Dynamic Modeling and Analysis of a Flying–Walking Power Transmission Line Inspection Robot Landing on Power Transmission Line Using the ANCF Method

Applied Sciences
To enhance the safety of hybrid inspection robots (HIRs) landing on power transmission lines (PTLs) with inclination and flexibility, this research derives a coupled dynamic model for a developed flying–walking power transmission line inspection robot ...

Aerothermoelastic analysis of panel flutter based on the absolute nodal coordinate formulation

, 2014
Panels of reentry vehicles are subjected to a wide range of flow conditions during ascent and reentry phases. The flow can vary from subsonic continuum flow to hypersonic rarefied flow with wide ranging dynamic pressure and associated aerodynamic heating.

A two-dimensional shear deformable ANCF consistent rotation-based formulation beam element.

, 2016
It has been demonstrated recently that the absolute nodal coordinate formulation (ANCF) can be used to develop lower-order consistent rotation-based formulations (CRBFs) that employ finite rotation parameters as nodal coordinates without the need for ...
