Simulation Analysis of the System Reliability of Cylinder Sine Oscillating Tooth Transmission by Yuan Xinmei, Zeng Yunyun, Zhou Sizhu

“…In view of the problem that the conventional analysis method cannot directly solve reliability problem of the complex cylinder sine oscillating tooth transmission system,a simulation method based on minimal cut sets of fault tree is proposed,which can solves system reliability.According to the structural characteristics of cylinder sine oscillating tooth transmission,the function block diagram of the system is given and the fault tree of the system is built.The minimal cut sets of the fault tree are acquired,and the cumulative failure probability and the probability density are calculated.Different types life distribution function of the system are fitted out.The life distribution function is determined preliminarily based on the principle of minimum residual sum of squared,and the K-S hypothesis testing is carried out for the life distribution function,which ultimately determine life distribution function of cylinder sine oscillating tooth transmission is Weibull distribution.The weak links of cylinder sine oscillating tooth transmission system are determined by analysis of model importance.…”

Dynamic Simulation of Gear Tooth under Two Crack Affecting Lines by Cui Lingli, Zhai Hao, Zhang Feibin

“…For the purpose of investigating the effect of crack affecting lines on the gear tooth vibration response,the energy method is used for meshing stiffness calculation,and the effect of two crack affecting lines on meshing stiffness are compared with each other.The accuracy of solving meshing stiffness under crack curve affecting line is proved by the finite element method.Then a dynamics model of gear tooth is built to compare the different responses of gear system under the two crack affecting lines.The result shows that an intersection will appear in the fault detection indicators under two crack affecting lines when the crack size grows up to the special value and the intersection which is different from previous paper is proved to be right.…”
