Subjects of research: inductive angular acceleration sensor. Purpose of work: development and research an inductive angular acceleration sensor with high sensitivity, adjustable range and more extensive functional potentials for automatic speed control system of train traffic. Methods of research: circuit theory of distributed parameters, accuracy, Energy-Information Method of computer-aided design and Parametric Block Diagrams, as well as research experimental methods. The results obtained and their novelty: a new design of inductive angular acceleration sensor with high sensitivity, adjustable range and more extensive functional potentials, it’s mathematical model has been developed, an approximate function’s equation of steel’s specific magnetic resistance of magnetic inductance taking into account of magnetic resistance of ferromagnetic liquid has been developed, as well as nonlinear differential equation solution is given. The Parametrical Block Diagrams for analytical investigation of static and dynamic characteristics and accuracy of sensors have been developed. Practical value: the research results is that developed inductive angular acceleration sensor has high sensitivity, adjustable converting range and more extensive functional potential. The developed mathematical model allows investigating static and dynamic regimes in a primitive state of development of the sensors. Degree of embed and economic affectivity: the result of the research is introduced in industrial process of the locomotive roundhouse “Tinchlik” of regional railway junction “Bukhara”. Annual economic profit is 3.7 million local currency so’m. Field of application: the results of the research can be used in a primitive state of development of sensors and aimed to automatic adjustment of railway transports and other industry.
