NON-CONTACT MEASUREMENT OF GEOMETRICAL PARAMETERS IN LANDING GEAR USING THE HANDHELD 3D LASER SCANNER
Journal Title: Journal of KONES - Year 2014, Vol 21, Issue 3
Abstract
Laser 3D scanners are becoming widely used in many industrial branches. They can be used for prototyping, moulds' designs, special tools creation, reverse engineering, quality control. Also in medicine have been used in the generation of digital 3D files body parts or prosthetic. They are also used in diagnostics to analyse the wear of machine parts, deformation analysis of composite structures, creation of digital objects for FEA analysis. The article includes a description of the noncontact method of geometry measurement using handheld 3D laser scanner REVscan based on geometrical measurements of the MIG-29 aircraft landing gear example. During the analysis performed a complete scan of the landing gear with a resolution of 2 mm (accuracy of 0.05 mm) and a scan of critical points with a resolution of 0.2 mm (0.05 mm accuracy). Subsequently, an attempt to determine the position of characteristic points of connections is by editing the resulting cloud of points. During measurements has been shown the advantages, disadvantages and limitations in the use of non-contact method using 3D laser scanners. Collected data was used to find characteristic point of landing gear in main reference system. Two computer programs were used for data processing. First VXelements software is used to calibration, configuration of the scanner and collecting data. SecondGeomagic 3D software allows extensive data processing.
