RISDesign and Analysis of a Symmetric Overconstrained Compliant Tilt/Tip Stage Based on a Hybrid Transmission Ratio Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Developing a compliant mechanism that have potential in parasitism suppression and cross-axis decoupling is a major challenge to meet the requirement of spatial micro-/nano positioning. This work introduces a compliant ...
Model for Public Car Park Layout Based on Dynamic Multiperiodic Parking Demands
Publisher: American Society of Civil Engineers
Abstract: The problem in designing a public car park layout entails selecting several car parks for construction and then determining the assigned number of parking spaces in each selected car park within a planning region containing ...
Design and Analysis of an Active Swing Decoupling Compliant Mechanism With Multiple Co-Directional Input Branches
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, we propose a novel bio-inspired swing decoupling mechanism supporting high precision motion systems, which is composed of multiple co-directional input branches with a rigid swing unit and an anti-rotational ...
Effect of Trailing Edge Modification of a Mixed Flow Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modern pumps are designed to guarantee a sufficiently large operating range or to satisfy the performance requirements relative to more than one operating point. This study applies trailingedge (TE) modification method ...
Field Tests on Deformation Property of Self-Weight Collapsible Loess with Large Thickness
Publisher: American Society of Civil Engineers
Abstract: To study the deformation property of large-thickness self-weight collapsible loess and to understand the moisture migration law and matrix suction characteristics, a 40-m-diameter soaking test was conducted in the field ...
Dynamic Modulus of Staggered Nanocomposites With Different Distributions of Platelets Considering the Interface Stress Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Biological staggered composites, like bone, nacre, and dentin, possess the superior capacity of energy dissipation than that of conventional materials. In these nanocomposites, different staggered microstructures are widely ...
Computational Fluid Dynamics-Based Pump Redesign to Improve Efficiency and Decrease Unsteady Radial Forces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a double volute centrifugal pump with relative low efficiency and high vibration is redesigned to improve the efficiency and reduce the unsteady radial forces with the aid of unsteady computational fluid ...
Second-Law Thermodynamic Comparison and Maximal Velocity Ratio Design of Shell-and-Tube Heat Exchangers With Continuous Helical Baffles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Shell-and-tube heat exchangers (STHXs) have been widely used in many industrial processes. In the present paper, flow and heat transfer characteristics of the shell-and-tube heat exchanger with ...
Untitled
Publisher: American Meteorological Society
Abstract: AbstractA new version of the Global Ensemble Forecast System (GEFS, v11) is tested and compared with the operational version (v10) in a 2-yr parallel run. The breeding-based scheme with ensemble transformation and rescaling ...
Influence of Reservoir Water Levels on the Protective Performance of Concrete Gravity Dams Subjected to Underwater Explosions
Publisher: American Society of Civil Engineers
Abstract: Blast loads would cause serious damage to concrete gravity dams, and a possible dam break can lead to a catastrophe in downstream populated areas. Preventing damage to dam structures is of great interest in the blast-resistant ...
