Multibody system transfer matrix method: The past, the present, and the future

International Journal of Mechanical System Dynamics, Volume 2, Issue 1, Page 3-26, March 2022., 2022
Abstract The multibody system transfer matrix method (MSTMM), a novel dynamics approach developed during the past three decades, has several advantages compared to conventional dynamics methods. Some of these advantages include avoiding global dynamics equations with a system inertia matrix, utilizing low‐order matrices independent of system degree of ...

Development of steady arm damper for electrified railway overhead contact line with double pantographs based on numerical and experimental analysis

IET Electrical Systems in Transportation, Volume 11, Issue 3, Page 269-277, September 2021., 2021
Abstract To improve the carrying capacity, double pantographs are normally used to collect the electric current from the catenary. The mechanical wave excited by the leading pantograph affects the contact of the trailing pantograph and the contact wire, which usually deteriorates the current collection quality.

Stable Inversion for Flexible Multibody Systems Using the ANCF

Proceedings in Applied Mathematics and Mechanics, Volume 20, Issue 1, January 2021., 2021
Abstract Flexible robots are often non‐minimum phase systems. Thus, their inverse model must be computed by stable inversion. Here, a simplification to the stable inversion process is proposed, which enables its application to complex underactuated multibody systems.

A Comparative Study on the Wind Deflection of Railway Overhead Contact Line Based on Empirical Formula and Finite Element Approach

Shock and Vibration, Volume 2021, Issue 1, 2021., 2021
The assessment of wind deflection of the railway overhead contact line (OCL) is of great importance to ensure the safe and reliable operation of the electrified railway. This paper performs a comparative study of the railway OCL wind deflection based on the traditional empirical formula and finite element method (FEM).

Adaptive Control of Space Robot Despinning Tumbling Target Using Flexible Brushes

International Journal of Aerospace Engineering, Volume 2021, Issue 1, 2021., 2021
A flexible brush mechanism is designed and mounted at the end of a seven‐degree‐of‐freedom robotic arm to despin a tumbling target. The dynamics model of the flexible brush is established using the absolute nodal coordinate method (ANCF), and its contact collision with the solar wing of the tumbling target is analysed.
