The Design And Research Of Windbreak And Sand Fixation StrawCheckerboard Barriers Paving Robot's Cutting Setup

Threatening human-being's survival by desert has been the most serious problem and all the countries are seeking methods to solve windbreak and sand fixation problem. This thesis are finished on the basis of "863" task named as <>. Through the international and national information, also the comparison and analysis of windbreak and sand fixation, it is concluded that sand fixation and falling back can only be solved by combination of sand harness in engineering and sand control with biological measures. Though straw checkerboard is an effective method to stop sand dune, it has low efficiency and costs more manpower and resource by man-made straw infixing. It is thus necessary to develop a high-automatic straw infixing system. Straw checkerboard robot appears to be studied under this condition.Straw checkerboard comprise of power system, portrait straw infixing system and landscape orientated straw infixing system. Among them, landscape orientated straw infixing system is the most difficult part in this project, which contains straw transporting, straw exchanging, cutting, straw infixing, automatic lift and needs high consistency and balance among these systems.Cutting system is regarded as the most important part in landscape orientated pavement system of Checkerboard Barriers Paving Robot's Cutting Setup and it will directly effects the robot's running. This thesis aims at designing a new system which is appropriate for working environment and can take the cutting responsibility for the task and function of Checkerboard Barriers Paving Robot's Cutting Setup. In this thesis, computer emulating technology is mainly applied. By the direct three-dimensional model by Pro/Engineer software, we can get more direct impression and observe out whether interference exists or not. Besides, this thesis processes the dynamics emulation of cutting system by ADAMS. By the running of emulation observing system, it draws speed and displacement parameter on main part, so it theoretically assures the feasibility and appropriateness of cutting system. Last, through the access of Pro/Engineer and finite element analyzing system, it gives a model analysis by ANSYS for finite element analysis, parameter analysis of system intensity, distortion after force and equal stress. Thus it presents you the optimizing design for unappropriate system and makes the lab analysis on cutting system. It takes three steps to analyze the running effects, practicability, rate of cutting and also the other structure. The result from emulating analysis are also validated and it points out the deficiency and establish corresponding method for assuring system going smoothly.The final results are also fully validated the importance function of emulating software in engine design. It can dramatically save design time and assures design cor(?)etness, and optimization and can provide some valuable suggestion for the popularizing of emulating software in engine design fields.
