracket. Which has got a wide range of applications, such as connecting lugs are used in aero-heavy engineering industry to transfer the load from one component to another component. Connecting lugs are widely used to connect major aircraft components. Such joints are characterized by 100% load transfer through a pin or a bolt. This design offers several advantages over other solutions namely, simplicity, ease of assembly and free pivoting around the pin axis. A mechanical bracket for mounting a telecommunication antenna on a metallic tower comprises a pipe section to secure the bracket to the tower. The angular position of the pipe section about its longitudinal axis is selected to appropriately orient the bracket. A transversal pivot bridges a pair of spaced apart parallel plates of the bracket. The antenna comprises a pole member with a free end pivotally mounted on the pivot between the two plates. A bolt and nut assembly traverses the pole member and two accurate slots respectively made in the parallel plates, and hence the problem is selected.
