METHODS AND INSTALLATIONS FOR TESTS FOR MULTICOORDINATE EXTERNAL VIBRATIONAL INFLUENCE
Abstract
The work provided a comprehensive approach to the problem of creating spatial methods of vibrational excitation in regard to the problem of dynamic tests of the spatial structure of objects on vibration reliability for multi-axis external mechanical force. Theoretically proved the scope and effectiveness of bench tests on vibration reliability for two-axis loading. The effectiveness of two or more coordinate vibrational loading in relation to the spatial structure of objects considered by the example of a three-dimensional object with a discrete structure. Improved methods and schematics of systems for testing multi -axis vibration. The influence of one and two-coordinate vibrational loading on the parameters of amplitude-frequency characteristics of a three-dimensional object when the vibration reliability tests. Theoretical research and practical use of the mutually reinforcing effect of the action of components of the external vibration as applied to the vibration reliability of the spatial structure of objects with their multi-axis loading are relevant and have a wide range of applications. Practical significance of the obtained results is evident when solving problems of vibration and vibration resistance durability of objects designed for operation in conditions of multiaxial mechanical loading.Keywords: vibration reliability, three-dimensional test object, the amplitude-frequency characteristic test
method, the setup diagram.
