Analysis of Laser Triangulation Technique Applied to Experimental Deformation of Farm Machinery Elements

Abstract

Deformation intensity analysis for mechanical parts are datas very important for machine design. For farm machines, these parameters demonstrate difficulties for determination due particularities. Machinery industry search for advanced technologies for development and optimization to determine parts mechanical behavior. This research work presents the analysis of the reliability in the application of the laser triangulation technique (LTT) to determine the deformation of the mechanical elements of farm machines. A flat cutting disc with standardized dimension was selected as the object of study, which is commonly used in farm machines, exhibiting simple geometry made of steel, making the analysis procedure easier for experimental execution as well as for data validation. Displacements of 1.0 mm to 10 mm was applied on the specimen. Displacement theoretical behavior of specimen was defined by finite element modelling with same condition of loading and dimension to compare the generated data by the experimental tests. Results indicated a displacement maximum variation of 2.56% between experimental datas and theoretical results and considered satisfactory. LTT was possible to determine deformation curve behavior of machine elements. It was concluded that Laser Triangulation Technique (LTT) to determine the deformation of a specimen proved to be satisfactory
