“…Without having data from before the participants became haul truck operators, it is not possible to determine the exact source or cause of this reduced capacity to detect touch. However, prolonged exposure to hand-arm vibration due to operating a haul truck is a likely contributor, as previous research has predicted finger blanching in 10% of exposed drivers after less than two years of operating small four-wheel drive tractors (Goglia et al, 2003). The long-term effects of HAV can take over six years before the presentation of vascular or musculoskeletal symptoms (Bernard et al, 1998; Nyantumbua et al, 2007).…”

“…Operators are exposed to HAV through both the steering column and the gear shift lever which transmit vibration from the engine as well as from the movement of the equipment. Both types of vibration contribute to fatigue and can have detrimental effects on health and job performance (Goglia et al, 2003). The effects of WBV exposure on postural stability have been examined in laboratory studies, and results show inconsistent effects on balance (Cornelius et al, 1994; Mannin and Ekblom, 1984; Santos et al, 2008a).…”

Falls from mobile equipment are reported at surface mine quarry operations each year in considerable numbers. Research shows that a preponderance of falls occur while getting on/off mobile equipment. Contributing factors to the risk of falls include the usage of ladders, exiting onto a slippery surface, and foot or hand slippage. Balance issues may also contribute to fall risks for mobile equipment operators who are exposed to whole-body vibration (WBV). For this reason, the National Institute for Occupational Safety and Health, Office of Mine Safety and Health Research conducted a study at four participating mine sites with seven haul truck operators. The purpose was to ascertain whether WBV and hand-arm vibration (HAV) exposures for quarry haul truck operators were linked to short-term decreases in performance in relation to postural stability, touch sensation threshold, and grip strength that are of crucial importance when getting on/off the trucks. WBV measures of frequency-weighted RMS accelerations (wRMS) and vibration dose value (VDV), when compared to the ISO/ANSI standards, were mostly below levels identified for the Health Guidance Caution Zone (HGCZ), although there were instances where the levels were within and above the specified Exposure Action Value. Comparably, all mean HAV levels, when compared to the ISO/ANSI standards, were below the HGCZ. For the existing conditions and equipment, no significant correlation could be identified between the WBV, HAV, postural stability, touch sensation threshold, and grip strength measures taken during this study.

“…The time histories of acceleration values were obtained from the one-third octave band analysis in the frequency range of up to 100 Hz, which is the frequency range of vibration in MA three-tonne truck steering wheels. While the single axis accelerometer does not differentiate the rotational and translational components of the steering acceleration, 39 based on the findings in Goglia et al 22 and Aziz et al, 23 approximation was made in this study to associate the z-axis acceleration time history as the dominant axis to monitor HAV for this type of vehicle. The values of tangential acceleration on the steering wheel were calculated using the following equations after the signal was digitally filtered by the frequency weighting function w hi .…”

“…Eaton 21 found that for various types of buses driven on city streets with the same speed, the dominant vibration was in the x-axis. Goglia et al 22 found that vibration transmitted to the steering wheel of small four-wheel drive tractors is more dominant in the zaxis for idle and full load operating conditions. In the idle condition, the highest mean value of frequency-weighted acceleration was 3.47 ms −2 for the z-axis, followed by x-and y-axes with 2.14 and 2.00 ms −2 , respectively.…”

This paper aims to describe the development of a statistical analysis method called the integrated kurtosis-based algorithm for a Z-notch filter (I-kaz) Vibro for monitoring hand-arm vibration (HAV) in Malaysian Army (MA) three-tonne truck steering wheels. HAV from the steering wheel was measured using a single axis piezoelectric accelerometer that was connected to a Brüel & Kjaer Type 3649 vibration analyser. The raw acceleration data was integrated to obtain velocity data and reintegrated to obtain displacement data. The data was analysed using I-kaz Vibro to determine the vibration values in relation to varying speeds of the truck and to determine the degree of data scattering for three-axial raw data signals for acceleration, velocity, and displacement in the x-, y-, and z-axes, respectively. Based on the results obtained, HAV experienced by the drivers can be presented using daily vibration exposure A(8), the I-kaz Vibro coefficient (Z −

“…In addition, Servadio & Belfiore (2013b) studied the influence of the mechanical vibration on human health and assessed it with four methods: the health guidance caution zones, the estimated vibration dose value, the fourth power vibration dose value (VDV), and a combination of the methods. Fairley (1995), Buchholz et al (1997), and Goglia et al (2003) studied different forms of vibration and found that they are transmitted to the driver's body via the seat, to the feet via the 2 height and dynamic adjustment of suspension stiffness. Sankar & Afonso (1993) investigated the lateral ride performance of an off-road vehicle with a seat suspension having a dynamic vibration absorber.…”

The vibration of the driver's seat of agricultural tractors was investigated during three alternative tillage operations. Three tractors including a range of specifications were considered, at a range of forward speeds. The interactions between the tractors, implements and speeds were examined using the SPSS program and the GLM-ANOVA method. The results analysis indicated that the tractors played the first major role in vibration development in the lateral axis and was followed by the implements. In contrast, the implements played the first major role in the development of vibration in the horizontal axis and are followed by factor tractors. The statistically significant effect in vertical and horizontal axes shows the factor implements. In addition, the statistically significant effect in the vertical and lateral axes shows again the implements to be the most significant factor. Of the implements, the plough shows the highest vibration and displays statistically significant difference in comparison with the other implements.
