FEA - Assignment ExampleThe results ar then used to undertake weighting optimisation of the model. The limits of the redesigned model are the face attitude the reduce, strength of the load and the fixed points which are non alterable. The only changing variables are the geometry and frameworks used.The model was then analysed in the SimulationXpress Analysis Wizard. The first step in this process was to fix the position of the 4 holes where the bracket will be fastened to the body of the structure. This is carried step to the fore in the fixtures partition and the faces assigned as fixed geometry as shown in figure 2. This fixes the lower section of the bracket to its location in the machine, structure or component where it will be employed.The external load on the geometry is a force of 1kN and is applied on the locality of 750and 50mm from the speeding section of the load bearing face. This force does not act on the whole region hence a sketch is created 50mm from the uppe r section and creating a split line to allow the force to applied on the hatched region of the load bearing face on the drawing. Figure 3 shows the model with the split line created.The pretense results are produced giving the stress, displacement, deformation and the safety factor. Determining the maximum displacement and stress is the key documentary at this point. The maximum Von Misses stress is 737.96mPa while the give up stress is 620.422mPa. This shows that the stress experienced is higher than the yield stress and hence failure due to the 1KN load applied. This is shown in figure 5.The results from part A are used to carry out a redesign of the bracket which are then validated with mortal Element Analysis. The main objective of this redesign work is to reduce the weight of the bracket by at least 10% and the deflection should not be more than 10%.In this redesign work, the material was the main focus for reducing the weight of the bracket. The aim was to select a materia l similar to sword but is lighter in weight. Aluminium
