Transient conformal TEHL algorithms for multibody simulation [PDF]

Modeling, Identification and Control, 2018
This article describes aspects of transient thermal elasto-hydrodynamical lubrication (TEHL) contact modelling for conformal contacts. This is to be utilized in a multibody simulation (MBS) framework for engineering purposes.

On validation of multibody musculoskeletal models [PDF]

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2012
We review the opportunities to validate multibody musculoskeletal models in view of the current transition of musculoskeletal modelling from a research topic to a practical simulation tool in product design, healthcare and other important applications. This transition creates a new need for justification that the models are adequate representations of ...

Design, Modeling, and Vibration Control of a Damper Based on Magnetorheological Fluid and Elastomer

Actuators
The aim of this study is to propose a damper based on magnetorheological (MR) fluid and elastomer for application in vehicle engine mounting systems to dissipate the vibration energy transferred from the engine to the vehicle body.

ED-FNN: A New Deep Learning Algorithm to Detect Percentage of the Gait Cycle for Powered Prostheses

Sensors, 2018
Throughout the last decade, a whole new generation of powered transtibial prostheses and exoskeletons has been developed. However, these technologies are limited by a gait phase detection which controls the wearable device as a function of the activities

Analyzing and Optimizing Multibody Systems [PDF]

Mechanics of Structures and Machines, 1992
Optimization of holonomic as well as non-holonomic multibody systems is presented as a nonlinear programming problem that can be solved with general-purpose optimization codes. The adjoint variable approach is used for calculating design derivatives of a rather general integral type performance measure with respect to design parameters.

The Challenges and Achievements of Experimental Implementation of an Active Transfemoral Prosthesis Based on Biological Quasi-Stiffness: The CYBERLEGs Beta-Prosthesis

Frontiers in Neurorobotics, 2018
The CYBERLEGs Beta-Prosthesis is an active transfemoral prosthesis that can provide the full torque required for reproducing average level ground walking at both the knee and ankle in the sagittal plane. The prosthesis attempts to produce a natural level

On the Modeling of Shells in Multibody Dynamics [PDF]

Volume 6A: 18th Biennial Conference on Mechanical Vibration and Noise, 2001
Abstract Energy preserving/decaying schemes are presented for the simulation of the nonlinear multibody systems involving shell components. The proposed schemes are designed to meet four specific requirements: unconditional nonlinear stability of the scheme, a rigorous treatment of both geometric and material non-linearities, exact ...

Research on Dynamic Modeling and Control of Magnetorheological Hydro-Pneumatic Suspension

Actuators
A novel magnetorheological semi-active hydro-pneumatic suspension system was proposed to overcome the shortcoming of the traditional hydro-pneumatic suspension without adaptive vibration damping function. It is based on the magnetorheological semi-active
