基于SolidWorks的甘蔗叶粉碎机刀片分析
|
摘要
用SolidWorks软件建立了甘蔗叶粉碎机的重要工作部件动刀片的三维图,将模型适当进行合理简化,模拟加载动刀片的受力,在合理设置边界条件和载荷并划分高品质的网格后,利用SolidWorks Simulation模块对动刀片进行应力、应变、位移以及优化分析,并对优化后的刀片进行疲劳分析。由此得到了动刀片的合理尺寸,降低了动刀的应力,提高了强度和寿命。
A three dimensional figure of moving blade,which is an important part of Sugar cane leaf shredder is established based on solidworks.The model is simplified properly to simulate the stress of moving blade.After setting the reasonable boundary conditions and loading the high quality of the grid,the stress,strain and displacement and optimization of the moving blade are analyzed using solidworks simulation module and then the fatigue analysis of the optimized blade.As a result,the reasonable size of the blade is got.The simulation experiment showed that this kind of optimization not only reduces the stress of the moving knife,but also increases the strength and longevity.
