Study on the Influence of Gear Elastic Deformation on the Dynamic Characteristic of Transmission by He Changran, He Jingliang, He Qu

“…Based on the theory of mechanical dynamics,the influence on dynamic characteristic of transmission is researched when the tooth generated elastic deformation under load.First,in order to build the transmission dynamic analysis model,the stiffness matrix,mass matrix and node positions information of the transmission box are extracted and combined with transmission part virtual assembly.Then,the mesh misalignment,transmission error and tooth contact condition caused by elastic deformation of tooth are calculated.The effect of tooth elastic deformation on meshing quality of gear pair and dynamic characteristic of transmission are analyzed.Finally,according to the theory of elastic-mechanics,the meshing quality is improved through modification of tooth profiles to achieve the purpose of decreasing the dynamic response of gear pair under load.These results provide references for reducing the elastic deformation of tooth effectively and improving the dynamic characteristic of transmission.…”

Locating causes of abnormality of EPG experience based on decision tree by Xiaomin TAN, Ai FANG, Bing LIANG, Haojie YANG

“…Improving user experience has always been the focus of IPTV operation.However,IPTV network is relatively complex,including multiple scheduling links such as set-top box,access network,EPG page,EPG server and media server.Once the abnormality occurs,monitoring indicators of each link will be checked to locate the cause of abnormality by human experience.The operation mode relies on professionals,which is inefficient and unable to stop losses quickly.Thus,to solve the problem above,based on big data technology,decision tree was implied to locate the cause of abnormality according to the classification rule of the tree model.Decision tree model has been used in actual networks of IPTV and helps to find out the cause of abnormality,which improves the efficiency of operation.…”
