Design And Research Of Small Self-propelled Four Round Saw Bush Cutting Machine

Based on the depth analysis of the development of shrub cutting machine of the history and current situation at home and abroad,as well as the development trend.With the advantages and disadvantages of various kinds of cutting machine be compared,the program of artificial shrub forest tracked self-propelled four-circular cutting machine was designed,it suitable for the development of artificial shrubbery in China.To the growth characteristics and planting environment of shrubbery,in the paper the cutting machine was designed and the crawler walking mechanism as the carrier.Combined with the processing needs and processing technology,and ultimately determine the overall layout of the cutting machine structure,and the cutting machine of the walking mechanism,cutting irrigation institutions,transmission systems and flip adjustment device in-depth study to determine the composition of the various structural components Form,connection and installation dimensions.The performance parameters of the crawler type cutting machine are overall studied,and the theory of shrub cutting is deeply studied.The cutting force and cutting power are calculated according to the cutting elements.On the basis of the calculation of the cutting force and cutting power of the machining spindle,the key components of cutting machine are analyzed by ANSYS finite element analysis software,including static analysis and modal analysis and topological optimization analysis.Stress obtained on the basis of the key components of a static analysis,the strain deformation cloud,the strength and rigidity of key components were tested,in the modal analysis,the data of the low order natural frequency and the mode of the key components are obtained,but also to verify the rationality of structural design of key components,topology optimization was guaranteed under the premise of stiffness and strength,but also it was reduced the quality of the material.Using the MATLAB software to optimize the cutting spindle,and write the optimization program,and set the optimization parameters,and the structural parameters of the optimized spindle are finally obtained,and the original design has been improved and optimized.To improve the design of the brush machine machine performance.Finally for this kind of operation mode,the motion simulation analysis of the flipping mechanism is carried out by using the ADAMS to analyze the kinematic performance of the turning mechanism.
