RISDead Center Identification of Two-Degrees-of-Freedom Planar Parallel Manipulator Using Graph Theory and Transmission Angle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Parallel manipulators are widely applied for their advantages of high stiffness, load-bearing, operation speed, and precision positioning capabilities, which are required in many industrial applications. However, dead ...
The Perimeter Loop-Based Method for the Automatic Isomorphism Detection in Planetary Gear Trains
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Planetary gear trains (PGTs) are widely used in transmission systems. The structural synthesis of PGTs is an effective way to create novel and excellent transmissions. In the structural synthesis of PGTs, the isomorphism ...
The Complete Set of One-Degree-of-Freedom Planetary Gear Trains With Up to Nine Links
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The structural synthesis of planetary gear trains (PGTs) is helpful for innovating transmission systems in machinery. A great deal of research has been devoted to the synthesis of one-degree-of-freedom (1-DOF) PGTs over ...
Structural Synthesis of Baranov Trusses With Up to 13 Links
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The structural synthesis of Baranov trusses is still an open problem, although Baranov trusses are widely used in the design and analysis of mechanisms and robots. This paper proposes a systematic method for the structural ...
Type Synthesis of Modular Polyhedral Mechanisms Based on the Generalized Mechanism Models of Regular Polyhedron
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An integrated type synthesis method for polyhedral mechanisms based on polyhedron is proposed. The properties of the polyhedron are considered and the corresponding generalized mechanism is built based on strategies that ...
Construction and Multi-Mode Motion Analysis of Single-Degree-of-Freedom Four-Bar Multi-Mode Planar Mechanisms Based on Singular Configuration
