高速履带式车辆覆雪路面的机动性能分析与试验研究
Mobility performance analysis and experimental study of high-speed tracked vehicle on snow-covered road surface
摘要
Abstract
In order to study the influence of snow-covered road on the maneuverability of high-speed tracked vehicles in extremely cold regions,based on the relevant standards of tracked vehicles,through theoretical analysis and real vehicle tests,it was found that snow density and thickness were the key factors to determine the maneuverability of snow-covered road.The results showed that,compared with the compacted snow(with a density of 600～750 kg/m3),loose snow(with a density of 120～250 kg/m3)could provide greater adhesion and driving resistance for vehicles,and had a relatively low impact on vehicle′smaneuverability.When the snow thickness on the snow covered road surface was 10～30 cm,the maximum speed of the vehicle was reduced by about 26%compared with that in normal temperature regions,and the ability to pass through longitudinal slopes decreased by more than 50%.When the vehicle was driving in a straight line,the characteristics of the snow had little impact on its maneuverability,but the ability to pass through longitudinal slopes decreased significantly.The research conclusions indicated that the snow on the road surface would reduce the vehicle′s adhesion ability and braking ability,thus affecting its maneuverability and driving safety.关键词
