installation and the following calculations concerning gas spring forces. Firstly you should decide whether the gas spring needs to open a flap or hatch auto-matically or just support a manual opening. Depending on the weight of the flap or hatch you need to calculate the horizontal position and several further positions. The
Define the gas spring placement or installation application. In this case, a set of two gas springs will be used to hold open an 8-foot-long, 6-foot-wide hinged hatch cover on a fishing boat. The cover weighs an evenly distributed 80 pounds.
Define the application. For example, if a pair of gas springs, one per side, will be used to hold up the 6-foot-long, 60-pound hard cover of a pickup truck bed, you can calculate the gas spring load at any point along the travel of the cover from fully closed to fully open.

If the gas spring was not used rod-down, the piston would not have to go through the oil at the end of the extension and no damping effect would occur. When this is not possible and the gas spring has to be used either rod-up or near horizontal, an oil chamber or a fully damped gas spring should be specified.
*NOTE: If you use two gas springs, divide the force in half. The optimal position for a gas spring is usually halfway between the hinge and the center of the object you are lifting (force should be approx. twice the weight of the lid).
Other calculation for gas spring. F1 = ((50 x 1.5) / (2 × 2 × 0.40) + 5) = 9.81 x 508N In this case, since the tolerance is +/- 50 N, we would recommend two 550N gas springs.

How to Calculate Gas Spring Load. Suppose the tops of both springs attach to the middle of the cover, 3 feet back from the cab. The cover tilts up at a 30-degree angle when fully open at the rear of the bed. Fully open, the cylinder is 30 inches long, and it pushes perpendicularly against the 30-degree open cover.
The oil used in the gas spring is also useful to obtain a high damping effect on the last few millimetres of the stroke. If the gas spring was not used rod-down, the piston would not have to go through the oil at the end of the extension and no damping effect would occur.

In general the length to choose for gas struts is about 55% of the height of the door you are trying to keep open. So if you have a door that is 1000mm in height a 550mm long gas strut would be about right. In simple terms we are talking half the door height plus a bit when determining optimal gas strut length.
Proper size and installation extend the life of gas springs and dampers. Gas springs help lift loads or open doors or lids.
Jun 11, 2009 Re: How to determine mounting gas springs. The weight of the window is needed, and I can measure the whole thing on a bath scale. Right now I know that 1/4" glass weighs 3 lbs/sq ft. Each windshield window will weigh less than 12 lbs. The smallest gas spring is 20 lbs so a single should work, but using two will spread the load when closing.
May 06, 2017 First you would need to know whether the piston is insulating or not. If no heat flows in or out, you get a different result than if everything stays at the same temperature. The idea would be to see how the pressures change when you displace the piston a small distance from equilibrium. From the
We produce Gas Struts in four different diameters Shaft size Tube size 6mm 8mm 10mm 14mm 15mm 18mm 21mm 28mm To calculate the size and the force of the Gas Strut you require for your application use the following guidelines.

Feb 27, 2011 I don't know about any tutorials for gas springs themselves, but I think that you could simulate the gas spring with a simple preloaded compression spring for working out your mechanism. I think it would be easiest and fastest to use Motion Simulation (whatever its actual name is) to work out the best attachment points and required spring forces.
I decided to buy gas springs (the retracting kind) to assist in closing the bed. Using the measurements from the picture, from what I understand, the calculation would be: force = 110*(35.8125)/11.4375 = 344.43. At this point, I was feeling pretty savvy and bought two springs that had 150 lbs of force, thinking this would be perfect.
