Shaping Liquid Crystal Rubbers by Chemical Potential Gradient

open access: yesMacromolecular Rapid Communications, EarlyView.
Depositing a low molecular weight liquid crystal drop onto a uniformly aligned LCE leads to non‐uniform swelling, enabling temporary shape changes and bending actuation. These deformations are quantitatively modeled for different alignment conditions, and methods to permanently lock desired shapes are explored.

Design, Analysis, and Experimental Validation of a Variable‐Gap Magnetorheological Damper for Seat Suspension

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT To address the dual challenges of routine driving vibration and impact loads in vehicle seat suspensions, a novel variable‐gap magnetorheological damper (VGMRD) is proposed. By combining a tapered piston with a conformal variable‐diameter cylinder, stroke‐dependent, dual‐mode damping characteristics are achieved without the need for complex ...

Detecting Loosening of Bolt‐Flanged Pipe Using Smoothed Pseudo Wigner–Ville Distribution: Digital Twin‐Based Approach Using Convolution Neural Networks

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this paper, an integrated digital twin‐based fault‐diagnosis framework is proposed to detect bolt loosening in flanged pipe connections. The approach combines finite element‐based numerical modeling, experimental modal analysis, and advanced signal processing‐assisted deep learning to achieve reliable loosening detection under operational ...
