AN OBJECT ORIENTED APPROACH TO MODELLING OF FLEXIBLE MULTIBODY SYSTEM: FOCUS ON JOINT CONSTRAINS

摘要

This paper proposes methodology for modelling of the flexible multibody systems that undergo large displacement. Physical modelling of such complex system is obtained using bond graphs. The emphasis of this paper has been placed on modelling of joint constrains. This is done in object-oriented software environment of BondSim ®, which enables that an overall complex system be built by combining the components taking from software library. The methods used differs from others is that it is based on velocity formulation and direct integration of the resulting equations. Two numerical simulations are performed and assessed results against the results in the literature.
