Изобретение относитс к машиностроению и может быть использовано при неразрушающем контроле процесса трени в узлах машин.The invention relates to mechanical engineering and can be used in the non-destructive control of the friction process in machine components.
Известен способ исследовани трени заключающийс в том, что в процессе испытани на трение регистрируют контролируемый параметр, например, суммарную интенсивность эмиссии волн напр жений , и врем , за которое этот параметр достигает посто нной величины. Стабилизаци контролируемого параметра позвол ет оценить момент окончани переработки или установить бид .трени 1A known method for studying friction is that during a friction test, a controlled parameter is recorded, for example, the total intensity of stress wave emission, and the time it takes for this parameter to reach a constant value. The stabilization of the monitored parameter makes it possible to estimate the moment of the end of the processing or to establish a bid.
Однако данный способ имеет низкую точность оценки времени перехода от одного вида трени к другому обусловленную тем, что скорость нарастани эмиссии волн напр жений не соответствует видам трени , которые могут реализоватьс при испытани х.However, this method has low accuracy in estimating the time of transition from one type of friction to another, due to the fact that the rate of increase in the emission of stress waves does not correspond to the types of friction that can occur during testing.
Цель изобретени - повышение точности оценки времени перехода от одногг / вида трени к другому.The purpose of the invention is to improve the accuracy of estimating the time of transition from one type of training to another.
Поставленна цель достигаетс тем, что согласно способу исследовани трени , включающему регистрацию в процессе испытани на трение контролируемого параметра и времени, в течение которого этот параметр достигает посто нной величины, по которому суд т о виде трени , за контролируемый параметр принимают активность акустической эмиссии .This goal is achieved by the fact that according to the method of researching friction, including registration during the friction test, a controlled parameter and the time during which this parameter reaches a constant value, according to which friction is judged, acoustic emission activity is taken as a controlled parameter.
