Examination and assessment of special purpose vehicle crews’ comfort while operating in off-road conditions

In the era of the rapid development of motorization one of the most important characteristics of transport vehicles is the safety and comfort of their drivers and passengers. In particular, people driving vehicles professionally are exposed to vibrations, which may adversely affect their bodies, causing discomfort, dysfunctions, and even lesions of disease. The vibration level triggered by the system a road – a vehicle depends on the type and profile of the road surface as well as the driving speed. Vibration levels are assessed by means of characteristics and comfort comparative indexes determined by experimental methods. Attempts at assessing the comfort while driving along paved roads may be found in many publications; however, there is a lack of information on testing vehicles moving in off-road conditions, which is substantial from the point of view of military vehicle crews’ comfort. The driving comfort of crews of wheeled vehicles is subjected to examinations at the Military Institute of Armored and Automotive Technology.
