Abstract
According to engineering requirements, structure of multibody systems would change and lead to obvious modifications in dynamics model obtained by traditional methods. In this paper, an existing method for rigid body systems with changing structures is extended to systems with flexible appendages, which is more common in engineering. Application of the new generalized approach to a typical 4-body system is actualized. Numerical simulation is carried out and results are the same as theoretical analysis, which indicate the availability and applicability of the new approach.
