RISContact Kinematics in the Roller Screw Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the nature of the contact between the load transferring surfaces in the roller screw mechanism, i.e., between the screw and roller threads and between the nut and roller threads. The analysis is ...
Impact of Non-Uniform Surface Temperature on the Apparent Radiative Properties of Cavity Receivers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Radiative surface properties play a critical role in the design, analysis and optimization of solar–thermal systems. Cavity receivers increase the efficiency of solar–thermal energy systems through the cavity effect. The ...
Perspective: Driving Electric Vehicle Battery Design With Atomistic Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Electric vehicles (EVs) continue to increase their share of the automotive market. To spur this growth, original equipment manufacturers (OEMs) and battery cell manufacturers have invested in atomistic modeling ...
Dynamics of the Planetary Roller Screw Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper develops the dynamic equations of motion for the planetary roller screw mechanism (PRSM) accounting for the screw, rollers, and nut bodies. First, the linear and angular velocities and accelerations of the ...
Evaluation of a Mesoscale Short-Range Ensemble Forecast System over the Northeast United States
Publisher: American Meteorological Society
Abstract: A short-range ensemble forecast system was constructed over the northeast United States down to 12-km grid spacing using 18 members from the fifth-generation Pennsylvania State University?National Center for Atmospheric ...
Reduced Order Modeling of Conjugate Heat Transfer Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the application of reducedorder modeling techniques in the simulation of conjugate heat transfer processes. In a reducedorder model (ROM), the dominate features of a system are represented using a ...
Dynamic Control of Radiative Surface Properties With Origami Inspired Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal management systems for space equipment commonly use static solutions that do not adapt to environmental changes. Dynamic control of radiative surface properties is one way to respond to environmental changes and ...
Reducing Cloud Contamination in ATSR Averaged Sea Surface Temperature Data
Publisher: American Meteorological Society
Abstract: The Along Track Scanning Radiometer (ATSR) was launched in July 1991 on the European Space Agency's first remote sensing satellite ERS-1. ATSR has the potential to measure sea surface temperature (SST) to a precision of ...
Spectral Absorption Coefficient of Additive Manufacturing Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Active thermography techniques are of interest for quality assurance of additive manufacturing processes. However, accurate measurements of thermophysical properties of materials are required to successfully implement ...
