RISSpecial Issue: Geometric Tolerancing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In 1989 a small group of researchers gathered at Jerusalem, Israel under the sponsorship of CIRP (International Academy for Production Engineering) to address the emerging problem of computeraided tolerancing (CAT), which ...
Application of Quasi Monte Carlo Method Based on Good Point Set in Tolerance Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tolerance analysis is increasingly becoming an important tool for mechanical design, process planning, manufacturing, and inspection. It provides a quantitative analysis tool for evaluating the effects of manufacturing ...
The Strategy of Datum Reference Frame Selection Based on Statistical Learning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A datum selection strategy based on statistical learning is proposed. The datum selection is an important part of tolerance specification which is the base of geometric tolerance selection and tolerance principle selection. ...
Form Defects Consideration in Polytope-Based Tolerance Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The polytope-based tolerance analysis in design process uses a finite set of constraints to represent specifications and propagates these constraints to any objective point in the Euclidean space. The operations of Minkowski ...
Flow Pattern Analysis and Heat Transfer Characteristics During Subcooled Flow Boiling in a Rectangular Microchannel on ZnO Microrod Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The combination of microstructured surface and microchannel flow boiling is expected to solve the thermal management problems of high-heat-flux devices. In this study, the experimental investigation of subcooled flow boiling ...
Onset of Boiling, Heat Transfer, and Flow Patterns of Flow Boiling on the Superhydrophobic Porous Copper Surface in a Microchannel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To explore the effect of microstructured porous surface on enhancing the heat transfer of flow boiling in a microchannel, the microporous copper surface was fabricated with microscale pores in ranges of 1–5 μm, which ...
A Digital Twin-Based Method for Assembly Deviations Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes and develops a digital twin-based method for assembly deviation analysis, which considers the impact of product shape deviations and uses assembly data in the product design phase to enhance the performance ...
Flow Boiling Heat Transfer in Enhanced Tubes With Composite Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To fill the research gaps in the study of flow boiling on composite surfaces, four heat exchange tubes with different structures were investigated: an enhanced tube with herringbone teeth (EHT_HB), a tube with a dimple ...
Condensation Heat Transfer Experiments of R410A and R32 in Horizontal Smooth and Enhanced Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A horizontal smooth copper tube and two enhanced tubes (a dimpled tube and a diamond-shaped tube) with a length of 2 m and an outer diameter of 9.52 mm were studied in a two-phase condensation experiment using R410A and ...
