RISMonitoring Cutting Forces In Turning: A Model-Based Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The importance of monitoring the cutting force in the turning process has been well recognized in industry as well as in the open literature. This paper proposes a cutting force monitoring ...
A Non-Normality Measure of the Condition Number for Monitoring and Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Because the behavior of the condition number can have highly steep and multi-modal structure, optimal control and monitoring problems based on the condition number cannot be easily solved. In ...
A Quantitative Performance Index for Observer-Based Monitoring Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Model-based monitoring systems based on state observer theory are attractive for machine monitoring because practical, inexpensive, and reliable sensors can be located remote to the signal(s) of ...
Estimation of Gear Backlash: Theory and Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Machine and product condition monitoring is important to product quality control, especially for unmanned manufacturing. This paper proposes a technique for the estimation of clearance in mechanical ...
Model Error Compensation for Bearing Temperature and Preload Estimation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple to apply, two-step observer design methodology is developed for a general class of systems with model uncertainty. This approach is applied to estimate bearing internal temperatures and ...
On-Line Preload Monitoring for Anti-Friction Spindle Beatings of High-Speed Machine Tools
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Catastrophic and premature bearing failure caused by excessive thermally-induced bearing preload is a major design problem for spindle bearings in high-speed machine tools. Due to a lack of low ...
Discrete-Time Well-Conditioned State Observer Design and Evaluation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Model-based monitoring systems based on state observer theory often have poor performance with respect to accuracy, bandwidth, reliability (false alarms), and robustness. The above limitations are ...
Energy-Based Model Reduction Methodology for Automated Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In recent years, algorithms have been developed to help automate the production of dynamic system models. Part of this effort has been the development of algorithms that use modeling metrics ...
An Input-Output Criterion for Linear Model Deduction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Model order deduction algorithms have been developed in an effort to automate the production of accurate, minimal complexity models of dynamic systems in order to aid in the design of these ...
Realization-Preserving Structure and Order Reduction of Nonlinear Energetic System Models Using Energy Trajectory Correlations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous work by the authors developed algorithms for simplifying the structure of a lumped dynamic system model and reducing its order. This paper extends this previous work to enable simultaneous ...
