RISMembrane-Based Forms for Innovative FRP Bridge Systems through Structural Optimization
Publisher: American Society of Civil Engineers
Abstract: The use of fiber-reinforced polymer (FRP) composites for new construction is still limited primarily due to high costs and designs based on shapes best suitable to conventional materials. The layered and fiber dominated ...
Interactive Dimensional Synthesis and Motion Design of Planar 6R Single-Loop Closed Chains via Constraint Manifold Modification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present an interactive, visual design approach for the dimensional synthesis of planar 6R single-loop closed chains for a given rational motion using constraint manifold ...
Identification of Dynamic Parameter of a 3DOF Parallel Manipulator With Actuation Redundancy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the dynamic parameter identification of a 3DOF parallel manipulator with actuation redundancy. A method for finding the parameter linear form of the dynamic equation is ...
Optimal Kinematic Design and Application of a Redundantly Actuated 3DOF Planar Parallel Manipulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper addresses optimal kinematic design and application of a redundantly actuated parallel manipulator with 3DOFs. Based on the kinematic model, the Jacobian matrix is derived and then ...
Dynamic Analysis and Counterweight Optimization of the 2-DOF Parallel Manipulator of a Hybrid Machine Tool
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper focuses on the dynamic modeling and counterweight optimization of the two degree of freedom planar parallel manipulator, which is a subpart of a hybrid machine tool. Based on a ...
On the Extension of a Fourier Descriptor Based Method for Planar Four-Bar Linkage Synthesis for Generation of Open and Closed Paths
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In an earlier work, we have presented an efficient method for synthesizing crank-rocker mechanisms that are capable of generating perceptually simple and smooth low harmonic closed curves. In ...
Toward Stable and Realistic Haptic Interaction for Tooth Preparation Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present the methods to generate a stable and realistic simulator for dental surgery. First, a simplified force model is derived from grinding theory by considering the complex ...
Analysis and Application of a 2-DOF Planar Parallel Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the optimal kinematic design, dynamic analysis, and application of a 2 degree of freedom (2-DOF) planar parallel mechanism. In the optimal kinematic design phase, the ...
Homing Strategy for a Redundantly Actuated Parallel Kinematic Machine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the homing process of a regular parallel kinematic machine (PKM), all servoaxes are independently driven to return to their homing positions. However, in a redundantly actuated PKM, the ...
Fatigue Assessment of Slender Long-Span Bridges: Reliability Approach
Publisher: American Society of Civil Engineers
Abstract: It is well known that wind loads result in wind-induced buffeting of slender long-span bridges. Traffic also frequently exists on a slender long-span bridge simultaneously throughout its service life, which can affect the ...
