Determining the State of a Nonlinear Flexible Multibody System Using an Unscented Kalman Filter
IEEE Access, 2022 This paper describes an estimator incorporating the Unscented Kalman Filter (UKF) technique and multibody system dynamics, to determine the state of the flexible multibody applications. The dynamic equation of the flexible mechanism is formed using a set

CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT Accurate surface‐pressure prediction over broad operating envelopes is critical for supersonic aerodynamic analysis and design. To overcome the bottlenecks of traditional computational fluid dynamics (CFD) in real‐time performance and computational efficiency, data‐driven deep learning methods have emerged. However, existing data‐driven models

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.

Unraveling authoritarian reform decision‐making: A metacognitive–subcognitive model
American Journal of Political Science, EarlyView.Abstract Recent research indicates that state reforms in East and Southeast Asia have been predominantly top‐down and authoritarian‐led. However, this significant observation implicitly relies on important assumptions about authoritarian decision‐making behavior and psychology that remains understudied.

Standing on a common ground: a comparison of static stability approaches for pallet loading
International Transactions in Operational Research, EarlyView.Abstract At the practical level, the static stability constraint is one of the most important constraints in practical pallet loading problems, such as air cargo palletizing. Approaches to modeling static stability, which range from base support and mechanical equilibrium calculations to physical simulation, differ in workflow, focus, and assumptions ...

INTERACTIVE DYNAMIC SIMULATOR FOR MULTIBODY SYSTEMS [PDF]
International Journal of Humanoid Robotics, 2012 We propose an interactive dynamic simulator for humanoid robots using constraint-based methods for computing interaction forces with friction. This simulator is a part of a general framework for prototyping called AMELIF and is a successful integration of physical models.

Wind Energy, Volume 29, Issue 7, July 2026.ABSTRACT Physics‐based design optimization workflows thread the needle between computational cost limitations and simulation complexity, often compromising between modeling detail and the range of operating design conditions. Multipoint aerostructural optimization of wind turbine rotors has so far been confined to low‐fidelity analyses or to high ...

Analysis of servo-constraint problems for underactuated multibody systems [PDF]
Mechanical Sciences, 2013 Underactuated multibody systems have fewer control inputs than degrees of freedom. In trajectory tracking control of such systems an accurate and efficient feedforward control is often necessary.

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

A numerical coupling model for a multibody system with multiple lubricated clearance joints
MATEC Web of Conferences, 2017 In machines and mechanisms, most of the clearance joints are designed to operate with lubricant fluid, which is an effective way of ensuring better performance of the mechanical systems. The differently located lubricated joints interact with each other,
