Nikitina G. Methods and test means with mutually reinforcing action of multi-axis vibration and shock load of machine units

The research subject is dynamical processes in the spatial structure objects in multi-axis vibration and shock kinematical excitation. The dissertation objective is the improvement and further development of the theory of spatial objects vibration reliability engineering under multi-axis vibration and shock loading by creating methods and test tools that implement the terms of mutually reinforcing actions constituting external spatial loading.The research methods are theoretical and analytical mechanics methods, modeling theories methods, vibration reliability and applied mathematics methods, method of systems identification, numerical methods of differential equations solving. The methods and means of vibration reliability testing that implement mutually reinforcing action constituting multi-axis vibration and shock loading on the machine components are developed. The obtained results allow to predict and measure the parameters of vibratory activity engineering facilities during design, construction, diagnosis and repairs of machines. Scientific novelty is consists in features of manifestation of mutually reinforcing actions constituting multi-axis vibration and shock loads on the object researching, and on the developing of new methods of machine parts testing. The results of the researches are used on State Enterprise Kharkiv Machine Building Design Bureau named by A.A. Morozov and Utility Company "Kharkiv Car Repair Plant". Application branch - is mechanical engineering , transport.
