The paper aims to identify the influence of deicing chemical contaminating automobile headlamps on light intensity in wintertime. Methods. Researches on the influence of deicing chemical contaminating automobile headlamps on light intensity were analyzed. Experiments on automobile lights contamination in wintertime were conducted under real road conditions. Variation in lights intensity due to contamination by deicing chemicals was studied. Results and discussion. Experimental methods for studying the influence of contaminated automobile headlamp beam transmission during the continuous automobile operation on the headlamp intensity were developed and approved. The experimental results are presented in tables, diagrams and graphs. Conclusions. The authors found that on winter roads covered with deicing chemicals, external automobile lights, including headlamps are contaminated. New data on the influence of headlamp contamination by deicing chemicals on light intensity at night were obtained. The experimental results were verified by curves which can be used for studying the influence of automobile headlamp contamination on light intensity in wintertime.
АННОТАЦИЯ Вв едение. Автомобильный транспорт был и остается самым опасным видом транспорта современности. За один год на дорогах нашей страны гибнет около 25 тысяч человек, получа-ют ранения и увечья более 250 тысяч. Каждое третье дорожно-транспортное происшествие
The article aims to identify the influence of headlight contamination on the stopping distance and allowable speed on roads covered with chemical anti-icing materials at night. Headlight contamination effects were analyzed for determining the maximum allowable vehicle speed on winter roads covered with chemical anti-icing materials in dark conditions. The maximum allowable speed and stopping distance of the vehicle with contaminated headlights were calculated accounting for road visibility in dark conditions. New data on the influence of car headlight contamination, length of its stopping distance and maximum allowable speed on roads covered with chemical anti-icing materials were obtained.
Устойчивость движения автотранспортных средств в холодное время года обеспечивается способностью автомобильных шин к созданию боковых реакций на зимних дорогах. Боковое сцепление шины с опорной поверхностью оценивается ее характеристиками бокового увода, по которым определяют коэффициент бокового сцепления и критический угол увода шины. С применением химических противогололедных материалов существенно ухудшились сцепные свойства шин, особенно, в боковом направлении. Отсутствие знаний о процессах движения шины с боковым уводом на зимней дороге, покрытой химическими противогололедными материалами определяет актуальность научного исследования. В статье рассматриваются нестационарные характеристики бокового увода легковых фрикционных шин Amtel NordMaster175/70R13, полученные по результатам их испытаний на зимней дороге общего пользования, покрытой укатанным снегом и песчано-соляной смесью. Графики показывают, что применение хлорида натрия снижает боковое сцепление фрикционных шин и устойчивость движения автотранспортных средств. Цель – получение нестационарных характеристик бокового увода легковых фрикционных шин на дороге, покрытой укатанным снегом и песчано-соляной смесью, и оценочных параметров бокового сцепления. Метод или методология проведения работы: дорожный метод испытаний с использованием разработанных автором методики и шинного тестера для исследования нестационарного бокового увода автомобильных шин. Результаты: получены нестационарные характеристики бокового увода легковых фрикционных шин Amtel NordMaster 175/70R13, определены коэффициенты бокового сцепления и критические углы увода. Область применения результатов: полученные результаты необходимы для корректировки математической модели, позволяющей выполнять аналитическое исследование процессов бокового увода автомобильных шин на дорогах, имеющих зимнюю скользкость.
The paper presents the results of the study of the influence of chemical anti-icing materials on the capability of tires to create cornering forces that affect road holding and steerability of a vehicle. In this article bench and road methods of testing of tires rolling along the planes covered with chemical anti-icing materials have been applied. It demonstrates a research method used to determine the stationary and non-stationary characteristics of the elastic tires pull rolling along the planes covered with chemical anti-icing materials. The experiments are obtained in bench conditions on a special tire tester developed by scientists of the Department “Road transport” of Irkutsk National Research Technical University, as well as in road condition on a tire tester developed by scientists of the Department “Road transport” of Irkutsk National Research Technical University and the Department “Automobiles” of East Siberia State University of Technology and Management. The experimental results are presented in graphs. Obtained results allow concluding that on the roads covered with chemical anti-icing materials (CAIM) the capability of tires to create cornering forces is sharply reduced.
