This study assessed the impact of acute exposure to whole-body vibration in skin temperature of the lower limbs in healthy subjects. Twelve healthy volunteers (mean age 24.55 years) were randomly assigned to two groups and were exposed to different whole-body vibration protocols (35 Hz and 40 Hz frequency and 5-6 mm amplitude). Skin temperature was measured before and immediately after exposure. Infrared thermography measurements revealed that skin temperature decreased significantly after exposure to vibration. The results were different for both vibration frequencies. Exposure to 35 Hz vibration produced significant decreases in skin temperature in some of the studied regions of interest and exposure to 40 Hz vibration produced significant decreases in skin temperature in all studied regions of interest.

“…According to [16,17,18,19,20], for field surveillance or laboratory testing, researchers often choose to use the Piezoelectric (ICP) accelerometer. Measuring equipment with a portable vibration measuring system with high sensitivity triaxial ICP accelerometer used to investigate the impact of vehicle loading vibration at bridge approaches at a certain distance set at the beginning of the investigation.…”

This research was conducted to gain more knowledge and investigate the ground vibration induced by vehicle at five different bridge approach location in Batu Pahat, Johor. This research also to illustrate and specify the ground vibration value based on identifying the location of an influence class of vehicle, speed of vehicle and zone of vehicle on bridge approach which are passing through to the bridge approach A (BAA) and bridge approach B (BAB). In describing vibration in the ground and in structures, the motion of the particle is utilized. This research describes the concepts of particle displacement, velocity and acceleration that are used to depict how the ground or structure reacts to excitation. This research observed the ground vibration motion, that is commonly described by identifying the peak particle velocity (PPV). Also presented, a description of the measurement technique, procedures and field data collection. From the sight of view of the result of this research, it indicated that the vibration value is more significant by all the variables. As a result, by the comparison of the variables that had been conducted with respect to the value of this vibration, it was found that the zone near the sensor shows a higher PPV value compared to the zone that is far apart from the sensor location and also vehicle class also plays a role which class IV is higher than class III and class II. The research shows potential to provide and improve the knowledge towards the importance of ground vibration from the vehicle loading by specific evaluation.

The information and the data of the bridge approach condition is important because it allows designers to know the response of the soil once loaded with vehicles and respectable suggestion for correct engineering solutions to beat the matter. There are a few clarifications the reason of problem occurred at bridge approach was recently inspected by other researchers previously and one of the issues is a dissimilarity between the height of the bridge and road on the connection. The objective of this research is characterize and create techniques for field investigation to inspect the effect of vibration from vehicle loading at bridge approaches and this case might be referred to as a repetitive cyclic loading. The aim of this research is to investigate critical location of vibration at bridge approach model by the influence and effect from measurement tools. This research concentrated on constructed field model of the unpaved bridge approach model in Research Centre for Soft Soil Malaysia (RECESS), Universiti Tun Hussein Onn Malaysia (UTHM), Johor, Malaysia. A portable measurement equipment system with high sensitivity triaxial ICP accelerometer used to investigate and measure the effect of vibration loading at unpaved bridge approach field model. Piezoelectric (ICP) accelerometer is now preferable for researchers for the field surveillance or laboratory testing. From the analysis, it can be stated here that the vibration value increases as the speed and vibration level produced changes from L1 to L2. In the transverse direction, it is found that P1 values are larger than P2 to P6 values at both sites BAA and BAB. On the longitudinal direction, the farther away the plate compactor is from the bridge model connection, its value decreases and it is found that the D1 area has a higher vibration value compared to D2 to D5. It may be then, concluded that in this research it is similar to the previous research at the actual study site where the vibration value is high in the area 1m to 2m from the bridge connection.
