Abstract

A static modeling method and system for a paddy field grader are disclosed. The method comprises the following steps: establishing a three-dimensional solid model of a paddy field grader, replacing atractor body with a bench and fixing the bench, taking the symmetry plane of the paddy field grader as a basic plane, regarding the leveling system as a mass block, establishing a local coordinate system on the mounting table of the mass block, and obtaining the coordinates of the mass center under the local coordinate system; obtaining the force exerted on the mass by the parallel connecting rod,wherein the parallel connecting rod comprises a flexible rod and a rigid rod; establishing a local coordinate system at the end of the flexible rod far away from the mass, obtaining the acting forceand additional force couple of the flexible rod, and also obtaining the deflection and rotation angle of the connecting end of the flexible rod and the mass; obtaining the axial deformation of the rigid bar by tension and compression analysis, and obtaining the deformation position of the connecting end of the parallel connecting rod and the mass block. The invention provides a reference and a basis for fatigue strength checking and dynamic analysis of related parts of a paddy field grader.

Description

technical field [0001] The invention relates to a modeling method, in particular to a static modeling method and system for a paddy field grader, belonging to the field of agricultural machinery. Background technique [0002] During the working process of the paddy field grader, the parallel connecting rod is an important part connecting the tractor body and the leveling system of the grader. Its stiffness and strength determine whether the leveling system can work normally. In the past, the strength analysis was calculated directly with the help of software, lacking the basic static analysis as a theoretical basis. [0003] The dynamic modeling of the leveling system of the grader is inseparable from the design of the model design and control system of different types of graders. Since the middle of the last century, foreign scholars have begun to study the use of paddy field graders (FlorianDiekmann, 2010). In recent years, domestic research on paddy field graders has mai...
