Reliability Analysis of Fatigue Strength of Interceptor Teeth of Coal Mining Machine under Multiple Working Conditions
By proposing the fatigue strength reliability analysis of coal mining machine interceptor teeth impact of cutting resistance and traction and other complex stresses under different working conditions was understood,based on the results of the force analysis,the establishment of the interceptor fatigue strength reliability model,solving the parameters in the model,the parameters of the stress distribution of the interceptor teeth,the parameters of the strength distribution,and substituting them into the fatigue strength reliability model for the calculation.The results show that the design method can significantly improve the fatigue strength reliability of the trunnion and reduce the risk of fatigue damage.
