Sotnikov A. The prevention of parameters divergence of oscillatory movement of CC machine crystallizer on the basis of development of tilting mechanism diagnostics techniques

The object is parameters of fluctuating motion of CC machine crystallizer swinging mechanism. The purpose is decrease of rejections of parameters of fluctuating motion of CC machine crystallizer (oscillation amplitude and swinging radius) from 50 % to 10 % of project values due to development of diagnosis methods of swinging mechanism faults. The methods of the research are the methods of theory of mechanisms and machines, automated synthesis of equalizations of motion of the bodies systems, theory of patterns recognition and theory of fitness to control, vibrometry and multidimensional classification of information. An apparatus is the specialized programmatic complexes, portable analyzer of vibration. Theoretical results - dependence of radius of CC machine crystallizer swinging is first set from amplitudes of oscillation of swinging table. The mathematical model of CC machine crystallizer swinging mechanism with gaps in hinge bearings got further development by the automatic synthesis of motion equalizations. The diagnostic model of mechanism of CC machine crystallizer swinging mechanism was improved, diagnostic parameters were determined, the decision rules of recognition were developed and the scopes of distinction of the defective states of hinges bearings of swinging mechanism of on the basis of discriminant functions of parameters of fluctuating motion of CC machine crystallizer were set. Practical results: the methods of diagnostics of swinging mechanism and control of rejection of radius of CC machine crystallizer swinging are improved. Degree of introduction : the results of researches are inculcated in the bureau of technical diagnostics of department of main mechanic of joint-stock company "MMP "Istil (Ukraine)", were sent to LTD "ITC of "Vibrodiagnostician" (Ukraine), to the Donetsk National Technical University, to the Priazovsk State Technical University and to the National Metallurgical Academy of Ukraine. An area of the use is metallurgical and machine-building.
