Darbe nagrinėjamas juostinio konvejerio skaldos transportavimui projektavimas naudojant šiuolaikinę kompiuterinio projektavimo įrangą. Suprojektuotas ir sumodeliuotas SolidWorks kompiuterinio projektavimo sistemoje juostinis konvejeris skaldos transportavimui. Atliktas konvejerio laikančiųjų konstrukcijų stiprumo tyrimas, nustatyta, kad jų stiprumas pakankamas. Konvejerio pavara suprojektuota ir jos komponentų stiprumo tyrimai atlikti APM WinMashine programinio paketo pagalba. Pagrindinio konvejerio pavaros veleno stiprumo tyrimas parodė, kad jis yra tinkamas dirbti maksimalaus apkrovimo sąlygomis. Atlikti darbai parodė, kad naudojant kompiuterizuoto projektavimo sistemą SolidWorks, projektuose sumažėja klaidų skaičius, bei padidėja projektų atlikimo sparta. / The development of belt conveyor for transportation of macadam, using modern computer aided design (CAD), is analysed in the work. The conveyor was developed and modeled using CAD software SolidWorks. The analysis of the strength of conveyor frame was performed, it was rated that the strength of the frame is sufficient. The drive of the conveyor was developed and the analysis of the strength of its components was performed using APM WinMashine software. The analysis of the main conveyor shaft showed that it is suitable for operation under the conditions of maximum load. The performed works showed that using CAD system SolidWorks, number of design errors and design time decreases.

Linear induction motors are applied in equipments with different requirements set up to the controlled motion parameters. Investigation of motoring and breaking modes remains the relevant problem nowadays. The scientific novelty is based on analysis of non-symmetrical operation modes of linear induction motor at supplying it by a voltage source, developing a generalized model of motoring and breaking dynamic modes and analyzing influence of linear motor windings connection way and control parameters on dynamic breaking characteristics. The coordinate transformations of linear induction motors dynamic models, based on rotational motor with assumptions valid for low speed motor and multi-pole motor, are considered. Mathematical and computer models to investigate symmetrical dynamic modes of linear induction drives are presented. Generalized model to investigate non-symmetrical dynamics modes is elaborated. The results of simulation are presented by dependences on the main variables in the time domain, and dependences on both constructional and control parameters that give possibility to optimize constructional parameters of motors.
