Simulation Analysis on Strength of Bucket Tooth with Various Soil

摘要：

　　This paper applies large-scale finite element software ANSYS and the module of LS-DYNA to establish the solid model of bucket teeth,and according to Smoothed Particle Hydrodynamics Method (SPH) establishes the soil constitutive model.Emulating the process that bucket teeth excavate soil of three different grade ruggedness coefficients obtains the stress and statistical value of bucket tooth point; Simulation results show that:the stress concentration of bucket teeth point is more serious.When the ruggedness coefficient is0.6<f< 1.0,the corresponding maximum stress is 197 ~ 309MPa,which meets the strength requirement.The damage is caused by the fatigue failure.
