RISStudy on the Looseness Caused by Local Slip and Load Bearing Capacity of Threaded Connections Under Transverse Cyclic Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Under transverse cyclic loading, slip will occur on the contact surfaces in a threaded connection, causing rotational loosening of the connection. It is necessary to detect and analyze the loosening behavior of threaded ...
Identification of Physical and Excitation Parameters of Under-Chassis Equipment for Railway Vehicles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The accuracy of the physical parameters and excitation parameters of the under-chassis equipment has a significant impact on investigations of the coupled vibration of the vehicle body and the under-chassis equipment. In ...
The Influence of Needle Eccentric Motion on Hole-to-Hole Injection Characteristics of a Two-Layered Eight-Hole Diesel Injector
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stringent emission regulations diesel engines are required to meet have resulted in the usage of multihole and ultramultihole injectors, nowadays. In this research study, a double-layered eight-hole diesel injection ...
Algorithm for Accumulating Part Mating Gaps to Evaluate Solid and Fluid Performances
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Part mating gaps need to be effectively adjusted during the assembly of products and greatly affect the working performance. This paper develops an algorithm to calculate the dimensional and aerodynamic indexes affected ...
Thermal–Hydraulic–Mechanical Coupling Analysis of Antifreezing Strategies for an Airport Runway Base in a Seasonal Frost Area
Publisher: American Society of Civil Engineers
Abstract: Abstract Frost heave in seasonal freeze–thaw zones poses critical operational risks to airport
runways in cold regions. While gravel cushions, soil stabilization, and insulation
boards are commonly employed, quantitative ...
Zero Curvature Method and Protection Criterion Against Plastic Collapse
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A zero curvature method to estimate the limit load is introduced in detail, and a uniform computing process for computerization of the zero curvature method is presented. A new protection criterion against plastic collapse ...
