The purpose of the work: development of advanced techniques of kinematic and energy calculations of engineering structures on the basis of creation of new mathematical models and widespread use of information technology. Research methods and equipment: theoretical analysis, mathematical modeling, packages of applied computer programs, modern computing equipment. Results: based on Lagrange-Maxwell analogies mathematical models of a number of electromechanical systems are created - pendulum in a fast-changing magnetic field, Ueda oscillator, Duboshinsky pendulum, ferroresonant LRC - circuit with current-dependent inductance, dynamic systems with variable inductance and T. Rikitaki dynamo-machines. The nonlinear dynamics of these devices have been studied using the created models. An additional calculation unit has been developed for the end-to-end computer programs of simplified calculation for strength of statically determined two-support and cantilever I-beams created in the first stage of operation. The developed block allows to determine linear and angular displacements at given points of beams by the Mora method and to build graphs of these displacements. Comparative data on the accuracy of these computerized and traditional ("manual") calculations are given. A three-dimensional mathematical model of motion of a spherical pendulum on a nonlinear elastic suspension under the action of variable aerodynamic lateral influence is created. A computer program for implementation of the created model is developed and illustrated. A 4 DOF dynamic model of extra heavy cargo transportation by a bridge crane with a traverse and bifilar fastening is developed. Product Description popup.authors popup.nrat_date 2020-10-01 Close
