Questions below pertain to using Autodesk Inventor 2013:
What factor of safety value the Shaft Generator program uses when you run the calculations?
Does the factor of safety value change when you are not using the inventor user material option?
Lastly, when exactly do you know when to use the density option in the calculation properties or not?
I have written some VB code which updates parameters in a model. I would like the code to update the shaft parameters. The shaft is created using the shaft generator. I can use a parameters to set the lengths, diameters and fillets. But when the parameter updates the length stays the same. If I open the shaft assembly, click 'edit using design accelerator' and then click 'ok' in the window the shaft updates. Is there anyway to do this automatically?, maybe through iLogic or API?

I created several Parts with the Shaft Generator, and from one moment to another it always says that it can't update the part file with the new shaft when I press Ok.
Here is the original error, I'm german, so of cause its in german, but i discribed above what it says:

How I could go about creating a standard locknut thread, with the shaft generator (easy so far) BUT create a proper single rounded end key way? It does the end of the locknut groove with the rad that exits the shaft, but in complete truth (and 15+ years of experience.) I have never seen this done in the real world.

I am going to have a bearing ride along the cut out and cover this to a linear motion but can't seem to grasp how you do this in inventor 2013.
My company recently installed Inventor 2013. In previous versions we used a part with negative density similar to seawater to calculate submerged weight and CoG.
In IV 2013, it seems that the ability to calculate negative mass is not longer available.
This is how it worked in pre 2013 IV, when I could specify a negative density.
What I have is a spool made of steel. This spool is modelled as an iAssembly with four configurations:
-In air, empty
-In air, filled with glycol
-Submerged, empty
-Submerged, filled with Glycol
For this example, I now need three parts:
-Steel Pipe
-Glycol derived from the inside volume the pipe
-Seawater buoyancy derived from the outside volume of the pipe.
Each part has its own density, and the assembly weight and CoG correspond to the assembly configuration (with or without glycol) and environment (in air or submerged).
The seawater buoyancy represents the water displaced by the total spool assembly, regardless of the contents. To achieve correct weight in the submerged state, the buoyancy material has to have a negative density.
I do not want to make any of the mass parameters static, and I also fear that the CoG might not be updated correctly when using that method.
As I no longer can define a negative density, any optional method to achieve this without overriding the mass value.

View 9 Replies View RelatedI have created a shaft and splined one end of it successfully. The shaft is the same diameter at both ends and I need to spline the other end as well but when I try, I get the following error messages, Cannot create iFeature. Not possible to create shaft groove. Splining the first end went without a hitch but Inventor absolutely refuses to spline the opposite end of the shaft. The shaft diameter is correct for the spline I have chosen (same as the major diameter)

I am using the design accelerator to create a shaft with multiple features. Works well. This shaft is 90"+ in length and although I realize we create in full scale, having it display into my drawing in full scale is unnecessary because one diameter is nearly 60" long. As such I would like to shorten it by using a shaft end, but cannot figure how to do it.
Just to be clear, by shaft end (term used in Mechanical) I refer to the squiggly lines that basically fudge the OAL of a component.
I am trying to create a simulation in which a shaft rotates and the a spur gear attached to the other end rotates with it. When I apply torque to shaft, the shaft does rotate but the gear does not. I believe I have done something wrong with the constraints.

I create a engine assembly and used "Drive Constrain" to rotate the crank shaft. The animation shows the crank shaft turns continuously in one direction. However, when I animate the constrain in Inventor Studio, the crank shaft turned in two different directions (see the vide file attached).
May I know why the crank shaft turns different direction?
I am trying to create a stress analysis on a shaft with two blower turbines attached. What feature in Inventor 2012 is the best way to represent centrifical force on the shaft due to the weight of the blowers and the inputs of rpm and torque.
View 3 Replies View RelatedIn the attached report, safety factor is se to calculate from ultimate tensile stress (485 MPa), and it indicates 1.33 with stresses:
Von-Mises: 323 MPa..............SF = 1.5
1st principal: 303 MPa.............SF = 1.6
2nd principal: -181.2 MPa....... SF =2.67
So, how is inventor getting 1.33 ?
EDIT: if I set it to calculate from yield ( 260 MPa) it accurately reports SF = 260/323=0.8

I would like to know what calculation on the length of a folding feature is performed by Inventor when one folds it. Read my example to better understand my question.
I am trying to fold a part of my sheet 90 degrees, I am going to call the folding part sheet B and the rest of the sheet, sheet A. Now, understand that when I fold sheet B 90 degrees, its face will no longer be parallel to sheet A, but the face of its thickness will. Consider this, now: when I fold the sheet B, there will be an inner part of the folding (which will have the faces of both sheet sections 90 degrees from each other) and the outer part (which will have an angle of 270 degrees between them).
I want the distance between the thickness face and the outer face of sheet A to be X in length. Which is the intial length of sheet B for this to happen? Consider using the BendRadius, Thickness, and other Inventor Sheet Metal parameters that will participate in the equation.
The question surged because I wanted such distance to be 5 in a part with a Thickness setting of 0.5 (as well as BendRadius), but because of this folding length calculation, I had to make sheet B 5.631 in length.

This has been an issue for a long time. Mass calculations for parts with holes on curves do not work properly. On many parts the error comes up with "low" selected. By default each time I try to save the file, the error window pops up.
