Design optimization is a process based on the finite element method for the shaping of technical components, for the use of which complex software and hardware is necessary. From a mathematical point of view, it is an optimization problem .

Goal setting

The purpose of the design optimization is to better adapt the shape of a component to the technical requirements; the optimization can serve, for example, to minimize the material consumption for a workpiece with the same benefit. Conversely, the technical benefit can also be maximized with a given material input.

Example of nature

The environment provides many examples of design optimization, evolution ensures a slow but continuous optimization in form and function. With trees, design optimization can be observed in just one generation. Due to external influences, such as a static load from the wind , the tree changes its external shape, so that the stresses in its trunk are minimized. Another example is bone remodeling around implants , which is also carried out according to biomechanical principles. These observations are transferred to a technical model for design optimization.

method

The optimization begins with a rough design proposal with a known bearing, load and given limit dimensions. This object is modeled for the finite element method and the corresponding stress curve is then determined. With the help of the appropriate software , material is now virtually reduced in unloaded areas of the component or added to heavily loaded areas. After a certain number of iterations , a shape-optimized component emerges.
