Abstract
Изобретение относитс к области испытани материалов и может быть использовано дл определени коэффициента трени при пластически деформирующем прот гивании. Целью изобретени вл етс снижение трудоемкости определени коэффициента трени путем исключени измерени крут щего момента при поступательно-вращательном перемещении образца. Образец 1 ввод т в соприкосновение с контробразцом 2, нагружают осевым усилием, измер емым динамометром 3, с одновременным вращением вокруг оси. При достижении образцом 1 середины контробразца 2 прекращают вращение образца 1, совершают только поступательное перемещение с измерением осевого усили и определ ют коэффициент трени . 1 ил.The invention relates to the field of testing materials and can be used to determine the coefficient of friction during plastically deforming. The aim of the invention is to reduce the laboriousness of determining the coefficient of friction by eliminating the measurement of torque during translational-rotational movement of the sample. Sample 1 is brought into contact with counterpiece 2, loaded with axial force measured by dynamometer 3, with simultaneous rotation around the axis. When the sample 1 reaches the middle of the contra-sample 2, the sample 1 rotation is stopped, only translational movement is made with the axial force measurement, and the coefficient of friction is determined. 1 il.

Изобретение относитс к области испытани материалов, в частности к способам определени коэффициента трени при пластически деформирую- щем прот гивании.The invention relates to the field of testing materials, in particular, to methods for determining the coefficient of friction during plastically deforming pulling.
Целью изобретени вл етс снижение трудоемкости процесса определени коэффициента трени путем исключени операции измерени крут щего момента при поступательно-вращательном перемещении образца в контробразце .The aim of the invention is to reduce the laboriousness of the process of determining the coefficient of friction by eliminating the torque measurement operation during the translational-rotational movement of the sample in the counter sample.
При этом отпадает необходимость динамометра дл измерени крут щего момента, а измер етс только осева сила, действующа на образец.There is no need for a dynamometer to measure the torque, and only the axial force acting on the sample is measured.
На чертеже изображена схема устройства дл реализации способа.The drawing shows a diagram of the device for implementing the method.
g - угол наклона винтовой линии к оси, который определ етс отношением скорости вращательного движени V 8 к скорости поступательного движени Vn образца, т.е.g is the angle of inclination of the helix to the axis, which is determined by the ratio of the speed of rotational movement V 8 to the speed of translational movement Vn of the sample, i.e.
