Research Regarding Manufacturing Process of an Electronic Hybrid Polymer Structure. Design and Technologies for Polymeric and Composites Products

Macromolecular Symposia, EarlyView.
ABSTRACT An electronic hybrid polymer structure represents a product that combines polymeric materials with electronic properties—by incorporating conductive materials (metals or conductive polymers) or through the interaction with organic semiconductors.

An Improved Air Film Model for Studying the Tilt Characteristics of Aerostatic Thrust Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, an improved mass‐spring model that treats the lubricating air film as distributed springs is proposed to calculate the static and dynamic angular stiffness of aerostatic thrust bearings. The proposed model refines the traditional mass‐spring model by introducing the spatially varying mechanical properties of the air film and the

Fault Detection of Electric Motors via Symmetrized Dot Pattern‐Based Features

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study proposes a novel symmetrized dot pattern (SDP) approach using designed SDP‐based features, extracted from transformed vibration signals, for fault detection. These features describe the compactness, inclination, and shape of the “snowflake” diagram distributions.
