Mechanic Waveguide and Problems of Breakage Detection, Damage Identification Under Extreme Loading

摘要

Results of theoretical analysis and experiments in non-traditional approach of dynamic processes simulation for determination of characteristics of expert system measuring channel is presented by this paper. Methodical aspects of "vibro-wavelet" processes generation and principle of mechanical waveguide (MW) loading is considered. Structural scheme of dynamic processes generator is offered. The generator of impulsive waves and chaotic processes is itself a mechanic subsystem, in which a loading of MW of no-round cross-section is realized by means of intermediate element - loading law "projectile". Here is a low speed of deformation transforms to comparatively high strain rate. Mechanic waveguide has also a function of formation of quickly proceeding processes with altering parameters (not as a result of dispersion only). Aforementioned processes might cause and cause a damage. Here are shown preferences of such approach in part of application to problems of processes of generation (a "calibration" of measurement channel), for measurements of dynamics of processes of damage, for recognition of "writing" of damage, for information processing, for damage detection under extreme loading/unloading, for damage identification. The modeling and analysis such processes are important for understanding and improving of manufacturing methods too. Concrete examples are shown.
