How do I measure vibration of a moving object?

2017-05-19 16:23:04

I want to measure the vibration of a rollercoaster cart while it is riding down the tracks. Handheld dataloggers with a pin on them won't work. I'd need something I can attach or place inside of the rollercoaster track. I am worried that conventional dataloggers won't be well suited for this. I have found exactly 0 results on Google for "measuring vibration of moving objects"-like queries. I want to measure 3-axis G-force.

Is there anything you could recommend me to use?

And a google search for "vibration datalogger" gave : https://www.crystalinstruments.com/coco-90-dynamic-signal-analyzer-and-data-collector/?gclid=CPz8w9KO_NMCFSEW0wodzs4FHQ

As the first result....

I'm sure there is more than one way to do what you want, but based on what you have posted and my experience measuring vibration in and out of vehicles, this is basically how I would do it:

I used an earlier version of these data recorders from IST to measure the vibration environment inside ship

    I used an earlier version of these data recorders from IST to measure the vibration environment inside shipping containers and truck trailers as they travelled around the world.

    For this application, I would mount 1 inside the cart using the built in sensors, and a second unit mounted near the tracks, using external accelerometers. Triggering both systems to record at the same time would be tricky, but I would set up optical sensors to trigger both or use one optical sensor to trigger a radio module which would in turn trigger both recorders. They won't be perfectly synced, but probably good enough. I'm sure that the folks at IST would be more than happy to help you with getting this set up.

    Another nice thing about IST is that they rent equipment so you don't necessarily have to make a huge
