Introduction to Variable Springs
Creating a vertical hanger with a variable spring
If this is your first time with Anvil Forgeworx Pro™, please see our Quickstart Documentation before proceeding.
All inputs will be made in the configurator screen; a walkthrough to this screen may be found here.
Lets start by creating the vertical hanger as in the hardware tutorial here.
- Select vertical hanger under support type
- Enter the overall assembly length - 144in
Under Support Data, enter the following values:
- Vertical movement - 1.25
Changing the vertical movement will produce a dynamic type support that is adjustable for the amount of movement. Any vertical movement from -4.81 to +4.81 will default to using springs, and any movement greater in either direction will default to a constant. As you increase the vertical movement, the spring will change through the different sizes to account for the distance of travel.
- Service temperature - 800
- Pipe size - 20
- Insulation thickness - 2
- Load - 6000
Under Support Options we can adjust the support variability so Forgeworx will return the correct size spring based on the movement and the calculated total travel.
- Support variability - 18
Your support should now look like this:
Open Support Assembly in parts tree on the left to configure the spring hanger.
In the properties menu on the right, the spring and hanger attachments can be manipulated to create your hanger. We will be adjusting the elevation of the spring and the spring hanger type.
- Spring elevation - 96in
The model now shows a type C spring held with a Fig. 290.
We will now change the type of the spring:
- Spring hanger type - A
You have now completed the variable spring tutorial.
