Nonparallel Plane Distance Measurement and Error Analysis System Based on LabVIEW
The traditional method of measuring the thickness of the airbag isolator gasket involves manually measuring the gap between the metal mounting surface and subtracting the isolator height. This method has problems with low efficien-cy and insufficient accuracy. Therefore,a non-parallel plane distance measurement and error analysis system based on Lab-VIEW is designed. A measurement device with a simple structure and high measurement accuracy is designed based on the eddy current displacement sensor. The sensor simultaneously acquires measurement data from multiple measurement points and uploads it to the host computer. A LabVIEW program is written to display,process,and store the measurement data in real-time and calculate the distance between the metal surfaces. The particle swarm algorithm is used to calculate the flat-ness of the measured metal panel. Experimental tests show that the device can measure the gap and flatness of metal sur-faces with a measurement error of less than 0.02mm. It can be applied to non-parallel metal surface distance and error measurement and has practical value.
