RISReduction of Instrumented Linkage Data for Simple Anatomical Joint Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When measuring the total, six degree-of-freedom (dof) motion permitted by an anatomical joint, it is convenient to attach the ends of an instrumented linkage to the two bodies meeting at the ...
A Hybrid Approach to Solving the Position Equations for Planar Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a straightforward approach is developed to solve the nonlinear position equations for a linkage when a closed-form solution to some of the equations can be obtained. This is ...
Joint Models, Degrees of Freedom, and Anatomical Motion Measurement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When the motion associated with an anatomical joint is to be measured, a kinematic model for the joint must first be established. The joint model will have from one to six degrees of freedom, ...
A Comparison of the Performance of Nonlinear Equation Solvers for Machine Design Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Often, the mathematical modeling of mechanical components leads to a set of nonlinear equations which have to be solved in order to compute the design variables. This paper discusses the ...
Kinematic Transformation Matrices for 3D Surface Contact Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A generalized procedure is presented for the development of a pair matrix that describes kinematic joints formed by contact between three-dimensional surfaces. The pair matrix is useful in the ...
Engineering Constraint Management Based on an Occurrence Matrix Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In many mechanical systems, the mathematical model can be characterized by m nonlinear equations in n unknowns. The m equations could be either equality constraints or active inequality constraints ...
Rectified Synthesis of Six-Bar Mechanisms With Well-Defined Transmission Angles for Four-Position Motion Generation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a rectified synthesis method where a rigid body of a six-bar linkage with well-defined transmission angles is guided to pass through four precision positions. The procedure ...
Bottom End-Closure Design Optimization of DOT-39 Non-Refillable Refrigerant Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study addresses the problem of stability (standing of cylinders upright) of DOT-39 nonrefillable refrigerant cylinders using both experimental and finite element analysis (FEA) approaches. ...
Determination of Burst Pressure and Location of the DOT-39 Refrigerant Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The burst pressure of DOT-39 refrigerant cylinders is determined using both experiment and finite element analysis (FEA) approaches. The experimental burst test investigations were carried out by ...
Minimum Material Design for Propane Cylinder End Closures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study addresses the design of DOT-4BA refillable cylinders using both experimental and numerical approaches. Using traditional design methods, these cylinders often experience buckling on the ...
