RISAn Approach for the Lightweight Design of a 3-SPR Parallel Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A hierarchical approach for the lightweight design of a 3-SPR parallel mechanism (PM) is presented in this paper. The criterion to match the rigidities of the limb body and those of the joints is proposed; meanwhile, the ...
Generalized Radial Basis Function-Based High-Dimensional Model Representation Handling Existing Random Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The radial basis function-based high-dimensional model representation (RBF–HDMR) is very promising as a metamodel for high dimensional costly simulation-based functions. But in the modeling procedure, it requires well-structured ...
Approach for Identifying Cartesian Stiffness of a 5-Degree-of-Freedom Hybrid Robot for Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article presents a systematic approach for identifying the Cartesian stiffness of a 5-degree-of-freedom (DOF) hybrid robot for machining that includes a parallel mechanism and an A/C wrist. The novelty of this approach ...
An Approach for Computing the Transmission Index of Full Mobility Planar Multiloop Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An approach for the force/motion transmissibility analysis of full mobility planar multiloop mechanisms (PMLM) is proposed in this paper by drawing on the duality of twist space and wrench space. By making a comparison ...
A Robust Error Pursuing Sequential Sampling Approach for Global Metamodeling Based on Voronoi Diagram and Cross Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Surrogate models are widely used in simulationbased engineering design and optimization to save the computing cost. The choice of sampling approach has a great impact on the metamodel accuracy. This article presents a ...
An Adaptive Bayesian Sequential Sampling Approach for Global Metamodeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computer simulations have been increasingly used to study physical problems in various fields. To relieve computational budgets, the cheaptorun metamodels, constructed from finite experiment points in the design space using ...

Modeling and Experimental Studies on Vibration-Induced Force Reduction During Needle Insertion of Thin Tissues
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Needle insertion of thin tissues is a crucial procedure in invasive biomedical operations. Reducing the interaction force during needle insertion could yield benefits such as avoiding tissue damage caused by overstretch ...
A Dual Space Approach for Force/Motion Transmissibility Analysis of Lower Mobility Parallel Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By drawing on the duality of twist space and wrench space, this paper presents a general and systematic approach for force/motion transmissibility analysis of lower mobility nonredundant and nonoverconstrained parallel ...
