Based on deep study on traditional four-wheel alignment parameter testing theory and practical measurement and analysis, combined with the demand of domestic automotive and repair trade and working circumstance, a project in use of PSD measurement、bluetooth communication and database managing customer is proposed.
4. After studied the conformation distortion model of non-metric digital imagery, a distortion parameter testing method based on perspective collineation of two dimensional controlling field (i.e. PT method) has been put forwards, which is the first distortion calibration method for digital cameras in two dimensional controlling field.
The embedded technologybased PDA, virtual instrument technology and trouble diagnosis technology are applied to the field parameter testing and trouble diagnosis of the hydraulic system of engineering machinery. The functional architecture, design and implementation of hardware configuration and software program of the testing device are presented.
In order to meet the measuring requirements of the modern artillery, some technologies of the high precision of image measurement are deeply analyzed and studied in this paper, combined with the scientific research project known as the artillery static parameter testing system.
This image of edge is fit to the parameter testing of three-dimensional braided composites material preform . The research is vital important to analyze mechanical property of three-dimens ional braided composites material.
The parameter testing has shown that the mechanical response predicted by the model agrees well with some experimental data for both the mechanisms of fracture and the parameters that govern the process.
