RISVirtual Clay: An Enhanced Marching Cubes Algorithm for In-Process Geometry Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an enhanced marching cubes algorithm to construct an iso-boundary for in-process geometric modeling for material removal processes. The author first analyzes the tool motion ...
Dynamic Stability Analysis of a Two-Link Force-Controlled Flexible Manipulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigates the effect of link flexibility on the dynamic stability of a two-link force-controlled robot manipulator. The nonlinear open-loop equations for the compliant motion are ...
Polynomial Definiteness and Semidefiniteness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A reduction procedure is described for determining the sign definiteness and semidefiniteness of an mth order, n dimensional real polynomial. The higher order polynomial is reduced to a quadratic ...
Effect of Normal Stiffness in Loading System on Wear of Carbon Steel—Part 2: Dynamic Normal Load and Effective Sliding Distance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to explain the effect of normal stiffness in the loading system on wear, the mean dynamic normal load and the effective sliding distance were determined from the record of dynamic ...
Four-Terminal Measurement and Simulations for Sheet Resistance in Piezoresistive Sensing Elements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We have seen some wafers rejected with abnormally large within-wafer variation for the input resistance (Rin) of the X-ducer in the pressure sensing element. Input resistance consists of p+,p−, ...
Effect of Normal Stiffness in Loading System on Wear of Carbon Steel—Part 1: Severe-Mild Wear Transition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is shown that the severe-mild wear transition and the wear rate of 0.45 percent carbon steel pair in dry friction is greatly influenced by the change of normal stiffness from 1 N/mm to ...
Displacement Ductility Capacity Assessment for a Fixed-Head Pile in Cohesionless Soil
Publisher: American Society of Civil Engineers
Abstract: This study develops assessment formulas for the displacement ductility capacity of a fixed-head pile in cohesionless soils. The derivations of the formulas are based on an ideal model of a semiinfinite nonlinear pile in a ...
Humidity-Induced Voltage Shift on MEMS Pressure Sensors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The pressure sensor is one of the major applications of microelectromechanical systems (MEMS). An absolute pressure sensor utilizes anodic bonding to create a vacuum cavity between the silicon ...
Modeling and Vibration Analysis of Spinning-Disk and Moving-Head Assembly in Computer Storage Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Vibration of a spinning disk subject to a moving head, that is frequently encountered in computer storage system, is studied. The magnetic head moving on the spinning disk is modeled as a ...
Tracking Dynamics of In-line Suspensions in High-Performance Rigid Disk Drives with Rotary Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The laser Doppler interferometric modal measurement technique is combined with finite element analysis to study the dynamics of in-line suspensions under actual operating conditions in commercially ...
