We present an interferometer of a femtosecond laser for fast full-field 3D surface profilometry. The heterodyne interference is introduced to reduce the requirement of camera's frame rate, thus achieving an enhancement on the measured speed. This method has experimentally demonstrated to increase the measurement speed several fold without significant loss of precision. © Optica Publishing Group 2022, © 2022 The Author(s)

Most underwater vehicles (UV) adjust their attitude depending on the direct thrust of their propellers at different parts or change their course through the rudder during moving at high speed. However, it is hard for the rudder to function at a low speed. This paper introduces the design and control of a UV that can work at various speeds, including the structure design and control method. This UV can adjust the attitude with three rudders. The top rudder controls the left-right heading in high-speed motion. The left and right rudders have two degrees of freedom (DOF), respectively, and the twisting degree of freedom, the same as the conventional rudder, is used to control the ascent and descent during high-speed motion. The unique feature is that the flapping degree of freedom allows the UV to adjust its heading at low speed or hovering, which is challenging with the conventional rudder control method. In this paper, we design an experiment to verify the function of the flapping steering, and the result shows the scheme's feasibility. © Published under licence by IOP Publishing Ltd.

The spatial resolution of conventional Raman distributed optical fiber sensing (RDOFS) systems is fundamentally constrained by the physics principle of optical time domain reflection, which emerges as the primary theoretical limitation. This inherent constraint manifests as progressive pulse broadening along extended sensing distances, confining current kilometer-scale RDOFS implementations to spatial resolutions ranging from several meters to tens of meters. To address this limitation, we proposed and experimentally demonstrated an innovative distributed optical fiber sensing scheme based on incoherent Raman optical frequency domain reflection (IROFDR) employing frequency-space transformation principles. Through systematic investigation of Raman backscattering characteristics generated by sinusoidally modulated laser signals with uniform direct-current-offset stepping along optical fibers, we established a novel optical sensing mechanism. The implemented system achieved breakthrough performance metrics: 10 km sensing distance with 50 cm spatial resolution (0.1 ℃ temperature accuracy), where spatial resolution demonstrates independence from sensing distance and shows deterministic dependence on maximum modulation frequency. This advancement provides a novel approach for high-resolution Raman distributed fiber sensing applications.

Flow structure around a fixed-supported flexible wing during flutter

引用

Experimental Thermal and Fluid Science 2025年 168卷

作者： Peng, Si Alam, Md. Mahbub Zhou, Yu Centre for Turbulence Control Harbin Institute of Technology Shenzhen China School of Mechanical Engineering and Mechanics College of Engineering Eastern Institute of Technology Ningbo China Ningbo Key Laboratory of Numerical Simulation for Advanced Manufacturing Industries China

This work aims to investigate experimentally the flow structure around a flexible wing undergoing flutter. The nominal angle α0 of attack examined is 0° − 10°, and the chord-based Reynolds number Rec is 6.4 × 104 − 1.9 × 105, corresponding to the reduced velocity Ur of 23––70. Three types of flutter are identified, i.e. classical-like (0°−2°), light-stall-like (2°−6°) and deep-stall-like (6° − 8°) flutters, which exhibit features similar to classical, light- and deep-stall flutters associated with spring-supported rigid wings. However, appreciable differences are presently captured in both structural vibration and flow structure between the flexible and rigid wings, which are discussed in detail. Conceptual flow structure models are proposed to summarize the flow structures around the flexible wing undergoing the three types of flutters and their distinct characteristics compared to their counterparts of a rigid wing. Hysteresis phenomena, including dynamic overshoot and undershoot are observed during flutter, and the underlying flow physics is discussed in detail. © 2025 Elsevier Inc.

AgNbO_(3) is an antiferroelectric (AFE) material with double hysteresis loop. Both the antiferroelectricityand ferroelectricity can be enhanced by doping. Herein, the ferroelectricity of AgNbO_(3) ceramics wasenhanced via K-doping and the phase diagram of the (Ag_(1-x)K_(x))NbO_(3) ceramics was upgraded. In details,(Ag_(1-x)K_(x))NbO_(3) ceramics are ferrielectric (FIE) M1 phase as x=5.00-5.50 mol% and ferroelectric (FE) Ophase as x=5.75-6.00 mol% before poling, and FE O phase as x=5.00-6.00 mol% after poling at roomtemperature. With increasing temperature, (Ag_(1-x)K_(x))NbO_(3) ceramics show the phase evolutions from FIEM1, AFE M2 to paraelectric (PE) T phase at x=5.00-5.50 mol% and from FE O, FE T to PE T phase at x=5.75-6.00 mol% before poling, and from FE O, FE T to PE T phase at x=5.00-6.00 mol% after *** d33 values of 180 pC/N and 285 pC/N are obtained at the FE O-FE T and FE T-PE T phase *** work sheds light on a novel and promising lead-free piezoelectric system.

In order to improve the performance of soft actuators, a novel soft actuator is designed, which is driven by a cable. Firstly, the operating principle of this soft actuator is illustrated. Compared with the traditional soft actuators driven by cables, the new designed structure can achieve the forward and reverse bending movements, relying on a single flexible shaft. Secondly, with the help of silicone rubber and 3D printed molds, a fabrication process of the actuator is developed. Thirdly, to verify the bending property, the finite element method is proposed. Some key factors causing the problems of repeatability and hysteresis are analyzed with the results of simulation and experiments. Finally, the grasping tests are carried out, and the integrated soft robotic gripper demonstrates the ability of grasping objects in different shapes and sizes. Due to its high universality and flexibility, this soft actuator shows great potential in industrial manufacturing and medical equipment. © 2020 Journal of Beijing Institute of technology
