Integrated CAE development of precessional drives using autodesk inventor platform

Abstract

The paper presents the modeling and simulation of precessional drives designed in two variants capable of high transmission ratio and torque for one stage compact construction. The constructions were designed in Inventor and also as multi body systems in MotionInventor. The simulations of the drives provide information concerning positions, velocities, accelerations, point trajectories, forces and moments, energies, as well as contact forces at the contact between gear teeth and satellite teeth and other data concerning the system. The bearings of the two drives were modeled as multi body systems in SolidDynamics for defining an approach for studying the noise emission during running through simulation with possibility of extension to the contact between teeth.
