Im making a vid tonight of some simple mechanical resonance. Will be up in a little while. ;)

Here is a vid of a simple device I made to begin exploring resonance, of the mechanical kind.

I want to find out if there are any advantages to including resonance in mechanical and electronic designs. The mechanical seems like a good place to start, and as we have gone over in other threads, the mechanical functions can be translated into electronic functions.

Ok. gotta git.

One more thing before I shut down and forget.

In the vid showing the magnet causing lenz in the stainless plate and making it vibrate, Im wondering about the reason for lower speed of the drill to get the plate to vibrate. I think I got it....

With the mags on the plate, the mass is more and we should expect a lower freq of resonance than with no mags at all. So, with the mags, the drill is throwing a N then  S in 1 rotation, so push then pull in 1 rotation. But with the lenz(no mags on the plate) the plate cant discern between N and S. So the plate gets 2 cycles per rotation of the drill mag. ;) So the plate is vibrating at a higher freq with the drill going slower.  ::) ;D

Learnin.  ;D Nite

And bingo--there you have exactly what i was saying about adding energy at the right time to get a wine glass to resonate.

Good job Mag's,and this is a great experiment,and just bought in a flood of idea's. ;)

Hey Mag's

Check this out.

Thanks for the idea ;)

How is it we can draw energy from a resonant system,while at the same time,reduce the P/in?.
The video should show all that is required to believe that resonant systems are far more efficient.

I have since made a second system--well same system,but different oscillating arm,where the frequency is higher. It seems that the higher we go in frequency,the more energy we can draw from the system,and the more we reduce the P/in.

I will keep at it for a while,and see how you go with your setup.
It is my guess that you will be able to use less power to run your motor,than it would use running on it's own--they are the results i have gained so far.

Mechanical Resonance !


looks like quite a Bit of fun indeed.

@Mags
I heard mention of Sound resonance in a vid [very low frequency ] ..with a car interior responding in an odd way ??
can you post that ??

thanks

Acoustic resonance is a mechanical resonance, so it can't be TOO far off topic.
You don't want resonance inside your car with a powerful stereo system.
It makes it hard to drive.  (29Khz, and again around 7.9Khz)
Oddly enough, both frequencies are ~resonant with both the cavity of your car and the cavity in your head.

@ Brad
nice test!
I know I posted some 124Hz or something in the video, that was mostly my brain spouting out a senseless number..
When thinking about it,

You should follow a scale, something like:
11.2
22.4
44.8
89.6
179.2
etc.

[Edit: the half-wave below 179.2 would be 134.4 - this may have been where my mind went on YT, (Blurp!)]
   so this was an incorrect place to go, since the 11.2 is ALREADY the half wave...
   I forgot to take into account, the mechanical restriction
  the wave bounces back forming the  "standing wave".
  full wave would include the negative (-) portion.

Nice. ;) that was my next step to use coils.  But I wanted to start off in the simplest form where the drill(after the battery and motor)provided mechanical input and the result was physical output. But Im glad you stopped in and shown that.  Ill be joining you on that. Had to put in a little sound system on a Harley. Weird box for control unit, 4 pretty nice speaker pods. But the brackets sucked. So had to make my own. Still took some refigguring to get them at the right angle and be on there good. Bah, just finished.  He is happy.

But back to topic, I think that as long as there is a mechanical item in the the device that resonates and has every thing to do with accepting the input and we can extract output from it. The mechanical portion must be the main focus of its energy storage capability at resonance compared to not in resonance. Is there an advantage there. ;)   

Thanks for joining in Brad. Im sure this will be a fun ride. ;D Nice vid. Watching it again.

Yep. great vid and good early conclusions.  ;)   Imagine, these are simple setups. We will gradually get to next level stuff.  Its just the resonance thing has just been hitting me lately.  My first experiences with it were fouled up by having too much of the wrong things together to realize any potentials. But since Smoky started talking about it and made it sound like the right thing to go for, Ive felt very uppity and researching things on this that I hadnt seen before. It puts past experiences into perspective.

Again, thanks for making the vid of that Brad. Good show, mate! ;D


And we continue on.....

He has lots of power in this truck. But you will see his dash panels falling out, center console disassembles itself. Ive been in trucks that have more. 5 seconds and you are done for the day back at the hotel in bed. Like sea sickness. Up to 183db.  180db is like standing 100ft away from a space shuttle launch. But at 20 to 25 hz, its a lot of fun. ;D

Been thinking about making a shorter plate and would have to make a strong holder for the magnets because of the back and forth speeds at higher freq. Im sure we will get into it.   ;)


Any help here is very welcome. ;)

Nicely done.

I'm curious what happens when you move the driving electromagnet up or down the length of the resonance rod?

I have switched to a spring steel oscillating strip,and this has raised the frequency to around 33Hz.
I can now draw more energy from the system,and at the same time,the system consume's even less power than the first one that operated at a lower frequency. With this small rise in frequency,the P/in without the oscillating strip in play,is the same as the first test seen in the video.

My first thought was that the oscillating magnet was lowering the impedance of the coil,but in order for that to happen,the PM field amplitude would have to rise before the electromagnetic field produced by the coil--the PMs field leads the electromagnetic field,and this cant happen,as it is the electromagnetic pulses that are acting on the PMs field in order to create oscillation.

This is pretty much the same results i seen with the pulsing coil tests i did,with and without the rotor with PMs embedded in it,that rotated in sync with the pulsing coil.

there is something else going on here,and we need to find out what it is.

Hey brad

Just a curious thing.  When we have say 1 subwoofer and it plays at 100db at 100w, and if we add another sub at 100w we get 106db. Now, it takes a doubling of power to make the single sub get to 103db. So from what I know, we can run 2 subs at 50w each, same total power of the single sub example and we will have 103db. Do you see the advantage???

So, if you happen to have another drive coil just like the one you had shown in the vid and put it on the other side of the mast, then put it in series with the other coil for a push pull config, at the same total power input (will have to make voltage adjustments to get the same total power), you should get more movement of the mast for less input.

Would be interesting to see. ;)   Lol, if you put 25w each to 4 subs, you get 106db.  12.5w to each of 8 subs, 109db.

So now, if it works with 2 coils in series and the pendulum moves more, then I suppose we can count on even more savings from the pendulum movement. ;) ;)

Hope I got that right. Have to go. didnt eat today yet. :'( ;D

 "you should get more movement of the mast for less input."
Here I should have written for the 'same input'.
