This paper studies the mesh characteristics and vibration responses of a gear system with crack and spalling faults using different modeling methods. These modeling methods for the time-varying mesh stiffness (TVMS) include Yang's method, Tian's method and Liang's method which can not consider the effect of the fillet foundation stiffness, Zhou's method, Wan's method, two methods proposed by Ma and...
Bases on the virtual prototyping technology, a CAX integrated analysis environment in the PC platform is built. By the CAX, a simulation model of crankshaft system of internal combustion engine is built. The model is then used to analyze the kinematics and dynamics characteristics of some type crankshaft system. Through comparing the data of simulation result with that of classic literature, the virtual...
Complete contact is often used in assembling wheel hub and shaft which are used in closed impeller assembly of the large turbine compressor. The interference is usually fixed. Because the contact area between wheel and axle is too much, bending shaft is occurred sometimes in assembling and completion of assembling. In order to research the mechanism of bending shaft, based on the nonlinear contact...
