AutoCAD Inventor :: 2011 - FEA Bolt Head Simulation
Feb 18, 2011
I've been working with Inventor 2011 - Pro and have not had any success with utilizing a bolted connection (blind hole) in an FEA stress analysis. I have reviewed and one suggestion involved a using a bolt placed "as custom" instead of "as standard". It appears however that there is a default setting that I currently have which doesn't allow this as a selection.
trying to draw a hex nut in isometric...I've got the ellipse with the inside/outside dimensions but as far as placing the lines and connecting them to make the hexagon perimeter I keep coming up wrong..
I have unchecked resolve file references, etc, and still basically spends 5 minutes looking for files i told it not to look for. Why doesnt it just open the assembly or drawing, without waiting for ever?
I have some problems with Bolt Connection Component Generator. For placement I choose Concentric, i choose all references, but I can't select Diameter. It is stuck to 10mm and i can't change it.
I have an assembly with a FEA simulation result. I can run a report and get the reaction forces and moments at each constraint. I would like to run a new simulation with different constraints and use the reaction results from the first simulation as loads in the second one.
Currently I do this by running a report on the 1st simulation to get a table of the reaction results. I then manually add those forces to the 2nd simulation. This takes time to type and the forces must be edited each time I re-run the 1st simulation.
Is there a way to use parameters to automate this?
I've assembled a bolt and a slide block that is constrained to a base plate and am able to put everything in motion. I have the slide block constrained to slide the distance of the base plate and when I reach the end the bolt continues to rotate when, if this was a real part, should stop. How can I get this bolt to stop once the slide block reaches its ending constraint?
I'm working on a project in wikiHelp under Inventor tutorials, Content Center, Create iMates. When I pull the object up in an assembly I can create an iMate and it will show that I made one. But when i go to the next page (Place Content Manually Using iMates), I can't get the bolt to snap to the iMate inside the object, the bolt just stays in one position the whole time.
1. When placing pumps,bolt-on walkways etc..etc..on to a metal frame at the assembly level do you place the pumps/walkways first and then add the bolt holes to the frame or do you create the bolt holes first in the frame and then place the pump/walkways on to the holes?
Using bolted connection, I want to place a bolt through 3 sheets of metal. The first 2 sheets i want it to automatically place a slightly larger hole (which it does) but I want the 3rd sheet to be threaded so the bolt thread and hole thread are the same size.
When a bolted connection is used, the bolt changes in length as the stackup of hardware increases and decreases. I have noticed that if I do not grab the red arrow to adjust the length, the amount the bolt extends past the nut
seems to be only about 2 threads. What is the formula Inventor uses to determine this extended length?
I'm trying to constrain a length of ACME threaded rod to a nut so that when the rod is spun or threaded it shows it traveling into the nut as it will be grounded. I would like it to work as a driven assembly or if I was to turn or spin the rod by the mouse. I've reseached this for the last 2 days and can not spend any more time on it so time to ask the experts.
I have a ratchet plate idw that I've drawn and dimensioned, but I would like to insert two bolt circles to the two diameter dimensions that appear to be pointing at nothing. The circular pattern is not made up of circles so I haven't been able to use the Centered Pattern command in the centerline section. I'm using Inventor 2013.
In my work i normally use our standard full threaded rods with square nuts. But, since we make the rods and nuts in the factory, they do not follow any international standard.
I wanted to add the threaded rods to the Bolted Connection menu in order to be able to automaticaly add the rod and to let inventor calculate the needed lenght.
I was able to add the rod to content center as an Ipart with all available sizes, but it doesn't appear on the bolted connections menu.
See attached our normal bolted connection, how can I add this to bolted connection so inventor will size it automatically to the needed lenght?
Im using the bolted connection tool and when i chose all of circluar reference and pick out my bolt and nut the tool will only draw one bolt and ignore all the other circular references. It previews all the bolts just fine ut will only place a bolt in one of the circular references.
I'm trying to assemble two parts, each of which has four matching bolt holes.So I do a "mate" between a hole on one and a hole on the other. This works fine, and the parts now behave just like two parts bolted together with one bolt - one can be rotated relative to the other around the bolt hole. So there is one degree of freedom left to be constrained.
But the obvious ways to constrain that one last rotational constraint result in overconstraint. Trying a "mate" between the circles at the ends of the corresponding bolt holes breaks the first constraint, and the non-grounded object "jumps". Trying to auto-mate the two holes results in the holes being constrained as tangent, with the holes not lined up. I've tried constraining the center points of the end circles of the holes. That doesn't work right either.
Doing the second constraint as "tangent-inside" does work. That's a 1 DOF constraint, which makes sense.It took me a while to figure that out. The help files aren't very useful when multiple constraints are involved.
I want to use a certain bolt from Content Center. Unfortunately, the particular size I want to use does not exist in the content center, but it does exist at one of our suppliers. How can I add this size to Content Center?
Or, can I somehow check out this bolt as an iPart, and then I can modify it (add any size I want, or even make it custom) according to my will?I am using Inventor 2013
I want to change the description of a bolt to be "M(bolt size) bolt. then add the length in another column. example M10 bolt.
I want to know if it is possible to do this using the Family Properties & changing the "Family Description" to something like M=<NND> BOLT. i have tried but had no luck as it only comes back with "M Bolt" & no diameter
The problem is simply reconciling stress analysis results with hand calculations and I suspect I'm simply setting up constraints incorrectly or something.
A simple problem of an M6 bolt in single shear as in the image below. I am using the formula in image to calculate the shear stress. The diameter (being an M6 bolt) is 6mm and hence radius is 3mm with a shear force of 1000 N being used. Using the formula in the image below and the figures above, I calculate the shear stress in the bolt to be 35.4 MN/m^2 or 35.4 MPa if you prefer.
My problem is that when I simulate this problem in Inventor 2013 stress analysis the results (for any kind of stress analysis; Von Mises, 1st and 3rd principal, all the planes etc...) are way way off what the hand calculation is, ranging from 160 MPa to around 800 MPa.how to set this example up in Inventor correctly so that you get the same (or near enough) result.
I have a frame member and a plate bolted together using the bolt connection feature. I moved the frame member slightly and while the bolt and nut moved the hole in the plate did not. Do I have to redo the connection when I adjust the position of parts to get the hole to stay in line with the bolt?
At my workplace it has been standard practice in Autocad to call out bolt assemblies in a parts list as: 1/2-13 unc hex hd. bolt w/flat washer & nut. How to do this in Inventor? I know I can enter this info on the assembly iProps for the bolt assembly, I was hoping someone came up with an automated format, maybe pulling info from the bolt itself to populate the assembly iProps?

I have a problem acessing the fatigue calculation panel in the bolt connections´ tool. Whether I press enable or disable I simply can´t acess it. What should I do to access it?
