Wave design

[Adam13]

Hi all!

Trying to replicate this wave design in Creo (currently using 4.0) but having some issues... Thought the easiest way would be to divide the wave in 4-5 sections and use boundary blend to merge sketches of the waves profile in the sections. (Then thickening the surface to make it a solid.) But the sharpest top of the waves doesn't behave the way I want. I've tried using the "control points" option in the boundary blend tool to control the shape, but I'm far from happy.

Before going down the rabbit hole of adjusting the control points until I get something remotely resembling the wave, I thought I'd seek out some help from better users than me to see if this is the way to go or not. Or if it's even possible to make such a design in Creo.

TLDR: Trying to replicate this (or similar) wave design. What's the easiest way of doing that?

Cheers!

The physical examples in your pictures appear to be using a waveform generation algorithm. You can replicate this in Creo using curves from equation and intersecting them in 3D space. You get constructive & destructive interference between the two wave functions that generate some interesting shapes.

 Take a look at this interactive demonstrator to get some insight into the behavior and visualize interference patterns.

That looks promising! Although I would need some kind of example equation code to get me started since the math is way above my head. I tried finding some online and found this and this but I can't translate it to something that I can use in Creo unfortunately. Also tried downloading the code for the Wolfram demonstration project but the equations were very complex so don't know where too start really.

If I could get my hands om some starting equations which I can manipulate this might work. Otherwise I fear the formulas involved are a bit too complex. My boundary blend sketches idea is a big no-no, or? I feel I would have more creative freedom and control with that solution...

I tried it using blend, very simple method as you can see in model, not really sure how CNC guys will like it but thats not my problem 😄 Problem is that the model wont look exactly like picture as it needs additional work to fix the height differences on strips(like 1 hour to plane/sketch through the middle of each strip and project it and extrude it). But for CNC this should be enough.

Thank you! Have been playing around with the technique, and it seems to get somewhat close the pictures I attached. Would like to have some control over the z-axis curvature, so the tops don't looks too uniform. I'll play around some more with blend/boundary blend and see if I can get even better results. Many thanks for your input! This is the best so far:

Haven't had the time yet to fully test all the ideas/solutions provided here, but I think the one provided by Radovan_DT will be good enough. So I'll mark that as the solution for now. Many thanks to everyone who's helped! Will come back once I've sat down and modelled some more.

You might want to try a variable section sweep.

Below I used curves to define the peaks and valleys and controlled the spline to be horizontal at each.

Interesting! Could you upload your model?
