cable wrapped

[Alberto B.]

hello to all, as from title I have to draw a cord wrapped on a tambruo diameter 200mm and 500mm, the cable is 1600 meters long.
I tried with spirals but I don't know how to combine the various diameters, I also tried with surface, but being at first I probably miss some passage... Do you have any advice? thanks in advance

 

[Mito125]

I don't know if it's the best solution, but if you try with a sweep? Could be a solution.

 

[LaboratorioDieci]

I follow with interest. but, without knowing how to do, I think it is important to know the diameter of the cable.

 

[MassiVonWeizen]

if you have already done something attach it so as not to invent anything and correct what you have done.
write in the profile the version of solidworks

I tried with spirals but I don't know how to combine the various diameters

What does that mean? What diameters do you need to join if it is a wrapped cable? without u drawing or a scheme you have to imagine all possible implicit variants in your description

among other things it would be necessary to understand also the purpose of modeling

 

[Alberto B.]

I tried with sweep... but beyond the slowness with which he performs, I make the spiral of the various diameters that will have the cable... But I don't know how to combine the different spirals... I don't know if I explained... the cable is 10mm, while thanks for the interest.

 

[MassiVonWeizen]

You didn't explain at all.
a cable wrapped on the same diameter and having the same step as it does to have more spirals to join. we can not find a solution on things that you have to imagine
I repeat:
attach files that you are modeling and image or sketch of what you want to get

 

[LaboratorioDieci]

But I don't know how to combine the different spirals. . .

evaluating how the object would be in reality, this would not be an ideal geometry, but conditioned by a quantity of stresses. but assuming that it would still be possible to draw the various layers of the winding, I do not understand what you would need the united cable.

 

[MassiVonWeizen]

Are we sure it's a spiral and not a propeller?

 

[Alberto B.]

As soon as I can put an image, probably, as you say, I'm facing the problem by looking at it on the wrong side. . .


Here we go.

 

[MassiVonWeizen]

Which one?

 

[Alberto B.]

theoretically both....in the sense that it wraps several times along the drum, in fact the drum is 500mm and the cable 1600meters.. .

 

[MassiVonWeizen]

in fact the drum is 500mm and the cable 1600meters.. .

to know wire diameter and step... .

Do you need to wrap 1 kilometer and a half wire? I'm not surprised that solid weeps

What do you need to do this type of model?

 

[Alberto B.]

the client asked, among other things every tot meters I have to put a connector, I really know that it will never be like the design but would like to have it in the assembling... if possible, and I'm trying

 

[MassiVonWeizen]

then the thread must wrap itself a first layer to the bottom of the drum and then return back with a second layer wrapping on a diamyster larger than a thickness and so on for 160 meters?

modeling is slow if you use the pitch equal to the diameter. try to use a smaller hair diameter, the edges do not touch and the sweep is faster. the propellers can join them with splines in sketch 3d, after creating them with a corner start that leaves space between the endsExcuse me if I don't put the part, I have 2020...

 

[MassiVonWeizen]

shirokko, if the last round of a winding you do it with a spiral instead of as a propeller so that the beginning of the spiral corresponds at the end of the propeller and the end of the spiral corresponds at the beginning of the next propeller cannot join the bodies? should all be flat combo surfaces.

I didn't try it, but I think they're not tangents. for the purposes of @alberto b. It can be a good idea. What seems more complicated is to measure the total length of the cable...

I'm sorry, can I ask you what? You just want to see him over the wire? can you think of simplifying and roasting only the last layer so you see cute but then do not make all the cable of 1600 meters? ? ?

 

[MassiVonWeizen]

I tried to use the spiral as last stretch and you can make a unique body.
for the length of the cable I think it is enough to measure a winding + the stretch that makes from bridge with the next one, that is spline or spiral, and to get them how many windings you have to do.
assuming a step of 1mm the length of a winding will be about 314816 and consequently to make 1600000mm it will take 5 windings
