Spring Hanger Design

[denisgomes]

Design and implement a hanger design algorithm which allows for different thermal conditions to be met and either hot or cold load balanced supports.

The algorithm

1. Turn spring into a Y supports and do dead weight analysis.

2. Add vertical force from (1) at spring location equal to load from (1) and do a thermal run. Note the weight from (1) is the dead weight that must be supported in the operating case. The spring is designed for this thermal case.

3. Use the displacement from (2) and the operating load to select a spring from a vendor catalog. (pick a stiffness from the charts provided)

4. Using the stiffness from (3) calculate the installation load (theoretical cold load) using the formulas for springs depending on F-type or not.
