Linear dynamics of flexible multibody systems [PDF]

Multibody System Dynamics, 2016
A new methodology to derive the linear model of flexible multibody system dynamics is presented in this paper. This approach is based on the twoport model of each body allowing the model of the whole system to be built just connecting the inputs/outputs of each body model.

Recursive Dynamic Algorithm of Open‐Chain Multibody System [PDF]

Mathematical Problems in Engineering, 2014
Open‐chain multibody systems have been extensively studied because of their widespread application. Based on the structural characteristics of such a system, the relationship between its hinged bodies was transformed into recursive constraint relationships among the position, velocity, and acceleration of the bodies.

Closed Form Constraint Equations Used to Express Frictionless Slip of Multibody Systems Attached to Finite Elements—Application to a Contact between a Double Pendulum and a Beam

Applied Sciences, 2023
This paper focuses on the numerical modeling of the dynamics of mechanical systems. Robots that can inspect high-voltage lines inspired this research. Their control systems must anticipate potential grab positions appropriately.

Inverse dynamics of underactuated multibody systems [PDF]

PAMM, 2009
AbstractThe present work deals with controlled mechanical systems subject to holonomic constraints. In particular, we focus on underactuated systems, defined as systems in which the number of degrees of freedom exceeds the number of inputs. The governing equations of motion can be written in the form of differential‐algebraic equations (DAEs) with a ...
