Task description

Students are required to carry out a design audit on a weld group of their choosing that is subject to fatigue loading. The welded joint should be connecting steel or aluminium components (aluminium requires different SN treatment), and analysis should be possible using the techniques developed in EGB316 classes. Also, you must be able to measure all weld group and key system dimensions and approximate/calculate/determine the working loads (application location, direction, magnitude, etc.).

You can choose a welded connection from a machine you are familiar with or some other machine you have access to. The system CANNOT be akin to any of the systems analysed in the lectures (i.e. not a patient lifter or like any design workshops etc.). The main requisite is to investigate a real machine and make design decisionsi/ engineering judgements regarding properties, forces etc. and determine if the welds are safe. This designation could be done by leaving weld size or material unknown and evaluating one or other using the analysis procedure developed in class, or you could measure/determine/estimate/research all necessary values and establish a factor of safety from the analysis procedure. Either approach will allow you to make conclusions on the safety of the existing welded arrangement, and the appropriateness of any and all loading and system assumptions you have made. The analysis must be based on fatigue loading, and the calculations will be both hand calculations and ANSYS analysis.

Detailed technical drawings of the welded component are also to be produced using Solidworks or equivalent professional solid modelling package (refer to CRA).
