摘　　要：旋耕机是现代农业中最常用的一种翻耕机械,其工作时旋耕刀轴旋转产生的干扰频率如果和机架的固有频率接近,有发生共振的危险。论文以某型号的三点悬挂横轴式旋耕机的机架为研究对象,利用Creo建立了机架的参数化模型,并在ANSYS Workbench中对机架进行了模态分析,得到了机架前六阶模态的相关数据。分析结果表明旋耕刀轴产生的干扰频率为3.0~3.6 Hz远离于机架的固有频率4.80~5.69Hz,不会发生共振危害;同时为旋耕机的优化设计提供了理论依据。The rotary cultivator is most commonly used in modern agriculture as a tillage machinery.When the rotary tillage knife shaft rotating the interference frequency tell if close to natural frequency and frame, there is a risk of the resonance.The frame based on the three point of some type suspension horizontal rotary tiller as the research object, and made the parametric model by Creo, and a modal analysis of the frame is carried out.in ANSYS Workbench.The analysis results show that the interference frequency is Hz 3.0-3.6, which is far from the natural fre-quency of 4.80-5.69 Hz, and it can not be harmful. Provides a theoretical basis for the subsequent optimization design of rotary cultivator.
