RISPrestall Disturbances and Stall Inception for an Eccentric Low-Speed Axial Compressor With Inlet Swirl
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Owing to the manufacturing and assembly error or the fatigue of long-time operation, nonaxisymmetric tip clearance is actually a common phenomenon in compressors. It is also well accepted that tip leakage flow, associated ...
An Efficient Decoupled Reliability-Based Topology Optimization Method Based on a Performance Shift Strategy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new efficient reliability-based topology optimization (RBTO) method is proposed for structures, in which the double-loop optimization is equivalently decoupled into a sequential process based on a performance ...
Finite Element Evaluation of Key Approaches to Develop Insensitive Fuze
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper evaluates several key approaches for their impact on the development of insensitive munition (IM) with special emphasis on the fuze. The effect of these approaches on the thermal vulnerability of a fuze is studied ...
Mobility and Kinematic Analysis of Foldable Plate Structures Based on Rigid Origami
Publisher: The American Society of Mechanical Engineers (ASME)
Time-Dependent Reliability Analysis Through Response Surface Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In time-dependent reliability analysis, the first-passage method has been extensively used to evaluate structural reliability under time-variant service circumstances. To avoid computing the outcrossing rate in this method, ...
Positioning Accuracy Reliability Analysis of Industrial Robots Considering Epistemic Uncertainty and Correlation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Uncertainties widely existing in modeling parameters, such as link length, joint clearance, and rotation angle, have the serious impact on the motion performance of industrial robots. In this study, a reliability analysis ...
Kinetostatic Modeling of Dual-Drive H-Type Gantry With Exchangeable Flexure Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flexure joints are proposed to replace the rigid assembly between the cross-arm and the moving carriages of dual-drive H-type gantry (DHG) for higher reliability and fine rotational alignments. In the literature, the ...
A Design Method of Optimum Stable Excavating Angle of Rock Slopes Containing Weak Surfaces and Its Application
Publisher: American Society of Civil Engineers
Abstract: According to the structure characters of rock slopes containing weak surfaces, model of roadbed slope containing weak surfaces is build up, and then a design method based on the limiting equilibrium is established. The ...
Evidence-Based Structural Uncertainty Quantification by Dimension Reduction Decomposition and Marginal Interval Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Evidence theory has the powerful feature to quantify epistemic uncertainty. However, the huge computational cost has become the main obstacle of evidence theory on engineering applications. In this paper, an efficient ...
Research on Improved YOLOv5 Pipeline Defect Detection Algorithm
Publisher: American Society of Civil Engineers
Abstract: The main problem addressed in this research is the detection of three types of defects in underground drainage pipelines: gravel intrusion, obstacles, and foreign objects. To tackle this, improvements have been made by ...
