Topology Optimization of a Step Thrust Bearing

Application ID: 105861

In this tutorial model, a step thrust bearing is topology optimized to maximize the bearing capacity. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be spinning without any axial motion in the bearing.

The model shows that initializing the optimization with a nonuniform design, can result in local minima with a specific number of steps.

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