A derivative-free algorithm for nonlinear equations and its applications in multibody dynamics
Journal of Algorithms & Computational Technology, 2018 Local floating coordinate system is used to represent the deployment motion of each rigid and flexible body of multibody system dynamics. Normal substructure modes are employed to describe the flexibility of a flexible body.

Stable Inversion for Flexible Multibody Systems Using the ANCF [PDF]
PAMM, 2021 AbstractFlexible robots are often non‐minimum phase systems. Thus, their inverse model must be computed by stable inversion. Here, a simplification to the stable inversion process is proposed, which enables its application to complex underactuated multibody systems.

MBD analysis of flexible multibody system with mass loss
Nihon Kikai Gakkai ronbunshu, 2016 In this paper, we propose a formulation method for flexible multi-body systems with mass loss. The method derives the equation of motion using the velocity transformation method, in consideration of the shift of center-of-mass.

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications
Advanced Robotics Research, EarlyView.Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

Vibration Attenuation of Cantilever Beam Using Electromagnetic Delayed Feedback
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This study presents a combined analytical and numerical investigation of a single‐input single‐output delayed feedback controller designed to suppress vibrations in a cantilever beam actuated by an electromagnet positioned beneath its free end. An analytical model was developed using the linearized equation of motion for a transversely excited
