RISDesign and Analysis of a Novel Reconfigurable Parallel Manipulator With Kirigami-Inspired Bennett Plano-Spherical Linkages and Angular Pouch Motors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Drawing inspiration from kirigami, this article first presents the crease pattern of a kirigami model which is kinematically equivalent to a Bennett plano-spherical linkage. In terms of the screw theory, distinct closed-loop ...
Computational Fluid Dynamics Based Numerical Analysis of Acoustic Attenuation and Flow Resistance Characteristics of Perforated Tube Silencers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The 3D timedomain computational fluid dynamics (CFD) approach is used to calculate the acoustic attenuation performance of perforated tube silencers without and with flow. For the crossflow perforated tube silencer and ...

An Finite Element Method Study of the Thermal Conductivity of Polycrystalline UO2
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A finite element method (FEM) is applied to investigate the thermal conductivity of polycrystalline UO2. The influences of microstructure are especially important for UO2 due to the severe structural changes under irradiation ...
Characterization of Substrate Materials for System-in-a-Package Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: System-in-a-Package (SiP) aims to integrate the entire system functions within a system-level package containing multiple ICs and other components interconnected in a high-density substrate. A ...
Numerical Investigation of Combustion and Emission With Different Diesel Surrogate Fuel by Hybrid Breakup Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Injection flow dynamics plays a significant role in fuel spray; this process controls the fuel–air mixing, which in turn is critical for the combustion and emissions process in diesel engine. In the current study, an ...
