摘　　要：针对可调行距高速水稻插秧机作业行距调节功能要求,设计一种行距调节机构,移动栽植部分支撑臂的位置,可在一定范围内实现插秧行距无级可调。对调节机构的螺旋轴进行了强度分析与模态分析,应用试验设计与序列二次规划法对螺旋轴进行组合优化设计,并利用二次多项式误差分析法对优化结果进行可行性分析,最后通过试验对样机进行性能验证。结果表明：优化后的螺旋轴质量减轻9.94%,且优化结果可行性高,所设计的调节机构调节方便,调节误差在0.07~0.09mm范围内,满足可调行距高速水稻插秧机工作性能要求。In order to meet the requirements of space adjusting for high speed rice transplanter, an adjustment mechanism was designed to moving the supporting arms of planting parts, thus stepless adjustable space could be achieved within a certain range. Strength analysis and modal analysis of screw shaft of adjustment mechanism was conducted, and the screw shaft was combinatorial optimization designed by using DOE and NLPQL methods. In addition, feasibility analysis for optimized results was done by error analysis method and the performance of prototype was tested. The results show that the mass of optimized screw shaft reduced 9.94 percent and the optimization result is highly feasible. The designed adjusting mechanism is convenient to operate and adjusting error is at the range of 0.07mm to 0.09mm, which can satisfy the actual production requirements.
