Abstract
Dynamic analysis of gearboxes especially driven at high speeds has always been an area of interest for researchers. It is important to know the dynamic behaviour of a gearbox to operate it more efficiently from the friction and vibration point of views. This is important for the automotive industry. To evaluate the vibration of gearboxes produced by a military factory based in Tuzla, an accelerometer is used together with an amplifier and an A/D converter fitted in the computer. Nonrecursive digital filtering programmed by the authors manifested the contribution of vibration from each part of the gearbox.
