Motion analysis method considering non-smooth contact between an ANCF-based skin model and a rigid body

Nihon Kikai Gakkai ronbunshu
In this study, we propose a motion analysis method for human skin that considers non-smooth contact with rigid objects. The motivation stems from the need for safe and efficient development of human–machine contact systems, particularly in caregiving and

Dynamic Modeling and Active Vibration Control of Piezoelectric Laminated Structure Based on Macrofiber Composite

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
In this paper, a ground‐based experimental system for solar array active vibration suppression has been established. Firstly, in order to establish an accurate model of the solar array, the solar array is regarded as a flexible cantilevered thin plate, and the corresponding dynamical equations are derived using the absolute nodal coordinate method.

Shape Adjustment of a Large Planar Phased Array Antenna With Nonlinear Cable Actuators

International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.
Shape adjustment of large planar phased array antennas is significant because the shape distortion of phased arrays can greatly reduce the antenna’s gain in the observing direction. This study selects the inherent diagonal cables driven by motors as actuators, initially used to improve the stiffness of the antenna structure. The shape adjustment can be
