AutoCAD Inventor :: Curved Rectangular Spring / Animate
Sep 23, 2012
A multi-part question:
1.) How do you recommend I model a rectangular spring?
2.) How do I apply the concept from the initial question and apply a curve to the spring?
3.) How do I mimic the properties of a spring in animation?
I have a unique part that needs to be generated in IV. It is a sping that follows a curved path (see attachment). I do have complete information, just need to draw it in.
I have drawn a rectangular double curved roof (hyperbolic paraboloid). Did that just by adjusting shape handles up and down in diagonally opposite corners.
I want to draw a grid on it mostly as a graphical thing, so its shape is evident. Have tried model lines which won't attach even when grouped.
I want to create a rectangular picture but I want quite pronounced curved corners
I now I can change all the corner pixels to a differant colour ot make them transparent but as I want to do this to lots of pics I am hoping there is an easier way.
I have been practicing my modeling technique and decided to create a faceted round gemstone model. I started with a 16 sided cylinder and manipulated the vertices until I had my model. However, it is supposed to be a round gemstone and not one with 16 flat sides. Everything worked as far as creating all of the facets except in the "girdle" area. This is the area that joins the top and bottom halves together and is the only part that is supposed to be round. What I need to do is to make each of the 16 rectangular polygons curved in the horizontal direction and leave them flat in the vertical direction.
I want to extrude a big number of pillars to a rather complicated surface and that works out fine. But each end of the pillars warps around the surface and I want them just to go up to it and stop with a resulting horizontal face.
How do i get the spring to have a compressed look with flat end....i try different settings but not able to have the spring rings to touch for a compressed look.
I can't make a spring moving according to other parts' behaviour. I use Inventor 12. by the way I sent two photos (scanned by Microsoft Security Essentials-no problem), the spring in the photos was made by design accelerators-as compression spring. I want from spring to move with the other parts but it doesn't. For instance when I pull the blue part down, blue part, and the spring go the into of each other.
Inventor offers us several options to design a coil of constant pitch with a tapering diameter. However, I am unable to create a coil with a taper and a changing pitch at the same time.
We are using Inventor 2013. I would like to produce similar parts as the attached 2D drawings in 3D, only with a changing pitch (distance between revolutions) per revolution. Can it be done? There is software for the CNC spring manufacturing machines to produce such parts. Therefore the proper inputs to produce these effectively and efficiently, are available somewhere.
The part I've been describing uses .09 diameter wire and has about 54 coils in about 8 inches. The starting inside diameter is about .53" and the pitch is about .27" the ending inside diameter is .109" +/- .01 with a pitch of about .091".
Here are 2D drawings of similar parts, the last (NF3) is closest to what we need.
I have a piece of steel that I need to flex. It is a piece of blue tempered spring steel pressed against the corner of a brass pressure transfer. The opposite end of the transfer is tangentlly constrained to a latching mechanism. When the latching mechanism is lifted, the transfer rotates slightly around a screw (made invisible) and the spring is flexed. When the latch is released, the spring returns the latch to the closed position. I have several other assemblies that use the same principal, but some with just a piece of mild steel used as a cover as well as a spring.
Is there a way to create a Coiled spring of 26 coils on an arc radius of 3.781inchs arc length of spring is 13.706inc
The major dia of the spring is 3/8 inch with the wire dia is NOT given
The original Hand done drawing are attached in PDF version 6 format
As for Inventor I'm using 2012. It is the first time I have come across this sort of problem I thought of doing a single coil and creating a sub assemble of it around a construction line arc rad with each coil mated and rotated at an angle to the other but then thought that there must be an easier way of creating this spring.
I use inventor 2011 and i want to create a spring animation. I followed this video step by step but when i constrain the upside and the downside of the spring to those plate objects i get an error.
Can I use the spring generator to design a spring for me? I know my spring rate, my loads and my dimensions. I don't care how many active coils the spring has as long as it performs to the specifications I've calculated.
I'm designing a hinged cover for something right now that will use a pair of gas extension springs for assisted opening. I'm currently working to figure out how much force it will take to open the cover using different values of spring - it's available in 50, 100, 150, 200, etc., lb versions.
I've tried running simulations using a force applied to the moving end of the gas spring, and I've trued running simulations using a spring joint applied between the fixed and and the moving end of the gas spring, and I'm getting dramatically different results between the two. For instance, using a 200 lb force shows me that I need about 25 extra lbs of force applied to the handle of the cover to open it, where when I use that same 200 lbs on a spring joint, I need 50-75 lbs to keep the cover closed, because it will open on its own.
I want to insert a spring in an assembly, and for that i will make a spring with the coil command. if i will squeese it between surfaces, will it resemble a spring? will the bindings come closer (i hope they are called bindings, otherwise tell me how they are called)?
I need a conical spring that can change in pitch as it tapers. Basically the spring starts in a compression style and tapers down to an expasion style. The CNC spring machines are capable to produce it, but am I able to, through Inventor? If not when will we have this feature capability?
Im trying to reproduce the part attached. Its a rectangular aluminum tube. .320 x .180 approx an inch long. I tried lofting 2 sketches but the result does appear like the attached image.
Can an equation be used to calculate equal distances when using the rectangular pattern.Regarding the attached .ipt file i would like to place 25 holes in the X direction with equal gap size between each hole.Also how to calculate the number of holes in the Y direction again with equal distance between each hole.I have not done this before with equations but was thinking that i would need to use the Length x Width in the equation.Do i need to add figures into the Parameters box also?
The attached file with the Hole feature the sketch is not constrained for the purpose of using an equation so i know how far from the start of the part to get equal distances between each hole to the end of the part .
regarding obtaining the dimensions of a simple retangular prism?
In this particular case (file attached) the geometry was imported from Revit, so it's really just imported SAT file. After importing, "Make components" was run to generate individual part files. The resulting part is therefore created using the origin of the parent assembly, so although it's "just a box" - it is spatially displaced and oriented at an unknown angle.
I'm looking for a way to identify the 3 dimensions that define the shape of the prism.
I am using Inventor 2012. I have a horizontal feature that terminates at a vertical plane on one end and an angled plane at the other end. I want to pattern it down but when I use Adjust, the patterned features do not adjust to the angled plane. They just go strait down from the first feature.
Does Adjust only work if the terminator is a solid surface instead of a plane?
