    Gas Spring
AI Thread Summary
The discussion centers on the search for an adjustable gas spring that can be modified automatically during operation, allowing for both pressure release and gas injection. Current options primarily involve manual gas release, which does not meet the user's needs for automation. A comparison is made to linear actuators controlled by solenoid-operated directional valves, suggesting a potential solution. However, concerns are raised about the inefficiency of such systems, as they only provide full and exhaust pressure. The conversation highlights a gap in the market for automated gas spring solutions.

Hey,

Has anyone heard of a gas spring that could be adjusted in mid operation? The gas could be released from the gas spring to decrease the pressure inside and alternatively gas could be injected by a compressor to increase the pressure in gas spring.

I have only found gas springs, in which the gas can be released. And this is typically achieved by manually releasing the gas. But I am looking a gas spring system that could be modified in an automated fashion.

Thanks!

Consider a typical linear actuator, (pneumatic cylinder), controlled by a directional valve, (maybe solenoid operated), with compressed gas from a pressure reservoir.

That appears to be what you are considering.

Such a system will be inefficient as only full pressure and exhaust pressure are available.

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below.

Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
