Basic drop testing software needed

[BretMan]

I'm a novice regarding accelerometers and am making an effort to put together a simple indoor, single axis drop testing apparatus to do some tests. I think I have the hardware parts identified which will be compatible. I still need the data acquisition software to give me the readings of the Gs at impact. I don't think they'll be much higher than 200g. The only software I've found is at least several hundred $ and provides much more than I need now.

Does anyone know of any data acquisition software than can serve my needs? I just need it to provide the Gs at impact - really basic. It can be old or used or ugly but I do need it to be reliable. If it's free that would be BIG help too as the whole expense of this is for an R&D experiment.

I'm running Windows XP Pro (SP3). Thanks!

From the GCDC FAQ: "The analog accelerometer sensors of the X250-2 are over-sampled by 16X so a recorded 512Hz rate is internally sampled at 8192Hz."


Depending on the market segment for this helmet, the applicable regulations (if any) might provide more information on exactly how the impact test must be performed. Such regulatory requirements tend to be highly prescriptive in respect to the exact test methodology used. But there would also be market segments and market areas where there are no regulations.

Those are good points to remember.

I know my assumption isn't strong enough to make a buying decision on, it's merely a consideration for open minded problem solving. It's definitely worth to first ask those who do testing regularly if it has merit. I'm going to try to dig for some specs and answers from govt. safety standards labs and see if they can offer any insight.
