Dynamic Modeling and Analysis of Rigid-Flexible Coupled Unfolding Mechanisms Under Transient Actuation

Applied Sciences
Transient mechanisms are increasingly applied in fields such as high-speed aircraft, super high-speed trains, and underwater robots. However, in high-speed motion, large inertial forces are inevitably generated, which can easily lead to elastic ...

Dynamics modeling of a semi-submersible autonomous underwater vehicle with a towfish towed by a cable

International Journal of Naval Architecture and Ocean Engineering, 2015
In this paper, we employ a dynamics modeling method for investigating a multi-body dynamics system of semi-submersible autonomous underwater vehicles consisting of a towing vehicle operated near the water surface, a tow cable, and a towfish. The towfish,

Coupled motion analysis of tether with time-varying length and rigid bodies

Nihon Kikai Gakkai ronbunshu, 2017
In this paper, we discuss the motion of a tethered system during winding a tether in microgravity. When the tether is being wound, it comes into strong contact with the feeding section of the system.

A comparison of finite elements for nonlinear beams: the absolute nodal coordinate and geometrically exact formulations [PDF]

Multibody System Dynamics, 2008
Two of the most popular finite element formulations for solving nonlinear beams are the absolute nodal coordinate and the geometrically exact approaches. Both can be applied to problems with very large deformations and strains, but they differ substantially at the continuous and the discrete levels.

Research on the Dynamic Modeling of Rigid–Flexible Composite Spacecraft Under Fixed Constraints Based on the ANCF

Aerospace
Dynamically modeling the flexible characteristics of large-scale jointed composite spacecraft is challenging. In this study, a dynamic modeling method for rigid–flexible composite spacecraft is proposed based on the absolute nodal coordinate formulation (
