Abstract
Изобретение относится к спортивной технике и предназначено для определения коэффициента трения льда беговых дорожек спортивных арен. Устройство содержит две платформы, одна из которых неподвижная, прочно удерживается на льду за счет фрикционного покрытия опорной поверхности, шипов и веса грузов. На платформе закреплены самоустанавливающиеся опоры на винтах, на которые устанавливается платформа для легкого перемещения по льду в любом направлении, механизм создающий силовой толкающий импульс, пусковой механизм, держатели ориентирующие платформу на коньках и лазерный дальномер. Механизм, создающий силовой импульс содержит цилиндр, упругий элемент, шток, рычаг с вилкой, создающий усилие на штоке, который сжимает упругий элемент до тех пор, пока на заданном уровне деформации упругого элемента не произойдет его фиксации в пусковом механизме. Подвижная платформа на коньках содержит также самоустанавливающиеся опоры на винтах, на которые она устанавливается для легкого перемещения по льду в любом направлении. В требуемом месте посредством винтов самоустанавливающиеся опоры поднимают и платформа устанавливается на коньки между ориентирующими штангами и вводится в контакт с наконечником на штоке. На платформе установлены грузы, имитирующие вес спортсмена, буферное устройство, воспринимающее силовой импульс от наконечника на штоке при снятии штока с фиксации пусковым рычажком. На платформе закреплена мишень, отражающая лазерный луч дальномера, который беспроводным способом связан с ПК, где посредством программного обеспечения рассчитывается скорость, ускорение и расстояние, пройденное платформой на заданных участках пути, а также коэффициент трения льда. Изобретение позволит повысить точность измерения коэффициента трения льда и снизить при этом трудоёмкость исследований.The invention relates to sports equipment and is intended to determine the coefficient of friction of ice treadmills sports arenas. The device contains two platforms, one of which is fixed, firmly held on ice due to the frictional coating of the bearing surface, spikes and weight of the cargo. The platform has self-aligning supports on the screws on which the platform is installed for easy movement on the ice in any direction, a mechanism that creates a force pushing impulse, a trigger mechanism, holders orienting the platform on skates and a laser range finder. The mechanism that creates a force impulse contains a cylinder, an elastic element, a rod, a lever with a fork, which creates a force on the rod, which compresses the elastic element until at a given level of deformation of the elastic element it is fixed in the starting mechanism. The skating platform also contains self-aligning props on the screws on which it is installed for easy movement on the ice in any direction. In the required place by means of screws, the self-aligning supports are lifted and the platform is mounted on the ridges between the orienting rods and is brought into contact with the tip on the rod. On the platform, weights are installed that imitate the weight of the athlete, a buffer device that perceives a force impulse from the tip on the rod when the rod is removed from the fixation with the starting lever. A target is fixed on the platform, reflecting the laser beam of a range finder, which is wirelessly connected to a PC, where the software calculates the speed, acceleration and distance traveled by the platform on specified paths, as well as the coefficient of ice friction. The invention will improve the accuracy of measuring the coefficient of friction of ice and reduce the complexity of research.
