Calculate failure load on a locking pin

Click For Summary

Discussion Overview

The discussion revolves around the analysis of a locking pin assembly under load, specifically addressing whether the pins will shear or deform. Participants explore modeling approaches and calculations necessary to demonstrate the assembly's safety under a total load of 53.5 kN, distributed across four pins.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests modeling the pin as a short beam subject to shear loading, indicating a straightforward approach.
  • Another participant expresses concern about the design of the locking arrangement, suggesting that a more complex analysis may be necessary to ensure safety and functionality.
  • There is a request for clarification on whether the inquiry pertains to professional work or a student project, indicating a potential difference in the expected rigor of analysis.
  • A participant notes the absence of a picture of the pin assembly, which may hinder the ability to provide specific advice.

Areas of Agreement / Disagreement

Participants exhibit differing views on the complexity of the analysis required, with some suggesting a simple model while others indicate that the design issues complicate the situation. The discussion remains unresolved regarding the best approach to take.

Contextual Notes

The discussion lacks specific details about the design of the locking pin assembly and any assumptions that may affect the analysis. The absence of visual aids may limit the depth of the technical discussion.

I currently need to show that the attached locking pin assembly will not shear or deform under load (total load is 53.5kn, shared over four of these pins)

Could anyone advise on how to model this as a beam? Cantilever?

What calculations can I use to prove the pins will not shear or deform to a point where they can not be removed.

Simple answer is that pin is a short beam subject to shear loading .

Difficulty is though that the whole locking arrangement is not very well designed and this means that a much more complicated analysis is needed in order to show that it is safe and that it can can function as required .

Is this professional work or a student project ?

There's no picture of the pin assembly attached to your post. :frown:
 
There was a picture when I answered but now it has gone .
