Topography optimization helps manufacturers to design and optimize any thin-walled part. Like a drum skin, these thin sheet structures can be easily excited, causing undesirable noise, vibration and even damage under certain conditions.
To improve the vibration characteristics, local shape modifications such as beads are added for stiffness. Most of the time, the location, shape, and orientation of these beads is based on the natural geometry of the part and the designer’s experience. Topography optimization enables designers to define spaces where beads can and cannot be added, the width of the beads, as well as the draw direction, angle, and height. This means only practical designs are generated, with optimal patterns.
A software-optimized bead pattern will often dramatically outperform a traditional layout, maximizing stiffness, frequency response or other performance objectives – without adding mass or manufacturing complexity.
