How to calculate the force and length on gas strut/gas spring?

Calculating the length and force of a gas strut involves understanding the physical characteristics of the strut, such as its extended and compressed lengths, as well as its desired application and load requirements. Gas struts are commonly used in applications like automotive hoods, cabinets, and machinery to provide controlled motion and support.

Door Gas Strut
1. Weight of the object: Determine the weight of the object that the gas strut will be supporting.
 
2. Mounting position: Decide on the mounting position of the gas strut, as this will affect the effective length and force required.
 
3. Required opening angle: Determine the angle at which the object needs to be opened or supported.
 
4.Once you have these factors, you can use the following formulas to calculate the gas strut length and force:
 
Gas Strut Length:
L = (h + s) / cos(θ)
 
Where:
L = Gas strut length
h = Height of the object
s = Distance from the hinge to the gas strut mounting point
θ = Opening angle
 
Gas Strut Force:
F = (W * L) / (2 * sin(θ))
 
Where:
F = Gas strut force
W = Weight of the object
L = Gas strut length
θ = Opening angle
5. Selecting the Gas Strut:
- Choose a gas strut with an extended length that matches or exceeds the calculated extended length.
- Select a gas strut with a force rating equal to or slightly higher than the calculated force requirement.
By using these formulas and plugging in the appropriate values, you can calculate the gas strut length and force required for your specific application.
