In general, I have found that test profiles for shock and vibration should be verified empirically in the end-use application. But if the resources to mount transducers and recording devices in the transported equipment are not available, there are some decent references published by the SAE and FedEx.
It has been my (anecdotal) experience that most of the energy from shipping motion is below 30Hz, but I have seen more than one data run where impulses in the 10s of kHz were recorded. luck, Brian -----Original Message----- From: Paolo Peruzzi [ mailto:[email protected]] Sent: Tuesday, March 09, 2004 1:23 AM To: [email protected] Subject: vibration test Dear all, I'm planning a vibration test in order to simulate a transportation af a trolley at a typical walking speed (1-6 km/h) over a road surface (I suppose an internal building floor is a less critical environment). Could anyone tell me where I can find a rationale to set the test parameters (acceleration amplitude and frequency spectrum, test duration)? I have the MIL STD 810 F curves for reference, but they seem to be not very appropriate for this particular application. thanks, Paolo
