摘　　要：以2BYFGJ-4型玉米苗带秸秆还田旋耕施肥播种机机架为主要优化分析对象,通过有限元分析软件ANSYS对其进行静力学分析和模态分析,得出该机机架设计的薄弱环节。根据前几阶模态频率和振型,提出机架的优化方案,并以模态频率为衡量指标对各方案进行比较分析。结果表明:优化后的机架具有更好的动态性能,可为下一轮样机制作提供重要依据。Taking 2 BYFGJ-4 band straw returning rotary tillage fertilizing and maize planter frame as the main optimiza-tion object, the author used the finite element analysis software ANSYS to perform static analysis and modal analysis on the frame, and discovered the weak spots.The author proposed optimization solutions of the frame according to the first few modal frequencies and vibration mode.Taking the modal frequency as indicator the author compared the optimization solutions.As the result, the frame after optimization has better modal performance, which can provide an important sup-port for the next prototype.
