Hi all
I am asking you today because I have difficulty in dimensioning the diameter of an indexing finger,
Principle:
When the indexing gate is locked, it will drive the door with the help of a cylinder,
I would like to find the mass limit of the door with a Ø 12mm at the tip of the indexing finger,
Concerning the indexing finger, it is made of stainless steel, tempered (no + info from NORELEM)
Thank you in advance for your help and have a good day,

To determine T, it is necessary to see the type of door guide/support. Is the start gradual or violent?
Hardened stainless steel? I didn't know it was possible
Hello
For me, the problem is not so much the mass of the door as the speed.
Mass only intervenes on shear as a function of the two parameters of acceleration and deceleration speed. If the acceleration is instantaneous, the shear force is greater.
Once the initial inertia has been overcome, the translational forces are low
What is speed:
- acceleration in m/s and over what length
- deceleration in m/s and over what length
- is the travel speed constant
Kind regards
Hi all
Thank you for your help @gt22 / @stefbeno / @Zozo_mp
Attached, a video to help you understand,
I think you have to start with a door of 200 kg max + a total distance of 1m
What do you think?
Thank you in advance and have a good day,
