Abstract Details

2016, MS, University of Cincinnati, Engineering and Applied Science: Mechanical Engineering.
Currently, to obtain an understanding of the frequency and damping of the modes of a rotating system, an impact test or a shaker test is done to find the frequency at which the modes of the system exist. Then, test is conducted under operating conditions to obtain an understanding of the response of the system. A mode enhanced order track (MEOT) can be used to estimate the frequency and damping of various modes directly from the operating data of a rotating system but it cannot find modes which are very close together in frequency or those that are repeated. The MEOT is a method described in a PhD dissertation by Dr. Blough but has not been tested on data obtained from an actual rotating system under operating conditions. The MEOT method was evaluated utilizing data taken from a leaf blower, using a laser tachometer and seven triaxial sensors. Using MEOT, the frequency and damping of different modes was found. These were then compared to the results obtained from an impact test performed on the leaf blower. This MEOT method was also tested after using the virtual sensor concept on the data. A virtual sensor was created for each triaxial sensor. The results obtained from the impact test, the MEOT method and the MEOT method performed on the virtual sensor data were then compared and analysed.
