Speed of a spring

[Kieranc]

We have an application where a spring is not able to close our worksholders fast enough. Is there a way to work out the speed of an extension spring? If we put a second identical spring working in conjunction with the original, will it work faster?

Is there a ratio between the tension of a spring versus the speed?

I believe you could use conservation of energy to find your velocity. you know your displacement, spring characteristics, and forces. From that you should be able to find your speed. Having said that, yes placing another spring on the system will increase your velocity because there is more energy introduced into the system.

Conservation of energy will work if you know the mass that is connected to the spring. Assume the restraint is removed, then kinetic energy = potential energy.

I agree, but in his case the part connected will be a direct impact of the speed of the spring. In order to get the most accurate answer, he really needs to either know, or estimate the mass.
