Theoretical Study On Dynamic Characteristic Of Ecoplanter

To increase the forest coverage, protect the ecologic environment, control wind and fix shifting sand, we must carry out the tree planting and the forestation. But the missions are very heavy and considerably seasonal, the mechanization must be adopted so as to improve further the productivity, lower the production cost, realize the high-speed forestation with high quality and raise the survival rate of the seedling. The ecoplaner designed in this paper can defend the vegetations in the ground perfectly with low energy consumption, high productivity and high survival rate of the seedling.To begin with, this paper analyzes the general design principle of ecoplaner qualitatively. It introduces with emphasis the choices of the types of each mechanism and offers much information about them in the course of design of the tree planting machine.Subsequently this paper applies linear modification approximation theory-the method of Newton-Raphson to perform kinematics analysis on the hanging system of the scarification mechanism of ecoplaner and discusses the pit shape of ecoplaner. This paper also applies the methods of the Elasto-Dynamic Analysis to divide the multi-linkage mechanism into the finite elements with founding repetitively kinematics differential equation of the several elements and selecting thirty-one generalized coordinates to analyze the dynamics characteristic of the mechanism, founds the differential equation of the system, adopts the method of time discrete and real mode superposition to solve it, and discusses dynamics characteristic of the system.This paper calculates the problems discussed in the paper and carries out the numeral simulation on the problems of pit shape and Elasto-Dynamics with the business software-MAILAB.In addition, this paper uses Pro/ ENGINER to perform the construction assembly ,the motion interfere check and the kinematics analysis for the studying system to validate the kinematics analysis of the system in the preceding text and carries out the Finite Element Analysis(FEA) by use of ANSYS. This makes the designer have more distinct knowledge to the mechanism motion property and structure property of developed product prototype before formal production, and raises the successful rate of product development.
