Please tell me about the initial speed when the spring bounds back.
We are working on improving the property of returning to its original shape after being compressed at a high speed (returning to the setting time in a short time). Please let me know if there is any correlation between the strength of the spring and the speed of return.
Dear Ito, thank you for your question!
There is no document stated the initial speed when spring bounds back.
However, for example, it may be possible to derive it from the formula of energy.
k [J] = 1/2 m v ^2
With v equals the spring constant/2, k can be is calculated. Assuming this is a compression coil spring, the mass is the mass of the effective coil part + one-end seat.
What do you think about this method?
Thank you for your answer.
I have one more question, what does it mean to consider “the effective coil part+ one-ended seat” as the mass?
Also, in this case, a small object is attached to the spring, and it bounds back with the small object. Should it be considered here that the mass of the small object is included?
Dear Ito,
For example, you have a cylindrical compression coil spring and one end of the spring is grounded.
Then, the one end that operates when the spring is compressed and released with the effective coil part excluding the ground end becomes a free part, therefore can be considered as the mass.
Even with a small object attached, the spring still has to work to move it, so it would be more realistic to consider that subject as a part of the mass.
Thanks again for your question!
