Simulacije kinematike troosne paralelne mašine

Abstract

U radu se razmatra simulacija kinematike mašina sa paralelnom kinematikom, na primeru razvijenog fizičkog modela mašine. Kompletna mašina je izmodelirana u Pro/Engineer okruženju, i na bazi takvog modela su vršene razne simulacije kinematike. Simulacija kretanja ne samo da nam omogućava da efektno vidimo model u pokretu, već služi i za složene kinematičke i dinamičke analize. Mogu se uočiti eventualne kolizije u toku kretanja, kao i ponašanje u singularnim pozicijama. Savremeni trend razvoja i plasmana proizvoda zahteva i novi pristup projektovanju. Taj pristup zahteva od konstruktora da njegov dizajn bude detaljno analiziran i pre same materijalizacije. Ovo se postiže koričćenjem CAD paketa za 3D modeliranje, a zatim analizom modela kroz različite softvere za simulacije.

This paper considers simulation of parallel kinematics machines kinematics on example of developed machine physical model. Complete machine is modeled in Pro/Engineer, and, based on such a model, different kinematics simulations are carried out. Motion simulation provides not only effective visualization of model in motion, but it is also used for complex kinematical and dynamical analyses. Possible collisions during motion, as well as the behavior in singular positions can be noticed. Contemporary product development and placement demands a new design approach as well. This approach demands of design to be detailed analyzed before its materialization. This is achieved by using CAD software for 3D modeling, and by analyzing model, using different simulation software, afterwards.
