Thank you very much, excognito, it looks like it works the way you described! I will play with it a little bit, to see if I can get some realistic results :-).
Hello everybody,
I'm trying to define a spiral spring with a characteristic as flat as possible (meaning a "k" as small as possible), but the "minimize" function of Mathcad don't want to help me... :-)
Please take a look at the attached Matchad 11 file and tell me what I'm doing wrong...
@CoryPad: I just have to specify, in the single part drawing, the max. allowed tightening torque, in order to not destroy (shear) the thread of the collar, given that the plate where the collar belongs to is made from an ordinary material (S420MC), with lower strength than the standard nuts and...
Basically, the conversion could be made like this:
- for volume: 5.3890440e+06 mm^3 means 5389044 mm^3
- for surface area: 3.6075821e+06 mm^2 means 3607582.1 mm^2
- etc.
so for e+06 you multiply the value with 1000000, for e-09 you have to divide the value by 1000000000, etc.
The straight answer...
Thank you very much, desertfox, for your reply, I think your approach is the most suitable for a quick solving of my task. I will go for it.
@CoryPad: this collar belongs to a support plate and it serves as a fixation point (a standard screw will be mounted in it, fixing this plate on a...
Yes, of course I know that Desertfox and RB1957 are senior members of this forum and I respect them both. I also know that the input I have is not much at all... but it's all I've got.
You mean I should consider only the thread shear and make the calculation based on that, not the combined case...
Wow, thanks a lot, Cockroach! Now that's what I call a comprehensive answer! I think I get the direction now, in order to do the calculation (I was afraid it would not be as trivial as I hoped, but now I have the confirmation ;-) ). Of course I will also pay attention to the different unit...
Yes, indeed, there are 2 different things, that's why I said I just need to know how to calculate the max. torque rating. I'm not sure I can use the standard tables for nut tightening torque, because in this case is a collar, so a metall sheet of a known thickness and there is a non-standard...
Hello everybody,
I am trying to calculate the max. allowed tightening torque of a threaded collar with given height and specified material and thread size (it is a metric, M10 thread). I have to put the specification of the max. admissible tightening torque on the single part drawing, so that...
Amazing, jjengel!
A detailed and very clear (for me) explanation!
I've folowed your description and it worked very good!
As a small remark: it seems that using the "Move segment" command will move the segments in a plane parallel to the current viewing plane, true? It would be a logical...
Thank you, jjengel for your answer.
Yes, it would be very nice if you could explain a little bit more in detail the steps, also considering that my cable path is more complicated and I will have to lead it through small gaps between other parts of the assy.
I have to make just a simple representation of the cable, not necessary with the end-parts. It's have to be done just as a proposal for a possible path for the cable. The problem is, I am not even able to create a plane on a face of the part of the assembly where the cable should be connected...
Oh, I forgot to say that I don't have any additional license for pipe or cable design (such as XPressRoute), so I have to find a way to do it with the basic modules (part or sheet metal modules). Could you please try to explain me how to do it in this way? Thanks a lot in advance!
Hello,
I have to design a bowden-cable between 2 parts in an assy and I need to create the path curve as a 3D curve, in the context of the assy. To do this, I need to reference on some geometrical elements (edges, points, etc.) from other parts in assy, but I cannot/don't know how to use...
Hello everybody,
I'm currently looking for a good and free viewer for .stp, .igs, 3dxml files with measurement function, which will not need a lot of computer resources, could somebody recommend me something? I have used Teamcenter Professional, it worked, but it led repeatedly to crashes, than...
Hello,
I would like to calculate the necessary section of the support for my 1.2 meter offset satellite dish and for that I need to know how to calculate the "wind resistance" (wind load) of the dish. If I would be able to calculate this "wind resistance", I would use the available datas for...
I have to make an assembly of two parts: a lower part and a cover (upper) part). The lower part is already available and I have to make the matching upper part (cover) for it. I have started the cover part by making first a plane on the interface surface of the lower part, on wich I have copied...
It works! Thanks again!
Concerning the plane reference removal, would there be another solution for that, a more "direct" one, like the one for the 2d Sketch?
Hello,
if I am in a sketch and I have projected some edges of 3D solids into it (the 3D solids could be from the same part, or from other parts - if I am working in an assemly), or if I'm just creating a plane in my part, based (referenced) on a solid planar surface from another part in assy...
