摘要
旋耕弯刀是微型旋耕机的主要工作部件,为保证其在承受外载荷时不发生残余变形和过量的弹性变形,应提高旋耕弯刀强度计算的精确度。采用美国ANSYS软件,给出了旋耕弯刀应力计算的有限元力学模型,计算出所选关键点的应力大小及旋耕弯刀的应力分布规律,得出了应力集中的位置,同时也提高了产品的设计可靠性,降低了产品的原材消耗。
With the rapid technology development,using the advanced design method to device agriculture machine is an urgent affair.FEM——Finite Element Method is the most effective means for numerical value,so it is applied widely at engineering design.The rotary blade is the main work parts of the self-propelled rotary cultivator.Traditional design lacks exact intensity account methods,so having great lessons and blindness.To ensure the rotary blade nonoccurrence remnants transfiguration and superfluous elastical tra...
