摘要

Solving the problem of measuring the parameters of movement of the complicated flexible constructions is suggested. Choosing setting points of inertial sensors and the processing techniques of the measurements is optimized, allowing the evaluation of existing elastic strains. The problem is solved step-by-step. In the beginning of investigation there may not be present a detailed information on construction, properties of substances of details, methods of their machining and joint. In this case it is suggested to use algorithm of account of shapes and angles of the elastic deformation, based on outcomes of full-scale, model or computer experiment. On the basis of this information advisories on installation of sensors on a construction are stated. Algorithms of selection of the information on evolution of separate modes of elastic oscillations in service are offered. Summation of these modes allows evaluating stress-strain curves of construction in real time.As an example outcomes of probes of strains for a complex aerospace construction are given.
