【摘要】 为降低全喂入联合收割机收获水稻后留下的高稻茬对油菜免耕播种的影响,设计了往复式稻茬切割器。通过对该往复式切割器传动机构运动动力学分析,建立了基于MATLAB的该传动机构SMULINK振动模型,借助SMULINK振动模型仿真,得出了曲柄平衡块、三角摆块平衡块的质量及质心位置对机构冲击振动影响的关系。找到了传动机构的冲击振动最小时曲柄平衡块、三角摆块平衡块的质量和其对应质心距离回转中心的位置分别为2.113kg,3.0396kg,0.08m和0.07m。更多还原

【Abstract】 In order to reduce the impact of rape no-tillage sowing which made by the high rice stubble left behind by the full-feed rice combine harvester, reciprocating cutter rice stubble has been designed. with the reciprocating movement transmission dynamics analysis, MATLAB-based transmission of the vibration model SMULINK has been established, in virtue of SMULINK vibration model simulation, which can obtained the Shock and vibration effect of mechanism made by the mass of balance block of brace, balance block of triangular block and the location of mass. At last , when the the Shock and vibration effect of mechanism is minimum, the mass of balance block of brace and balance block of triangular block is 2.113kg, 3.0396kg respectively, and its corresponding centroid position from the rotation center is 0.08m and 0.07m respectively.更多还原
