Kuzmych L. Methods and means of measuring stresses and deformations of complex structures by the instrument system

The following new scientific results have been obtained in the dissertation. For the first time a new technology of construction of devices for measuring mechanical quantities of work with intellectual sensors on the basis of TED is proposed. For the first time, a method of automatic inseparable correction of the systematic component of the error of the remote measurement based on analog interfaces for strain gauges is developed. Theoretical foundations for the development of instrument systems of complex technical structures were further developed, including the mathematical model of the process for the remote measurement of the parameters of the stress - strain state, and a method for measuring deformations and stresses taking into account the structure of the sensor. The mathematical model of the process of remote measurement of the parameters of stress - strain state of complex technical structures has been improved. Analog interface model for remote measurement of strain gauge signals with automatic error correction under the influence of various destabilizing factors, oriented on remote measurement of stress - strain state parameters by means of multiplexer and resistive strain gauge. The method and advanced means of protection of the measuring channel of parameters of the stress - strain state from interferences of the normal kind have been further developed. The mathematical model on the basis of the measuring amplifier with differential current inputs for work is improved.
