I expect the spring leg will become slightly curved, and that the wall will be dented slightly.
You will probably need to better define the contact points of the spring and legs with the wall.
I'm making CAE Analysis at Catia and I want to see the wall deformation which happens at set and full stroke positions of springs (under load). To make this analysis I need the enter the force values. But I'm not sure how to calculate it.Lnewqban said:What do you mean by deflection of the walls?
Do you know the RPD (rate per degree) of this spring?
I attached one more pic. I hope I could show it clearly.JBA said:We need to see a side view of the assembly to understand how and where the two walls are supported along their lengths.
Baluncore said:You do show a local point contact for F2 on the green.
F1 will not be spread over the length of the leg as you show.
You need to provide a local point of contact for F1 on the yellow.
If necessary provide a bump of yellow to contact the end of the leg.
You must also consider which (three?) points of contacts hold the coil of the spring in place.
That may be F3 where the coil touches yellow material.

I have the values of springs, I know the Torque values under this positions but how can i find the leg's reaction forces?

A torsion spring reaction force is the force exerted by a torsion spring when it is twisted or rotated. It is the force that opposes the twisting motion and causes the spring to return to its original position.
When a torsion spring is twisted, the coils of the spring are compressed or stretched. This causes the spring to store potential energy, which is released when the twisting force is removed, causing the spring to return to its original shape and exert a reaction force.
The magnitude of a torsion spring reaction force is affected by the material and size of the spring, the amount of twist applied, and the distance between the two ends of the spring. The tighter the coils and the greater the twist, the stronger the reaction force will be.
The formula for calculating the torsion spring reaction force is F = kθ, where F is the reaction force, k is the spring constant (dependent on the material and size of the spring), and θ is the angle of twist in radians. This formula assumes a linear relationship between the force and the angle of twist.
Torsion spring reaction forces are commonly used in a variety of mechanical devices, such as door hinges, mousetraps, and clock springs. They are also used in more specialized applications, such as in torsion pendulum clocks and in the suspension systems of vehicles.
