Numerical Simulation of the Influence of Gear Modification on the Meshing Stiffness by Wang Zhiqin, Wang Xiaosun, Wang Shiru, Wu Shijing

“…In order to explore the influence of gear modification on the meshing stiffness，two different methods are used to calculate the gear meshing stiffness.First，the gear is parametrically modeled by Pro/E secondary development，and the gear model is imported into Abaqus software for finite element simulation calculation.The time-varying mesh stiffness curve is obtained through data processing.Second is based on the energy method of the analytical method to calculate the time-varying mesh stiffness curve.The results show that within a certain range，the coincidence degree of gear meshing decreases with the increase of gear displacement coefficient and the average meshing stiffness of the gear decreases as the gear displacement coefficient increases.…”

SIMULATION RESEARCH ON GEAR CRACK FAULT BASED ON ADAMS by ZHANG YongXiang, TU Hu, LU Jie, ZHU DanChen, ZHAO Lei

“…In order to study the variation law of gear crack fault vibration signal under different conditions,the gear crack fault was simulated based on the characteristic of flexible body in ADAMS,and the fully flexible gearbox models with different degrees of gear crack fault were established.Crack depth,position of measuring points,input speed and load torque were analyzed on their effects to vibration signal of the gearbox.The results show that the deeper the crack,the closer the position of the measuring point to the crack failure source,the larger the input speed and load torque,the greater the impact and amplitude of the vibration signal,and the amplitude of the vertical acceleration signal is larger than that of the axial acceleration signal.The analysis results of the transmission characteristics of the system show that the transmission law and frequency distribution of the vibration signal are basically consistent with the results of the variation law of vibration signal of different measuring points,and the simulation results are verified by hammering experiments.The research results have a certain reference value for the simulation and experimental research of gear crack fault.…”

“…And on this basis,the fatigue life danger zone was founded based on the dynamic stress recovery method,and fracture simulation was analyzed for the region. The results show that the operating cycles reduced from millions to ten thousand times after fatigue cracks taking place,so once the crack was founded,it was the best time to replace the connecting rod to avoid catastrophic accidents.…”
