RISDesign and Analysis of 3R2T and 3R3T Parallel Mechanisms With High Rotational Capability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the design, kinematics, and workspace analysis of 3R2T and 3R3T parallel mechanisms (PMs) with large rotational angles about three axes. Since the design of PMs with high rotational capability is still ...
Kinematic Performance and Static Analysis of a Two-Degree-of-Freedom 3-RPS/US Parallel Manipulator With Two Passive Limbs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new 3-RPS (the limb consisting of one revolute, one prismatic, and one spherical joint)/US (universal joint and spherical joint) parallel mechanism with two degrees-of-freedom (DOFs) is obtained by adding ...
Optimal Design of a Kinematically Redundant Planar Parallel Mechanism Based on Error Sensitivity and Workspace
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the dimensional optimization of a (2PRR)-R + 2RRR (P and R represent the prismatic and revolute joint, respectively, and the underline indicates that the joint is the actuator) kinematically redundant parallel ...
A Kinematics-Based Optimization Design for the Leg Mechanism of a Novel Earth Rover
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a general kinematic-based design method for optimizing the side-mounted leg mechanism of BJTUBOT, a novel multi-mission quadrupedal Earth rover. The focus issue lies in designing structural improvements ...
Error Sensitivity Analysis of a 1T2R Kinematically Redundant Parallel Mechanism With Closed-Loop Chain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a generalized method for error modeling of the spatial 1T2R three degrees-of-freedom kinematically redundant parallel mechanism with a closed-loop chain is proposed, which is based on the matrix differential ...
Design and Analysis of a Bimanual Parallel Dexterous Hand With Cooperative Manipulation Capability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A bimanual parallel dexterous hand with cooperative manipulation capability is proposed to solve the problem that one hand cannot achieve continuous in-hand manipulation. The bimanual parallel dexterous hand is composed ...
Design and Kinematical Performance Analysis of a 3 RUS/RRR Redundantly Actuated Parallel Mechanism for Ankle Rehabilitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present the design of a novel 3RUS/RRR redundantly actuated parallel mechanism for ankle rehabilitation based on the principle from the conceptual design. The proposed mechanism can actualize the rotational ...
Design and Control of a Foldable and Reconfigurable Multi-Terrain Vehicle With Variable Wheelbase
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In many rescue and detection tasks, mobile robots are required to transverse over uneven terrains and enter some dangerous environments that people cannot overcome, such as crevices, pipes, gullies, etc. High mobility/speed ...
Modeling, Simulation, and Kinematic Validation of Transfemoral Prosthetic Mechanism With Ankle Varus–Valgus Characteristic
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Inspired by the kinesiology of human bionic joints, a transfemoral prosthetic mechanism based on a functional structure of parallel mechanism is developed for the transfemoral amputees. The walking interactive simulation ...
Analysis of the Rollover Crash Worthiness of the Bus Body Structure Based on ECE R66 Regulation
Publisher: American Society of Civil Engineers
Abstract: Given that dynamic test data are difficult to obtain and relevant test results are always unstable, this study examines the rollover crash worthiness of a 6756-type bus. The finite element model and numerical simulation ...
