Sorry, I thought I provided 99% of the relevant info and was hoping for an answer. Thank you to all who posted. I will just order a motor and try it...that seems to be the easiest way to know how much torque is required.
Here is a guy who built what I want to build. If anyone is...
May I reframe the issue a bit?
Instead of focusing on the "pendulum" aspect of the design, think of it as simply moving 600 pounds along the horizontal plane. Disregard friction as well. Just a basic horizontal movement of 600 lbs. In that case, how much torque would it take to get the...
Yes, a couple of you commented on this timing "issue".
Originally, I tried to design the propulsion of the bed so that it would synchronize with the natural frequency at which the bed would rock. Just like when I push my kids on a swing. I wait until they swing back naturally then I push...
Thanks for the reply.
A rocking bed that hangs from 4 foot arms on each corner. I came to the 1000 lb figure assuming a worse case scenario. The actual weight of 2 people and bed may be more like 600 lbs. I figured a simplistic explanation may help narrow it down to the bare physics...
Hello,
I am working on a home hobby project and I need a motor to move an approx 1000lb weight back and forth - similar motion to a pendulum - at a rate of about once every 4 seconds. The problem is, I don't know how powerful the motor has to be to accomplish this. And since gear motors...
