Method For Calibrating A Mathematical Model

View page
US Patent:
7024343, Apr 4, 2006
Filed:
Nov 30, 2001
Appl. No.:
10/000725
Inventors:
Wissam H. El-Ratal - Sterling Heights MI, US
Assignee:
Visteon Global Technologies, Inc. - Dearborn MI
International Classification:
G06G 7/48
US Classification:
703 6, 703 2, 703 7, 700 98, 356 32
Abstract:
A method is disclosed for calibrating a mathematical model of a component using prototype full-field experimentally collected deformation/strain data. Specifically, the method involves obtaining actual experimental field data using strain sensitive coating material and then mapping said data on a CAD mesh model. The analytical mesh model is then compared to a finite element model that is based on theoretical values referred to as boundary conditions. The finite element model boundary conditions are then calibrated to reflect the values derived from the experimental field measurements. Once calibrated, the model can be used to optimize design of components.

System, Method, And Coating For Strain Analysis

US Patent:
20010008445, Jul 19, 2001
Filed:
Jan 10, 2001
Appl. No.:
09/757943
Inventors:
Peter Ifju - Alachua FL, US
Kirk Schanze - Gainesville FL, US
Yingsheng Wang - Gainesville FL, US
James Hubner - Gainesville FL, US
David Jenkins - Gainessville FL, US
Wissam El-Ratal - Sterling Heights MI, US

International Classification:
G01B011/16
US Classification:
356/032000
Abstract:
The subject invention relates to a strain-sensitive coating, a strain measurement system, and a method to determine strains on substrate materials. In a preferred embodiment of the subject invention, the system includes a luminescent strain-sensitive coating and a strain field mapping system which can be used to create a strain map of the mechanical strain on a substrate material. The luminescent strain-sensitive coating of the subject invention is preferably a polymer-based coating, and can incorporate one or more luminescent compounds. The subject coating can be applied to produce a thin film on a substrate material, such as aluminum, steel, polymer, or composite. One or more characteristics of the luminescence emanating from the coating can then vary in relation to the strain on the substrate material. In a preferred embodiment, the change in the morphology of cracks in the coating can vary one or more characteristics of the luminescence emanating from the coating such that the strain on the substrate material can be determined by measuring the luminescence emanating from the coating.

Method And Apparatus For Measuring Strain Using A Luminescent Photoelastic Coating

US Patent:
20040066503, Apr 8, 2004
Filed:
Apr 4, 2003
Appl. No.:
10/407602
Inventors:
James Hubner - Gainesville FL, US
Peter Ifju - Newberry FL, US
Kirk Schanze - Gainesville FL, US
Shujun Jiang - Xian, CN
Yao Liu - Gainesville FL, US

Wissam El-Ratal - Sterling Heights MI, US
International Classification:
G01B011/16
US Classification:
356/034000
Abstract:
A method and apparatus for measuring strain on a surface of a substrate utilizes a substrate surface coated with at least one coating layer. The coating layer provides both luminescence and photoelasticity. The coating layer is illuminated with excitation light, wherein longer wavelength light is emitted having a polarization dependent upon stress or strain in the coating. At least one characteristic of the emitted light is measured, and strain (if present) on the substrate is determined from the measured characteristic.

US Patent:
20210129853, May 6, 2021
Filed:
Oct 30, 2019
Appl. No.:
16/668478
Inventors:
- Moline IL, US
Nohoon Kl - Cedar Falls IA, US
Wissam H. EL-RATAL - Waterloo IA, US
Rui ZHANG - Waterloo IA, US
Justin T. ROTH - Cedar Falls IA, US
International Classification:
B60W 50/00
G06Q 10/04
A01B 69/04
A01D 41/127
A01B 79/00
G06Q 30/02
Abstract:
A policy map is obtained that includes a first set of machine settings values for controlling a machine to perform an operation at a site, at different locations in the field. An adjustment component receives sensor signals indicating conditions that will be encountered by the machine in the future, as it moves through the site. A cost determination component determines whether an adjustment is to be made to the first set of settings values, based upon the sensor signals. A predictive vehicle model provides an expected vehicle response, based upon the adjusted settings values that are selected. Control signals are generated based upon adjusted setting values that are generated from the policy map, the expected vehicle response, and the future condition sensor signals. The control signal generator generates the control signals to control a set of controllable subsystems.

International Classification:
G01N 3/42
G01N 33/24
Abstract:
A work machine with a chassis, a wheel hub rotationally coupled to the chassis, a tire coupled to the wheel hub and configured to engage an underlying surface, and a controller communicating with a plurality of sensors and having a memory unit. Wherein, the controller stores tire data for the tire in the memory unit and the controller determines a cone index of the underlying surface of the work machine based on the tire data and the plurality of sensors.
