Adaptive Nonlinear Sliding Mode Control of Mechanical Servo System With LuGre Friction Compensation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the parameter identification and control problem are investigated for a mechanical servo system with LuGre friction. First of all, an intelligent glowworm swarm optimization (GSO) algorithm is developed to ...
Micromechanical Modeling of Viscoplastic Behavior of Laminated Polymer Composites With Thermal Residual Stress Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a multiscale approach has been developed for investigating the ratedependent viscoplastic behavior of polymer matrix composites (PMCs) with thermal residual stress effect. The finitevolume direct averaging ...
Coupled and Self Adaptive Under Actuated Finger With a Novel S Coupled and Secondly Self Adaptive Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a novel underactuated (UA) finger with first coupled and secondly selfadaptive (COSA) grasping mode. COSA fingers can adaptively grasp objects with different sizes and shapes while its motions during ...
Construction Control Techniques of Long-Span Steel Truss Arch Bridges
Publisher: American Society of Civil Engineers
Abstract: With Wanzhou Yangtze River Bridge as an engineering example, FEM is applied to simulate the whole bridge construction process to optimize the truss member assembling sequences and determine the critical member bars that ...
Optimization of the Hydrodynamic Performance of a Wave Energy Converter in an Integrated Cylindrical Wave Energy Converter-Type Breakwater System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wave energy converters (WECs) are built to extract wave energy. However, this kind of device is still expensive for commercial utilization. To cut down the cost of WECs by sharing the construction cost with breakwaters, ...
Novel Robotic Manipulator With Four Screws for Automated Storage and Retrieval System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With a new perspective, this paper integrates the concept of automated storage and retrieval system (AS/RS) in production and distribution with highthroughput screening (HTS) system and strikes out a new path in designing ...
Inertial Measurement Unit-Based Optimization Control of a Soft Exosuit for Hip Extension and Flexion Assistance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The optimization of the assistive force of a soft exosuit is crucial to the assistive effect. In this paper, an inertial measurement unit (IMU)-based optimization controller was designed to provide effective hip extension ...
