Force Plate options?
Force Plate options?
(OP)
Hello everyone, my I have a Pasco Force Platform (http://www.pasco.com/prodCatalog/PS/PS-2141_paspor...) that i'm using in my research where I drop an 8kg ball on on the plate from about 1.5m. my problem is that the plate surface caved in from the force. does anyone know/use a force platform that is able to stand the force so the surface doesn't break and is able to record 1kHz at least? any suggestions would be great. thank you.

I noticed that their example was an airfilled ball ... I suspect you're Way overloading it.

3DDave and IRstuff - it's a lot simpler than that, the essence of the test is that I place helmet padding on the force plate, and then I drop the ball on the pads. Using the force VS time graph for the ball hitting the plate without a sample and then the force VS time graph for the ball hitting the plate with sample, I get a force loss % for that pad.
so, now that my research is more of a priority, I need to get a new force plate, preferably one with a stronger surface, and has a sample rate greater than 1000Hz.

The way it's seen is that the force plate if the head, the pad is, well, the helmet, and the ball is the ball. sure, sometimes both the head/helmet are also moving towards the ball, but i'm just trying to see the Force Loss % if the player wearing the pads wasn't moving, and a ball/puck/object hit the head/helmet.

Your experiment does not appear to conform to the accepted standards for testing helmets for projectile impacts.
