Alcoa Airplane Bearing Bracket · 模型 308381
Presented model is a modified version of the original model. Received only by removal of material without adding material. Thus, ensure entry of a new geometry in the range of the original geometry. In preliminary analysis of the model, it is noticeable that the loads, regardless of their direction, strictly act only in the plane XY. In course of construction engineering it is known that the optimal cross section for the flat load is section of the I-beam. Therefore, when construction the new geometry, I have observed this condition. The volume of the original model (no bearings) is 109674.75 mm ^ 3, and the optimized 54152.44 mm ^ 3, which represents 50.62% weight loss. Achieved form is simple to manufacture, without small items complicating printing. Transitions between internal surfaces are filleted to avoid the concentration of stresses. Performed FEA analysis COSMOSWORKS. Results for the three load cases shows stress about the yield stress. If necessary extra safety factor, the walls of the body may be slightly thick, to achieve the desired result. Shown solution is only a concept. Of course, could add fillets and openings, but I fear that they only complicated geometry without notably reducing the volume and increase strength. Moreover, the purpose of this detail is to do a job, not to serve as ornament :)
