| Abstract: | Transport vibration levels in trucks were measured as a function of truck speed, road conditions and load level. The trucks consisted of one normally loaded truck and one overloaded truck with leaf‐spring suspensions. Truck speeds were divided into three groups: 0–30 km/h, 31–60 km/h and 61–90 km/h. Traffic roads consisted of highways, arterial roads (ARs), secondary roads (SRs) and tertiary roads (TRs). The results revealed that transport vibration levels increased with truck speed; TRs contributed to the highest transport vibration levels, followed by SRs, ARs and highways. The power spectral density peaks were at 3 or 3.5 Hz. Overloading probably suppressed transport vibration levels especially at low speeds. Copyright © 2015 John Wiley & Sons, Ltd. |
