【Abstract】 The influence of the material characteristic parameters and the load on the performance of the gear system is studied.With probabilistic finite element method(PFEM),the gear system is analyzed.The finite element model is verified compared the result of FEM with that of Hertz theory.Moreover,compared the calculated results with different PFEM methods(the response surface method and Monte Carlo method),the response surface method is more efficient than Monte Carlo method for the analysis of the gear system.By using the response surface method,the reliability of the gear system can be efficiently studied.更多还原
