Simulation model for the analysis of the kinematics of a forest planter with two rotors

Abstract

About 120 thousand hectares of forest are cut down in our country every year, so it is necessary to carry out artificial reforestation. The level of mechanization of sowing and planting forests is low – 22%, and in order to increase it, it is necessary to develop new and improve existing forest planting machines. The development of structures and mathematical apparatus should be carried out using domestic software. To determine the parameters of the forest planting apparatus, it is necessary to determine the movements of its links. In this work, domestic software was used. A three-dimensional model of parts and assembly of a forest planter was modeled in CAD KOMPAS-3D. A simulation model with geometric parameters obtained from a three-dimensional model was made in the SimInTech dynamic simulation environment. A simulation experiment was carried out in SimInTech, the trajectories of the studied points of the gripping mechanism were determined, taking into account the furrow profile, feed rate and geometrical parameters of the structure. The simulation model also includes a requirement for the quality of the machine, namely, maintaining a zero gripping speed relative to the ground when planting seedlings in the soil. The developed simulation model can be integrated into the control device to adjust the disk rotation speed when the machine feed speed changes, as well as to match the speeds with the seedling feed mechanism.
