Multistudy Optimization of a Bracket

Application ID: 19761

In this shape optimization example, the mass of a bracket is minimized by changing the size and position of a number of geometrical objects.

The requirements give limits both on the lowest natural frequency, and on the maximum stress in a static load case. This means that results from two different study types must be used as constraints in the optimization problem. For the stress constraint, a maximum over the whole domain must be computed, since the location of the peak stress is unknown.

In addition, several geometrical constraints are required to maintain a feasible geometry.

This model example illustrates applications of this type that would nominally be built using the following products:
