Cabinet with doors lifted by a gas spring

    Gas Spring
AI Thread Summary
Calculating gas springs for cabinet doors that lift rather than hinge requires understanding the mechanics of a four-bar linkage system. A sketch illustrating the door's support in various positions can clarify the mechanism's operation. The force needed for equilibrium at any door position can be determined through established analysis methods found in textbooks on Theory of Machines. Helpful software for gas spring calculations includes JGC software, though guidance on downloading or purchasing it is needed. This foundational knowledge will assist in selecting the appropriate gas spring for the application.

Hello everybody.

I'm trying to figure out how to calculate gas springs for specific doors not with hinge, but lifted up, like on the picture.
Do anybody experience with such type of mechanism?

Also I'm looking for helpful software, for gas spring calculation (different types). I found screens from JGC software, but I don't know how to download or buy it.

The photo you show does not make the mechanism clear. Try posting a sketch that shows how the doors are supported at about the half open position.

OK, here is draft of mechanism. Cabinet closed, during opening and fully open.

The linkage is just a four bar linkage, with the gas cylinder added to provide motive power. The analysis of the four bar linkage is given in many textbooks on Theory of Machines. With that sort of analysis in hand, you can calculate the force required for equilibrium at any position; that is the force that you would ideally want the gas spring to provide. That should get you started.

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
