The Stress Simulation And Reliable Design For The Main Working Parts Of Self-propelled Rotary Cultivator

XingJiang is in the west of China, winter is very long and the weather is very cold.How to provide dwellers vegetable and fruitage is a flinty question.With the development of economy and the promotion of living stander,the model of production of vegetable in greenhouse and protected-land has been popularized all of the countries.Meanwhile,the fruit production is developing fast.How to realize the mechanization in greenhouse and orchard is a very urgent task to us.The miniature implants developed have few types and simple function,so their use isn't popular,facting this problem,we should develop Self-propelled Rotary Cultivator.The paper have the statics stress simulation and dynamics transient anlysis with ANSYS(one of a CAE software). We use sense organ to collection the data of camber and torsional quadrature.Using the linearity comulation principle of Miner and integrate P-S-N curve of the material to calculate tired longevity.At last optimizing diameter of rotary blade axis with MATHCAD to have the lightest mass as well as obtained betake intension.We selected the self-propelled rotary cultivator as our study object.According to the result of the statics stress simulation,we can observe the infirmness angular rigidity position at middle part of the rotary blade axis.Through dynamics transient anlysis we can gain the stress numberical value table alone with the sequence of diverse rotary blades.Contrast the simulation result with the tested result we discover they are kindred.At last ,by reliability anlyse we obtain the fatigue life of the Self-propelled Rotary Cultivator is 3150 hours and reliable degree is 3.5588.
