AutoCAD Inventor :: Where To Add Wind Load On Hydraulic Cylinder Wellhead Stand
Jul 12, 2012
We created a wellhead stand (top and bottom plates has od of 18" and the body has od of 16.75" thk of 0.5") and ran the stress analysis.
Because we have a cylinder attach vertically to the wellhead stand, so we added the gravity and force (40,000 lb) on the top plate.
Our question is about the wind load. We know there has a software call robot structural analysis but that is not an option yet. And we looked up other pages and knew that we can convert the wind load to pressure. Basically the wind load is on the one side of the hydraulic cylinder (around 13feet tall and od of 6") and rod (around 12 feet tall and od of 4"). But where do we add it to the wellhead stand? on the top plate (flat face) ? or the body (cylinder)?
We attached a sample part. the orange parts = hydraulic cylinder. the green part = top plate. the magenta part = body.
I have a cantilevered arm that must rotate from 0 to 90 degrees. I would like to lift this arm with a hydraulic cylinder. How do I (using Dynamic Simulation in Inventor 2010) graph the actual load that the cylinder is under for each degree of rotation of the arm. I can use the spring/damper/jack joint (using negative values, reverse of a jack) and apply a load and graph this but the load is constantly increasing. In the scenario of lifting this arm the load will actually decrease at some point of rotation. I would like to see the true loads throughout its rotation.
I am currently working on a project in school about hydraulic systems, so i would like to learn how to make a functional hydraulic cylinder. I have seen a few examples on youtube, but none of which explain how its done.
I need to design a platform (total load 5 ton) that needs to be pulled up and lowered with one hydraulic cylinder that operates a cable system. The cable needs to go via wheels and other things to get in the corner of the platform. (I hope you can visualize what i mean with this task)
I wonder if there is a way to simulate cables (or ropes) in Inventor. And if so how can i do it.
In inventor 2013 I want to extrude a horizontal circle on surface of a bigger vertical hollow cylinder. but what i did it enters into cylinder, and i only want to extrude it on external surface.
Any good hydraulics fitting library? I have had some success with Parker, but it's still lacking models of lots of their stuff. I've been to the cbliss.com website, which has a lot, but specifically I'm looking for flareless fittings (high pressure hydraulics).
I am drawing hydraulic steel pipes using the 3d sketch command. I enter in the points representing the change of direction of the center line of the pipe as if it had no bend radii.
The points are entered in using absolute X,Y,Z coordinates, choosing one end of the pipe as 0,0,0.
I then join the points using the line command. I then put the bend radii on using the bend command.
I then draw a 2d sketch of the 2 circles representing the id , od of the pipe on a normal plane at the start point 0,0,0
I then sweep the 2D sketch along the path of the 3D sketch. I then place axes at the center of each straight portion of pipe . I then place points the intersection points of consecutive axes to replicate the original setting out points (3D x,y,z coordinates) that I used in the 3D sketch.
Then I create my idw with 3 orthographic views (showing the relevant axes as a symbols in each view, an isometric view and a coordinate table showing the x,y,z coordinates of each labelled change of direction. I then pull the pipe into an assembly and put the fittings on each end.
This is another IDW showing the fittings and a parts list. I have inventor suite 2012, along with tube and pipe. However I have never tried it.I don't know how it works, maybe it would be better to use that?
Another question on the measuring of pipes. If a sample is made and then backdraughting needs to be done how do you measure it.
Method used before I arrived was measuring lengths and angles. Highly inaccurate. Never worked. Pipes never drawn. Ended up being photographed only, which was not good enough to make spare parts for service technicians in the field, they had to go out to measure on site and make up on site.
I introduced measuring the change of direction vertices of the centreline of the pipe as if there was not bend radius.
More accurate, but highly difficult to measure. Use steel rules and squares. Never right the first time. Always have to check putting the pipe on top of a full scale drawing.
Tried to improve method of measurement by printing out a A0 piece of graph paper and using that as the background to lay the pipe on. Better/easier and more accurate again, but still not spot on, have to check and adjust using the pipe on top of a full scale plot.
Short of buying some type of expensive 3D measuring machine, which in our case would not warrant the cost as we do not do this type of drawing 100 per cent of our time, not even 30 per cent, what is the best method of measuring pipes accurately.
I have been able to get pipe styles etc. and create some hoses but they are not exactly behaving like I thought they would. When I create a hose, some of the points are on the entry and exit of hose clamps, and any of these points seem fully constrained when I looked at the sketch color. I have also created points on the route by entering a distance along an axis or by picking a point offset on a surface or another hose and its seems these are causing the problem when the assembly moves. These points seem to stay in the original position they picked. Is there any way to keep them fixed to the point they where picked on the surface of a part, so if the assembly moves everything updates correctly.
I also wondered if there was a way to set the length of a section between 2 points to allow for the movement of an assembly.
I've started working on a project but I'm a little out of practice. I need to create a standalone application, with a window to view the active model. Essentially, it'll be a viewer tool with some other minor functionality for interrogation.
Alternatively, Is there a way for me to add a viewer window to my form? Like an InventorViewWindow Control or something?I've spent the last day or so searching, but nothing really useful has surfaced.
How can i increase the size of the hose beyond 2" max that Pipe&Run allows it to be? I need the hose more for a visual rather then its acual function. I'm guessing i gonna have to change its paremeters right? if so, how do i and what needs changed?
I am trying to use iMates names to place a hydraulic adapter into an assembly. The adapter has two male ends - one end with an insert iMate matching a cylinder iMate and one end with an insert iMate matching the hose fitting. When placing the adapter, the iMate names are ignored and it is mated backwards using inferred iMates.
Also, I get an error because it wants to mate new instances of the part to the unconsumed iMate of the part that was just placed (which I guess would place parts into infinity). I have changed around the iMate names and matching names every way I can think of, but the names still are ignored, and it uses other deferred iMates.
For my first project we had to create a portable wind turbine, so i've designed a turbine (sketch included as an attachment).
I've worked a little bit with inventor in the past but my experience is unfortunately not so great and i stumbled on creating the ' blades' for this turbine. I also included my ipt ant iam files.
- additional info-
one blade makes a total curve of 120 degrees one blade has a width of about 80 mm the length of the tube is 700mm the diameter of the turbine is 300 mm
I am into tracking solar array's. So designing for high winds is paramount. I wonder if Inventor will have a package for analysis of wind loads. It is a different kind of FEA. Call it a 3-D distributed load.
I need to emboss ( cut in ) some grooves into a cylinder, but in such a way, so that they won't get narrower. What do you think would be the best way to do that?
I have made a sheet metal cylinder with a rip. I am trying to create a seam on this rip as is done in [URL] ....... about half way through.
I have tried to go through the same steps, but I can not select the inside of the rip to built hems and flanges on. I also tried to make the cylinder by sketching 350 degrees of the cylinder instead of creating a rip, This had the same problem.
Why I can't select these edges or how I can work around it?
How can I create a rib that touches a plane and the end of a cylinder? Inventor will not do it since the thickness of the rib does not touch the cylinder (see attachment).
I am trying to CAD a model rocket I just made so I can test the aerodynamics of it. I have all of the individual parts made in inventor, but I am having trouble getting the fins on the rocket.
How can I constrain the fins (which have a flat face) to the outside of the cylindrical rocket tube? The photo shows the fin and the face (the narrow and long face) that I am trying to constrain to the tube.
I have a telescoping cylinder that someone else modeled. It has an extended and retracted positional rep. I want to make it free moving so that is will move in and out inside another assembly. I can get it to move freely and stop at it's extents using contact sets. My problem is that when you jump from a retracted position to an extended position the center rod "escapes" from the housing.
I am trying to Drill a series of holes on a cylinder. I cannot find out how to start the sketch on this surface so that i can drill on the rounded part of the cylinder.
I have attached a zip file of the engine assembly and its components, I couldn't attach one component because it's too big so I hope everything will still work without it, I'm hoping to show gas flow starting at the injector, into the cylinder, through the dumbell valve on the piston and out the bottom of the cylinder, if there is any way to do it in autodesk I'm willing to try as I just don't have a good enough grasp of 3dsMax yet.
How to make a Mitered Elbow from a cylinder this is driven by our Manufacture they would like to roll a sheet of metal and have a stitch cut within the rolled sheet so they can then just cut the additional amount of material between the stitches to get two identical mitered elbows from one piece of rolled sheet metal. Please see the attached doc. to see what I'm trying to do.
