“…Additionally, transport vibration is related to various factors including speed and driving performance, road conditions (e.g. roughness, undulation and road curvature), load conditions and truck suspension systems . To the best of our knowledge, little is known on the effects of truck speed, road conditions and load capacities on the transport vibration levels in China.…”

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.

“…With respect to the geometry of the deployment, the north‐south oriented road provides a large number of stationary source points. Lak, Degrande and Lombaert () analysed the frequency response of roads to traffic by taking into account the construction of the road, the type of vehicle and the soil structure. They focused on the near‐field effect (2–64 m) and concluded that the resulting spectrum mainly depends on the eigenfrequencies of the vehicles that range from 2–15 Hz.…”

A B S T R A C TIn regions where active source seismic exploration is constrained by limitations of energy penetration and recovery, cost and logistical concerns, or regulatory restrictions, analysis of natural source seismic data may provide an alternative. In this study, we investigate the feasibility of using locally-generated seismic noise in the 2-6 Hz band to obtain a subsurface model via interferometric analysis. We apply this technique to three-component data recorded during the La Barge Passive Seismic Experiment, a local deployment in south-western Wyoming that recorded continuous seismic data between November 2008 and June 2009. We find traffic noise from a nearby state road to be the dominant source of surface waves recorded on the array and observe surface wave arrivals associated with this source up to distances of 5 kms. The orientation of the road with respect to the deployment ensures a large number of stationary points, leading to clear observations on both in-line and cross-line virtual source-receiver pairs. This results in a large number of usable interferograms, which in turn enables the application of standard active source processing methods like signal processing, common offset stacking and traveltime inversion. We investigate the dependency of the interferograms on the amount of data, on a range of processing parameters and on the choice of the interferometry algorithm. The obtained interferograms exhibit a high signal-to-noise ratio on all three components. Rotation of the horizontal components to the radial/transverse direction facilitates the separation of Rayleigh and Love waves. Though the narrow frequency spectrum of the surface waves prevents the inversion for depth-dependent shear-wave velocities, we are able to map the arrival times of the surface waves to laterally varying group and phase velocities for both Rayleigh and Love waves. Our results correlate well with the known geological structure. We outline a scheme for obtaining localized surface wave velocities from local noise sources and show how the processing of passive data benefits from a combination with well-established exploration seismology methods. We highlight the differences with interferometry applied to crustal scale data and conclude with recommendations for similar deployments.

“…They use to primarily consider aspects related to the track conditions (as the used of paved [16,17] or unpaved roads [18]). Firstly, measures reveal that the amplitude of vibration does not represent the only aspects to be considered for evaluating the damage effect on packages, but also the frequency is noteworthy.…”

Handling and transport can turn out to be a disastrous experience for the integrity of goods and products. This fact has encouraged the attention of producers towards the development of measures aiming at maximizing this integrity. At the same time, to obtain really effective solutions, the environmental conditions and the level of stress acting on these products during their way from the producer to the final customer have to be detected. This paper illustrates some between the most relevant methods and experiences for monitoring palletized products.
