Sheet metal clamp stress and deformation calculation

Dovydas · Oct 22, 2019

Hello Engineers,

I need some help to calculate deformation and stress acting on the clamp in the picture. I need to choose the right material and thickness to withstand acting forces.

- Load on the bottom two screws 250Kg.
- Bolts top and bottom M12 x 1.75.
- There is a slot mounting hole at the top.

How do i approach this calculation?

Thanks

"How do i approach this calculation?"

First, assemble 31 X more detail in the problem definition.

Loads, what is being clamped, reasonable estimates of range of wing nut torque, LOTS more.

I do not see how an M12 bolt "at the top" can secure the beautifully sculptured clamp.

By inspection the channel connecting the clamp to the disk shaped base sure is a wimpy thang with mighty sharp corners.
