Mass Properties Identification of a Rigid Body Using Modal Analysis

In performing vibration analysis of the car engine on the engine support, it is necessary to know the mass properties of the engine including mass, position of the center of mass and mass inertia moments. Because the car engine has a relatively complex geometric shape and is composed of different components with different densities, determining its mass properties faces many challenges. There a...

3D rigid body motion correction in k-space

Introduction: Motion correction of fMRI data is a fundamental step to be performed prior to functional analysis: even subvoxel motion dramatically corrupts the BOLD signal, invalidating the assumption that intensity variation in time is primarily caused by neuronal activity. Unlike the most widely used applications such as AFNI and SPM that operate in the image domain, the algorithm presented h...

Analysis of a Rigid Ferromagnetic Body under Applied Magnetic Fields

Singularity Analysis of Rigid-body, Closed-loop, Shape-changing Mechanisms

This paper presents an analysis to create a general singularity condition for a mechanism that contains a deformable closed contour. This kinematic architecture is widely used in rigid-body shape changing mechanisms. The general singularity equation is reduced to a condensed form, which allows geometric relationships to be readily detected. A method for formulating the singularity condition for...

Identifiability Analysis of Planar Rigid-Body Frictional Contact

This paper addresses the identifiability of the inertial parameters and the contact forces associated with an object making and breaking frictional contact with the environment. Our goal is to explore under what conditions, and to what degree, the observation of physical interaction, in the form of motions and/or forces, is indicative of the underlying dynamics that governs it. In this initial ...
