(2006). Fatigue results has been evaluated as shown the Figure 7: (a).Stress plot (b). Deformation plot (c). Fatigue life plot (d). Factor safety plot (e). Factor safety plot . as the fatigue life is minimum of 8.69E6 and Fatigue factor safety is 1.59 for the existing housing bracket weight of 1070 grams.

Existing housing bracket stress and fatigue analysis results are used for the realistic target setting for the optimization as to reduce weight of minimum 100 grams and maintain the fatigue factor safety to 1.5. Keeping these as a constraints the housing bracket was looked for the weight reduction without disturbing the strength factor. The weight optimization possibility has been explored as shown and modified the existing housing bracket for the lesser weight of 886 grams with optimization methods references by Robinson Larson (2017).
