Defining the Design Study Variable

You define the spring constant as a parameter, and you add it as a variable in the design study.

1. Create a new Design Study.
2. On the Variable View tab, expand Variables, and select Add Parameter. In the Parameters dialog box:
   1. Under Name, type a name for the parameter, i.e. Spring_Constant.
   2. Under Category, select Motion.
   3. In the Motion study tree, double-click LinearSpring2.

      The spring feature is highlighted in Item Selection, and all available components are listed in Component Link.

   4. Select the component Spring Constant (Spring) to link to the parameter.
   5. For Value, type 17500.
   6. Click Apply and OK.

      An asterisk under Linked shows that the selected component is now linked to the parameter.

3. Add the parameter under Variables.
4. Select Range with step. For Min, type 17400 (N/m), for Max, type 17600 (N/m), for Step, type 25 (N/m).
