I am trying to build a Dynamic Scratch Testing rig, however I am unsure what components would best suit my needs. Looking through the NI catalogue they offer a range of products that may fit my application but with limited knowledge on them I was hoping some of you could point me in the right direction.
I'm looking for a linear servo that I can control with a load cell to apply a dynamic force from a vertical position onto a test specimen which will be moving in a horizontal axis.
The load cell and vertical servo will be operating in a range of 0-100N with a travel distance of around 50mm, and the horizontal servo will travel a maximum distance of 25mm at a set speed
I need to be able to control a set rate of force applied in relation to the horizontal speed. e.g. Applying a force from 1-20N over a 10mm horizontal distance over 60 seconds.
Could anyone suggest the type of Load Cell, Servos and Controller I would be looking for to complete this task?
