9) ±â¾îÁ¾·ùÀÇ °æ¿ì, Dynamics R4 allows to simulate rotor systems with free orientation of spin axes. Analysis in our software is performed for coupled lateral, axial and torsional vibrations. (No separate analysis for lateral and torsional vibrations)
Our GearSet link allows to model cylindrical gears couplings with spur and helical teethes (inner or outer); bevel gears with consideration of moment in contact. Please see updated User Guide [2] and Tutorial Guide [3]. Especially take a look at our How To [5] - ¡°12 Simulation of bevel gear set¡±
