Port-Hamiltonian flexible multibody dynamics [PDF]
Multibody System Dynamics, 2020 A new formulation for the modular construction of flexible multibody systems is presented. By rearranging the equations for a flexible floating body and introducing the appropriate canonical momenta, the model is recast into a coupled system of ordinary and partial differential equations in port-Hamiltonian (pH) form. This approach relies on a floating

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

A framework for establishing constraint Jacobian matrices of planar rigid-flexible-multibody systems
AIMS Mathematics, 2023 Constraint violation correction is an important research topic in solving multibody system dynamics. For a multibody system dynamics method which derives acceleration equations in a recursive manner and avoids overall dynamics equations, a fast and ...

Flexible joints in structural and multibody dynamics [PDF]
Mechanical Sciences, 2013 Flexible joints, sometimes called bushing elements or force elements, are found in all structural and multibody dynamics codes. In their simplest form, flexible joints simply consist of sets of three linear and three torsional springs placed between two ...
