Pneumatic or electric actuator for tribometer?
Hi!
We (work group) are designing a tribometer to test materials to wear impact (for example to test teeth impact while chewing).
At the university, we have a tribometer that does that but needs an improvement because it doesn't work properly. It is used a linear pneumatic actuator to promote the impact, but the compressed air net is very instable, which means the tribometer needs a compressor individually, and that's not viable.
I'm not sure if a linear electric motor has the speed and force needed for this application, that was achieved with the pneumatic.
The specifications we need to achieve are:
-max. load: 500N (variable in time in a controlled way)
-25 mm stroke
Can you suggest any linear electric actuator, or any other alternative, that fulfils this requirements?
Thank you!
P.s. Sorry about any mistakes, english is not my native language : )
