Application Area 4: Parameter Identification

Optimization can also be used to determine the required values for spring and damping constants. The example below illustrates a common scenario.

A simple spring mass system is defined. A force of 1N acts on Body-1 and a force of 2N acts on Body-2.

Figure 1.
Design Objective
Compute k1 and k2 such that spring 1 deflects by 3mm and spring 2 deflects by 4mm when a static analysis is done.
Design Variables
The spring stiffnesses k1 and k2.
