The research presents the approach consisting of resonant excitation of objects – elements of technological systems, including the machine tool, fixture, cutting tool, and part. Resonant Nano amplitude vibrations of the object under the action of broadband perturbation, which has a spectrum characteristic of “white noise”, are sources of information about the geometric characteristics of objects and indicators of their physical and mechanical properties. The latter is important for the materials of the workpieces. When a constant uniform field of magnetic or thermal nature is applied to an object, the introduction of Nano amplitude vibrations acquires the properties of technological influence, as a result of which the properties of the material from which the object is made may change. Experimental studies of resonant excitation of an object placed in a strong constant, uniform magnetic field on the physical and mechanical properties of materials of objects, particularly on increasing their hardness, are presented. The universality of this approach is shown under the condition of application of neural network models, which allows establishing the relationship between the parameters of the frequency spectra of resonant oscillations of objects and their geometric and physic-mechanical properties. Based on the presented materials, fundamentally new innovative technological processes can be developed, which have the prospect of wide application in the conditions of resource-saving highly automated production of products of various industries. |
