Topography Optimization and Parametric Analysis of Bead Layout for Sheet Metal Bracket 2010-01-0266

Bracket can be reinforced through laying out beads without increasing its thickness, resulting in a lower material cost. To get the optimal layout of bracket beads, beads parameters are discussed through a typical design case. The ways of specifying bead parameters are given, such as beads height and width, by calculating and optimizing geometric parameters of bead section. Then, topography optimization has been applied to get the bracket beads layout. Designers can get the best bracket beads layout through topography optimization software. For improving the first natural frequency of an automotive DVD bracket assembly as an example, the detailed topography optimization process is described and the beads of the DVD bracket are laid out through the method. After being optimized, the first natural frequency of the DVD bracket assembly is increased 30%. The process of beads development can be optimized and the design cycle can be shortened through the methods used in the bracket bead design.
