Claims (3)

1. Способ определения состояния объекта при вибродиагностике, включающий получение вибродиагностических параметров в виде вибросигнала (перемещение, скорость, ускорение и т.п.) исследуемого объекта во временной области, отличающийся тем, что сигнал не переводится в частотную область, а строится фазовое пространство (пространство состояний) по перемещению и (или) его производным количеством n (n=2, 3, 4,...), по выбранным подпространствам которого можно однозначно определить тип дефекта и его количественную характеристику на фоне других повреждений.1. A method for determining the state of an object during vibrodiagnostics, including obtaining vibrodiagnostic parameters in the form of a vibro-signal (displacement, speed, acceleration, etc.) of the studied object in the time domain, characterized in that the signal is not transferred to the frequency domain, but a phase space is constructed ( state space) by the displacement and (or) its derivative number n (n = 2, 3, 4, ...), from the selected subspaces of which it is possible to uniquely determine the type of defect and its quantitative characteristic against the background of other damage eny. 2. Способ по п.1, отличающийся тем, что на выбранных подпространствах выявляют точки бифуркации, которые устанавливают границы между грубыми и точными системами, таким образом определяют и прогнозируют переход объекта из одного качественного состояния в другое. 2. The method according to claim 1, characterized in that on the selected subspaces bifurcation points are identified that establish boundaries between coarse and precise systems, thus determining and predicting the transition of an object from one qualitative state to another. 3. Способ по пп.1 и 2, отличающийся тем, что по скорости изменения количественных параметров и по скорости прохождения системой точек бифуркации осуществляют прогноз развития дефекта. 3. The method according to claims 1 and 2, characterized in that according to the rate of change of quantitative parameters and the rate of passage of the system of bifurcation points, a forecast of the development of the defect is carried out.
