MBD analysis of flexible multibody system with mass loss

Dynamic Synthesis of a Flexible Multibody System

Abstract—This work denotes an insight into dynamic synthesis of multibody systems. A set of mechanism parameters design variable are synthetized based on a desired mechanism response, such as, velocity, acceleration and bodies deformations. Moreover, knowing the work space, for a robot, and mechanism response allow defining optimal parameters mechanism handling with the desired target response....

Numerical Analysis of Flexible Multibody Systems

H∞ Robust Controller Design and Experimental Analysis of Active Magnetic Bearings with Flexible Rotor System

H∞ controller for active magnetic bearings (AMBs) with flexible rotor system was designed in this paper. The motion equations of AMBs and flexible rotor system are built based on finite element methods (FEM). Weighting function matrices of H∞ controller for AMBs are studied for both the sensitivity and the complementary sensitivity of H∞ control theory. The simulation shows that the H∞ control ...

Modeling Intermittent Contact for Flexible Multibody Systems

This paper consists of two parts. The first part presents a complementarity based recursive scheme to model intermittent contact for flexible multibody systems. A recursive divide and conquer framework is used to explicitly impose the bilateral constraints in the entire system. The presented approach is an extension of the hybrid scheme for rigid multibody systems to allow for small deformation...

Multibody dynamics of mechanism with secondary system

ii To my mother and grandmother who always support me with constant love and pray, my wife who is the anchor of my life and the memory of my father iii ABSTRACT Recent advances in predictive dynamics allow the user to not only predict physics based human motion simulations but also determine the actuation torques required to achieve those motions. The predictive dynamics approach uses optimizat...
