| titleOfInvention | Finite element analysis and coordinate conversion method for connecting rod of paddy field grader |
| abstract | The invention relates to a finite element analysis and coordinate transformation method of a connecting rod of a paddy field grader, wherein a land leveling shovel of the grader is regarded as an integral mass block; selecting three parallel connecting rods connected with a land scraper and a vehicle body as research objects, and regarding the research objects as flexible rods; selecting one of the two lower parallel rods for finite element analysis, listing a rigidity matrix and a stress matrix of the connecting rod, and solving the axial deformation of the connecting rod; selecting a connecting rod connected with a hydraulic push rod as a research object, and taking the connecting rod as a bending beam unit for finite element analysis to obtain a rigidity matrix, a displacement matrix and a stress matrix; and finally, transforming the deformed parameters from the local coordinate system to the global coordinate system for representation through coordinate transformation. The invention can conveniently and effectively calculate the deformation conditions of the three connecting rods, provides theoretical reference for finite element modeling in the field of paddy field land levelers of flexible multi-body systems, and belongs to the field of farmland construction machinery. |
