Discussion Overview

The discussion centers on calculating the lateral load applied to a pneumatic cylinder during operation, particularly in relation to a specific force and its impact on the system's design. The scope includes technical reasoning and application considerations in engineering design.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant notes that a 6N force applied at the base will create a bending moment in the piston rod, suggesting that alignment of forces with the rods is crucial for optimal performance.
  • Another participant expresses the need to determine the lateral load exerted by the 6N force, indicating that the pneumatic cylinder has a specified allowable lateral load of 0.4N at full stroke.
  • A later reply calculates a lateral load of 12.9N at a distance of 10mm from the base of the cylinder, implying that if the force's position cannot be adjusted, a redesign may be necessary.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of the current design given the lateral load implications, with no consensus reached on the best approach to resolve the issue.

Contextual Notes

Participants mention specific values and conditions, such as the allowable lateral load and the force applied, but do not resolve the mathematical steps or assumptions involved in the calculations.

Hi Everyone,

Trying to figure out the lateral load, applied to a cylinder I'm trying to use, during operation.

Heres a quick dragram:

If you could show me how this is done I would be very grateful, It looks like it should be really simple, but I just can't seem to get my head around it.

Thanks!

The 6N force applied at the base is going to create a bending moment in the piston rod. Pistons in cylinders work best when the forces are aligned with the rods, not offset as is shown.
 
Thanks for the reply.

I know it isn't ideal, but, if possible, it would be the best solution in my application.

The pneumatic cylinder I'm trying to use has an allowable lateral load of 0.4N at full stroke, so I would really like to be able to find out how much lateral load 6N at that point would exert.

When I get back in the office I will stick it in Creo Simulate, but until them I am having to rely on my brain, which seems to be failing me. :smile:
 
Just looking at the moment arms, a lateral load of 12.9 N @ 10 mm from the base of the cylinder is what you are looking at. If the relative positions of the 6 N force and the cylinder can't be altered, then a different design is called for.
