为提升梁式桥的抗震性能,实现桥梁结构在地震作用下力学行为的可控性,基于减隔震设计原理,研发了一种功能可控型减隔震支座.通过数值模拟和模型试验研究了该支座的力学行为,结果表明:支座的滑动性能良好,摩擦行为稳定;剪力销力学行为可控,断后摩擦行为正常;环形钢阻尼元件滞回曲线饱满,耗能能力强;可控型支座整体力学行为稳定可控.最后以某3跨桥梁为例分析了可控型支座的减隔震效果,结果表明:合理选用可控型支座可以实现结构在地震作用下力学行为的可控性,使结构响应在力和位移之间取得较好的平衡,从而达到避免桥墩损伤破坏、防止落
This paper describes a novel gait pattern recognition method based on Long Short-Term Memory (LSTM) and Convolutional Neural Network (CNN) for lower limb exoskeleton.The Inertial Measurement Unit (IMU) installed on the exoskeleton to collect motion inform
Individuals with cerebral palsy and muscular dystrophy often lack fine motor control of their fingers which makes it difficult to control traditional powered wheelchairs using a joystick.Studies have shown the use of surface electromyography to steer powe
The bio-inspired aerial-aquatic vehicle offers attractive perspectives for future intelligent robotic systems.Cormorant\'s webbed-feet support water-surface takeoff is a typical locomotion pattern of amphibious water birds,but its highly maneuver-able a
Gecko has the ability to climb flexibly on various natural surfaces because of its fine layered adhesion system of foot,which has motivated researchers to carry out a lot of researches on it.Significant progresses have been made in the gecko-like dry adhe
Soft robots have unique advantages over traditional rigid robots and have broad application prospects in many fields.To expand their bioinspired applications,we propose a novel Soft Pneumatic Actuator (SPA) associated with spiral configura-tion inspired b
Venus flytrap can sense the very small insects that touch its tactile receptors,known as trigger hairs,and thus capture prey to maintain its nutrient demand.However,there are few studies on the trigger hair and its morphological structure and material pro
Unexpected ice accumulation tends to cause many problems or even disasters in our daily life.Based on the superior elec-trothermal and photothermal function of the carbon nanotubes,we introduced a superhydrophobic/electrothermal/photo-thermal synergistica
The structural characteristics of the surfaces of sharkskin have great influence on their aerodynamic performance.It has been proved that the sharkskin\'s ribbed structure can improve the aerodynamic performance of the parts up to 10％.At present,the mai
Polyvinyl alcohol (PVA) hydrogels with excellent characteristics are considered as promising cartilage replacement materials.However,there are still some main issues to be solved for PVA hydrogel,such as poor mechanical strength and disordered structure.I
