TL;DR: In this paper, a new approach to model and analyze flexible spatial multibody systems with clearance of cylindrical joints is presented, where flexible parts are modeled by using absolute nodal coordinate formulation (ANCF)-based elements, while the rigid parts are described by employing the natural coordinate formulation, which can lead to a constant system mass matrix for the derived system equations of motion.

TL;DR: In this paper, a new methodology is proposed for the dynamic analysis of rigid-flexible multibody systems with ElastoHydroDynamic (EHD) lubricated cylindrical joints.

TL;DR: In this article, a novel computational approach for the dynamic analysis of a large scale rigid-flexible multibody system composed of composite laminated plates is proposed, where the rigid parts in the system are described through the Natural Coordinate Formulation (NCF) and the flexible bodies are modeled via the finite elements of ANF, which can lead to a constant mass matrix for the derived system equation of motion.

TL;DR: In this paper, the dynamics and control of a rigid-flexible multibody system with multiple cylindrical clearance joints are studied via the Absolute Coordinate Based (ACB) method that combines the Natural Coordinate Formulation (NCF) describing rigid bodies and the Absolute Nodal Coordinate Formation (ANCF), describing flexible bodies.

TL;DR: In this paper, a new spatial curved slender-beam finite element and a new cylindrical shell finite element are proposed in the frame of gradient-deficient Absolute Nodal Coordinate Formulation (ANCF).
