Simulacija kinematike troosne paralelne mašine sa translatorno pokretnim aktuatorima duž X ose

Abstract

U radu se razmatra simulacija kinematike jedne troosne paralelne mašine. Poznato je da su oblik i veličina radnog prostora slabost većine mašina sa paralelnom kinematikom (MPK). U radu se razmatra razvijeni paralelni mehanizam koji ima povoljniji oblik radnog prostora u poređenju sa sličnim paralelnim mehanizmima. Opisana je struktura paralelnog mehanizma i postavljen kinematički model za sprovedene simulacije kinematike jedne troosne paralelne mašine. Savremeni trend razvoja novih mašina alatki zahteva i novi pristup projektovanju, koji zahteva od konstruktora da njegov dizajn bude detaljno analiziran i pre same materijalizacije, što podrazumeva detaljne simulacije rada mašine u početnoj fazi konfigurisanja.

This paper presents simulation of kinematics of a three axes parallel kinematics machine. As it is well known, the shape and the size of work area are the weaknesses of the most of the parallel kinematics machine tools (PKM). This paper considers developed parallel kinematics mechanism, which has better shape of work area than similar parallel mechanisms. For one three axes machine tool, the structure of parallel mechanism is described and kinematical model for different analysis and kinematics simulations is given. New trends in development of new machine tools demand a new approach to machine design, which requires from designer that his design is analyzed in detail before it is materialized, which means that the work of machine is simulated in detail in the start phase of new machine design.
