Simulation of Fault Condition Vibrations of Mechanical Gearbox

Popis výsledku v původním jazyce

Vehicle's mechanical gearbox is regarded as one of the most crucial elements in a vehicle but it sustains a variety of faults such as broken tooth, misalignment, imbalance, looseness, and even broken case. Using accelerometers, which are mounted on the case for measuring vibration signal, we can detect the faults and monitor the condition but, in the fact, the signals are often complicated and difficult to interpret. Moreover, it is costly and almost impossible to change structure of the mechanical gearbox in order to survey, for instance, dependence of vibration signal on the structure or types of fault. In this paper a dynamic model of mechanical gearbox was developed with tooth breakage to study capability of simulation using software MSC. Adams. The objective of simulation is the mechanical gearbox used on the vehicle that was common combat vehicle in the world. The simulation was analysed based on the nonlinear contact force to predict what happened to the gearbox when occurrence of broken tooth. The contact mechanics model of the meshing teeth is studied by careful calculation and selection of the contact simulation parameters such as the stiffness, force exponent, damping and friction coefficients. To simulate the real working environment of the gearbox, simulated bearings also were built in the MSC. Adams. The paper demonstrated that it is possible to simulate vibration signals by the model of the gearbox created in 3D CAD software and then analysed in multi-body dynamics software MSC. Adams.
