Guest Editorial
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multibody system (MBS) dynamics is a very open discipline in the sense that different authors propose drastically different approaches. Several steps are required to address the simulation of a multibody system: modeling, ...
A Procedure to Define Customized Musculoskeletal Models for the Analysis of the Crutch-Orthosis-Assisted Gait of Spinal Cord Injured Subjects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Subjects suffering from spinal cord injury with lower extremity impairment generally use a wheelchair to move. However, some of them are capable of walking with the help of orthoses and crutches. Standing up and walking ...
Assessment of Linearization Approaches for Multibody Dynamics Formulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Formulating the dynamics equations of a mechanical system following a multibody dynamics approach often leads to a set of highly nonlinear differential-algebraic equations (DAEs). While this form of the equations of motion ...
Validation of a Real Time Multibody Model for an X by Wire Vehicle Prototype Through Field Testing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This research focuses on the experimental validation of a realtime vehicle multibody (MB) model whose bodies are considered rigid. For this purpose, a vehicle prototype has been built and automated in order to repeat ...
Determination of Holonomic and Nonholonomic Constraint Reactions in an Index 3 Augmented Lagrangian Formulation With Velocity and Acceleration Projections
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Index3 augmented Lagrangian formulations with projections of velocities and accelerations represent an efficient and robust method to carry out the forwarddynamics simulation of multibody systems modeled in dependent ...
Design, Control, and Pilot Study of a Lightweight and Modular Robotic Exoskeleton for Walking Assistance After Spinal Cord Injury
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Walking rehabilitation using exoskeletons is of high importance to maximize independence and improve the general well-being of spinal cord injured subjects. We present the design and control of a lightweight and modular ...
