Deep-subwavelength ultra-low and ultra-broadband acoustic-black-hole metamaterials - Nature Communications
Abstract Acoustic black holes (ABHs) offer broadband wave-manipulation capabilities beyond conventional acoustic metamaterials (AMs) but are fundamentally limited by compromised structural stiffness, high-precision machining requirements and high cut-on frequencies. Here, we break these limitations by adopting a power-law density-tailored composite, ρ-ABH.
Efficient Dynamics Modeling and Adaptive Tracking Control for a Rigid‐Flexible Manipulator
Vibration suppression and trajectory tracking are pivotal areas of current robotics research, significantly influencing the operational performance of flexible manipulators. This article proposes a novel dynamics modeling strategy for flexible manipulators based on the multi-body system transfer matrix method, which achieves comparable accuracy to the traditional Lagrange method while improving computational efficiency by approximately 35.5% and 35.9% in two representative cases, respectively.

Modelling and control of magnetorheological hydro-pneumatic suspension system based on multibody system transfer matrix method
Abstract A new type of magnetorheological (MR) hydro-pneumatic suspension (HPSP) system was proposed by introducing MR technology into traditional HPSP system to improve ride comfort and handling stability of vehicles. The dynamics model of MRHPSP system was established based on multibody system transfer matrix method (MSTMM), and an effective control method was designed. Firstly, the mechanical properties of the MR hydro-pneumatic (HP) spring were tested.

Design, Modeling, and Vibration Control of a Damper Based on Magnetorheological Fluid and Elastomer
1. Introduction The engine is one of the main vibration sources of the vehicle system [1]. Reducing the transmission rate of the vibration generated by the engine to the vehicle body not only improves the ride comfort of the occupants but also protects the precision components in the vehicle to a certain extent [1,2,3,4]. In addition to the function of vibration isolation, the engine mount system also plays a role in bearing and limiting.
