3 D MODELING OF FOUR-AXLE MACHINE MANEUVERING

One of the ways to increase maneuverability wheeled vehicles National Guard Ukraine is use a four-axle chassis with two turntables, which will allow machine turn smallest radius, move crab, sideways and around its own vertical axis. The creation such associated large amount various experiments tests finished sample. development computer technology technologies has led software applications for (simulation) modeling, research study properties technical objects systems under different conditions. article developed digital model turntables identified features. For powerful package solid modeling Autodesk Inventor was chosen, provides comprehensive flexible set tools 3D design, visualization, instrumentation, analysis calculations. When building general chassis, main features layout parts assemblies this vehicle were taken into account. forced rotation wheels platforms modeled by entering value single parameter or setting using graph. Depending on needs experiment, graphs displacements, speed acceleration. In course visual simulation maneuvering carried out three options: turning in opposite direction; changing direction movement through difficult maneuver; movement. virtual studies showed that control front, rear both promising way vehicles. addition, created prototype allows you determine characteristics future product, carry analysis, upgrade necessary modification, desired trajectory movement, including when passing obstacles.
