Abstract: | In this article, we propose methods that increase numerical efficiency of dynamic simulation of spatial multibody systems
described in absolute coordinates. The successive coordinate projection method efficiently stabilizes the system constraints
in the case when a non-minimal set of orientation coordinates is used to describe the orientation of bodies in space. The
new procedure of generation of Newton–Euler equations is shown in detail for systems with the most popular types of joints
(prismatic joint, revolute joint, etc.). The proposed algorithms were tested with models of a governor mechanism and Yamaha
YZF-R1 motorcycle engine. The simulation results show that the successive coordinate projection method is stable and can be
implemented for complex mechanical systems. |
