RISEnvelope Surface Modeling and Tool Path Optimization for Five Axis Flank Milling Considering Cutter Runout
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cutter runout is a common and inevitable phenomenon impacting the geometry accuracy in the milling process. However, most of the works on tool path planning neglect the cutter runout effect. In this paper, a new approach ...
Neural Network Emulation of Inverse Dynamics for a Magnetorheological Damper
Publisher: American Society of Civil Engineers
Abstract: The dynamic behavior of a magnetorheological (MR) damper is well portrayed using a Bouc–Wen hysteresis model. This model estimates damper forces based on the inputs of displacement, velocity, and voltage. In some control ...
Experimental Study of an Adaptive Extended Kalman Filter for Structural Damage Identification
Publisher: American Society of Civil Engineers
Abstract: An objective of the structural health monitoring system is to identify the state of the structure and to detect the damage when it occurs. Analysis techniques for damage identification of structures, based on vibration ...
An Accurate Method for Determining Cutter-Workpiece Engagements in Five-Axis Milling With a General Tool Considering Cutter Runout
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cutter runout is universal and inevitable in milling process and has a direct impact on the shape of the in-process geometry. However, most of the works on the cutter-workpiece engagement (CWE) extraction neglect the cutter ...
Mechanistic Modeling of Five-Axis Machining With a Flat End Mill Considering Bottom Edge Cutting Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In five-axis milling, the bottom edge of a flat end mill is probably involved in cutting when the lead angle of tool axis changes to negative. The mechanistic model will lose accuracy if the bottom edge cutting effect is ...
Adaptive Fuzzy Control for Nonlinear Building-Magnetorheological Damper System
Publisher: American Society of Civil Engineers
Abstract: Because of their intrinsically nonlinear characteristics, development of control strategies that are implementable and can fully utilize the capabilities of semiactive control devices is an important and challenging task. ...

Abstract: Block-wise use of TOPMODEL with the Muskingum–Cunge method (BTOPMC) is a physically based distributed hydrological model with five parameters that quantitatively reflect basin physical features, including soil type, ...
Numerical Investigation on a New Concept of Shock Vector Control Nozzle
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Shock vector control (SVC) based on transverse jet injection is one of the fluidic thrust vectoring (FTV) technologies, and is considered as a promising candidate for the future exhaust system working at high nozzle pressure ...
Flow Characteristics of Double Serpentine Convergent Nozzle With Different Inlet Configuration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Serpentine nozzles have been used in stealth fighters to increase their survivability. For real turbofan aero-engines, the existence of the double ducts (bypass and core flow), the tail cone, the struts, the lobed mixers, ...
