Abstract: Truck transport plays an important role in the distribution of goods. Although the lab-simulated truck vibration test has been developed, the vibration wave pattern was different in different measurement condition of truck vibration. To obtain the appropriate sampling intervals condition for the consecutive measurement during truck transport, the effects of sampling intervals on truck transport vibration levels were analyzed. The vibration through the transport trip was measured consecutively in the rear platform of 20-ton loaded truck for the peach distribution from Nagano to Tokyo. The vibration data was sampled with different intervals, and was analyzed with power spectrum density (PSD). With a longer sampling interval, gap with consecutive wave patterns become bigger, and the real vibration cannot be reproduced. It was found that intermittent 60 s sample periods with 4 s and 2 s sub-recorded lengths were sufficient for reproduce local roads and highways vibration. The reason for this difference was that shocks occurred more frequently on local roads than highway.
