“…Operator reports on the location of WMSDs experienced during the last 12 months, are consistent with the location of WMSD symptoms reported by forestry machine operators in previous studies (Hansson, 1990;Axelsson & Pontén, 1990;Jack & Oliver, 2006;Gerasimov & Sokolov, 2009;Hagen et al, 1998;. However, the studied operators reported higher 12-month WMSD prevalence in the back and lower prevalence in the neck, shoulder, wrist and elbow than that reported by operators in previous studies Jack & Oliver, 2006;Hansson, 1990Axelsson & Pòten, 1990Hagen et al, 1998).…”

“…Such improvements over the years have contributed to fewer accidents and fewer problems owing to vibrations and working with levers and machines are now being used for longer hours (Komatsu Forest, 2011;Jack & Oliver, 2006). However, many machine operators still experience WMSDs (Hansson, 1990;Axelsson & Pontén, 1990;Jack & Oliver, 2006;Gerasimov & Sokolov, 2009;Hagen et al, 1998;Komatsu Forest, 2011).…”

“…Field studies used to discern the health effects associated with WBV exposure for health guidelines are limited to translational WBV exposures, but rotational vibration may have an impact on operator health [9]. Thus, further investigations into the effects of 6-DOF WBV on health are necessary.…”

A multiple resolution cross-correlation (MRXcorr) procedure was created to align 6-degree-of-freedom (DOF) whole-body vibration (WBV) data time histories collected at the operator/set interface (OSI) and chassis of mobile forestry machinery. Three validation tests were conducted to substantiate the use of the MRXcorr. The results of these validation tests indicate that the MRXcorr can accurately determine the phase shift between two identical 6-DOF data time histories, as well as the phase shift between the 6-DOF chassis and simulated 6-DOF OSI data time histories for forestry skidders. The MRXcorr was also found to align actual field 6-DOF WBV data sets collected on the OSI and chassis of three forestry skidders better than a cross-correlation utilizing the entire length of the data time histories with r 2 -values from regression analyses between the two time histories being greater when those time histories were aligned with the MRXcorr 83.6% of the time.

“…To date, WBV data has been collected on locomotives [17,18], garbage [19] and transport trucks [11,20], as well as military [10] forestry [14,[21][22][23] and mining [24] vehicles. However, no 6DOF vibration data has been recorded on mobile machines within the steel making industry.…”

Whole-body vibration (WBV) of mobile machines used in the steel making industry has not previously been quantified in six-degrees-of-freedom (6DOF). The purpose of this paper was to quantify 6DOF vibrations during the daily operating tasks of 5 commonly used mobile machines types used in the steel making and metal smelting industries. Vibration data were recorded from the chassis of five commonly used mobile machines using a MEMSense MAG3 triaxial accelerometer & gyroscope (MEMSense, SD, USA), and analyzed using custom MatlabTM code. Elevated values were observed at the chassis for crest factors, peak running root mean squared accelerations, and vibration total values, resulting in ISO 2631-1 (1997) comfort predictions ranging from Uncomfortable to Extremely Uncomfortable. Vibration dominant frequencies were generally between 1 and 8Hz. A second peak which occurred at approximately 27 Hz was observed for each vehicle in almost all axes. Occurring at a frequency that has the potential to produce negative health effects, this second peak was probably caused by the engine idling or running at low speeds. Field vibration profiles from this study have been used as inputs to a 6DOF robot for use in a corresponding laboratory study designed to optimize seat selection thus allowing the steel making and other similar industries to select operator seats based on industry specific field vibration characteristics.
