Can a Spiral or Conical spring oscillate many times?

[Micheal_Leo]

Hello dear members

we know that force exert on spring as a result spring will oscillate many times , i want to know that is there any possibility that spiral spring or conical spring oscillate like 500 times with only one time external force , any one have made this kind of invention in past 200 years


Thank you

I think this can be accomplished quite easily. Here's a reference:
https://faraday.physics.utoronto.ca/IYearLab/Wilberforce Pendulum.pdf
that describes a lab experiment with a Wilberforce Pendulum; i.e., a mass-spring system that oscillates both linearly and torsionally:

Here are the results of one experiment:

After the starting force, I estimate that this graph depicts at least 150 oscillations before the graph cuts-off. So by optimizing the spring's material and design so as to minimize the internal energy dissipation due to the spring flexing, and by running the experiment in vacuum to eliminate air resistance, it should be pretty straightforward to observe 500 or more oscillations.

Thank you very much for reference i will try it and analyze it

i would like to know that which software i can used to analyze the oscillations for spring mechanism with time

Maybe you can tell us why you need such a spring.

If you take energy from the oscillating spring, you will dampen and reduce the oscillation more quickly.

There are materials with a higher Q than spring steel, used to make oscillators. There are ways to use amplifier circuits to maintain the oscillation amplitude, without changing the natural frequency.

My boss idea
used a spring that can oscilate 1000 times in spring assisting motor mechanism with only one time external force apply

An oscillating spring is not a good way to store energy. It would be better to deform the spring, then when required, extract energy as it returns to its natural state.
