film development

[ispettore]

Bye to all,
I have a problem that keeps me from finding a solution.
on a surface of revolution (a barrel) I have to apply a film of about 1 mm thick with a certain profile that determines on the barrel itself....
but this film is the result of a slab "plate" cut... but it must have the development of the "bread".
Is there a possibility to draw the profile on the surface and then "spin" it to get a profile on the floor? .

Thank you.

Hi.

Unfortunately it is not possible to develop curved surfaces in the 3 directions.

The only way is a fem solutor.. There are various types especially in the body shop and aerospace sector.

you can actually spy on them if you discuss the structure in many straight parts. . .

realizes the part as sheet (with thin thickness) then you can develop it by allowing local deformations) and thus obtain a discreet approximation. another method: I approach the film to the lateral surface of the cone trunk with the tangent generation segment to the barrel in the middle point of the segment.

hoping to have been sufficiently clear, greeting

Excuse me when you say: developing allowing local deformations, what do you mean? a transition pavement?

Bye to all,


in reality none of the solutions listed would get the required result... approximations, deformation areas that are translated with the simple perimeter etc....

the reatà is that a curved surface in 3 directions (toroidal) cannot be smoothed. . .

Instead, it created a toroidal from a flat surface and through the bmx create a reverse iteration to achieve development (only in case it is regular as the barrel).

the sheet module is used to make sheet metal and does it egregiamente.... but nothing more!! you can not apply a k or y factor that is to a deformation area or surface 3d.... needs a finite element solutor.
