Abstract
The article presents the possibility to diagnose a machine – physical object – in particular diesel engine. Studies were organized to demonstrate the possibility to use LDV (Laser Doppler Vibrometry) in the fundamental (diagnostic) studies. The object tested is a common model of modern diesel engine, frequently used in currently available vehicles. This paper describes the results of researches performed based on the displacement and the velocity, which indicates usefulness of each of these variables. In addition, the article presents older type of vibration detection system uses in vehicles (based on accelerometers) and conditioning path of the received vibroacoustic signal to become complete and fully useful diagnostic information.
