Abstract

Recently, vibration based diagnostics finds itself useful in many branches of the industry. There is a growing demand for its application to different types of machinery, usually subjected to varying rotational speeds and loads. In order to perform proper analysis, it is necessary to measure the speed together with the vibration signal. Since it is impossible to install speed sensors on all types of the machinery, various speed reconstruction methods have been developed recently. The paper compares existing methods for different types of machinery and different variability of operational conditions. It investigates the efficiency of presented methods for limited speed fluctuations (few revolutions per minute) as well as for major speed changes (run-up). Additionally, it compares results obtained for machinery with relatively complex kinematics (wind turbines) and the simple rotor machinery (test rigs, steam turbines).
