This paper proposes the 'skin effect' of machining-induced damage at high strain rates. The first reviews published research work on and then identifies governing factors that dominate formation mechanisms. Among many influential factors, such as stress–strain field, temperature material responses to loading rate, crack initiation propagation, rate is recognized a dominant factor can directly lead in process. elucidates deformation rates (>103 s−1) leads embrittlement, which turn contributes...
In sEMG-based recognition systems, accuracy is severely worsened by disturbances, such as electrode shifts doffing/donning. Traditional models are fixed or static, with limited abilities to work in the presence of disturbances. this paper, a transfer learning method proposed reduce impact shifts. method, novel activation angle introduced locate electrodes within polar coordinate system. An adaptive transformation utilized correct electrode-shifted sEMG samples. The based on estimated...
High-ductility materials often impose grinding problems. This study carries out high-speed on the Al6061T6 alloy at a linear speed of 30.4–307.0 m/s to explore surface integrity and material removal mechanisms from perspectives embrittlement damage skin effect. The results reveal that micrograins are refined into equiaxed nanograins in workpieces subjected grinding. Continuous dynamic recrystallization is induced decreasing depth with an increasing due high strain-rate field reduced heat...
Single-crystal silicon is an important material in the semiconductor and optical industries. However, being hard brittle, a wafer vulnerable to subsurface cracks (SSCs) during grinding, which detrimental performance lifetime of product. Therefore, studying formation SSCs for optimizing SSC-removal processes thus improving surface integrity. In this study, statistical method used study induced grinding wafers. The results show that grinding-induced are not stochastic but anisotropic their...
Abstract Inconel 718 (IN718) alloy is widely applied to fabricate high temperature resistant or corrosion parts due its excellent mechanical performance. However, the machining of IN718 difficult as it may cause serious tool wear and poor surface quality (SQ) workpiece. In this work, grinding experiments on at different speeds were conducted by using a CBN wheel. The relationship between speed, SQ subsurface damage (SSD) was well studied. With increasing roughness decreased, greatly...
A sliding-mode control based on a prescribed performance function is proposed for discrete-time single-input single-output systems. The controller design aims to maintain the tracking error in predefined convergence zone described by function. However, due fixed structure of controller, applicability and universality this method are limited. To address issue, we separate into two parts analyze principle (PPC) method. Then can replace linear part with model-based methods adapt specific...
In this paper, an active modeling and control scheme is developed for Shape Memory Alloy (SMA) actuators to eliminate the negative influences caused by uncertainties in its dynamics. First, a nonlinear SMA dynamic model based on Liang empirical models built linearized, all due time-varying parameters, external disturbances, as well linearization, are considered error of linearized model. Secondly, Kalman filter constructed estimate real time, which intends improve accuracy actively. Finally,...
Soft exoskeletons have demonstrated the potential to save energy, but their efficiency is sensitive variations in human gait cadence. This work aims develop adaptive state detection and iterative force control methods for a soft exoskeleton reduce walking metabolic cost consistently, while user may change The proposed approach motivated by rhythmicity of applies an learning concept enhance exoskeleton's adaptability varying conditions. method designed combines two feature extraction...
When applying exoskeletons for walking assistance, one important consideration is to ensure that the users retain full control over exoskeleton-provided which quite limited in existing due absence of a suitable system. In this article, time-independent exoskeleton system developed based on novel assistance profile generation method and an iterative force enable continuous adjustment. The formulated as Gaussian function with human state variable can be updated online adapt different users....
The success of the Beijing Winter Olympics and Paralympics epitomized vision a community with shared future for humankind.

With coexisting-cooperative-cognitive robots gradually appearing in daily life, an instinct and efficient human-robot interaction (HRI) is becoming more challenging necessary. Surface electromyography (sEMG) signals, as one of mainstream manners the interactions, are employed to predict human intentions. In this paper, provide natural assistance for standing up sitting down, sEMG signals acquired from active muscles one's lower limb utilized continuous movements. A temporally smoothed...
