Torsional Vibration Analysis and Comprehensive Field Testing on a Large Rotary Kiln

Despite recent advances in maintenance and lubrication technology for large machinery, many gear-driven rotary machines are plagued with heavy wear and recurrent failure. In many cases, these problems are due to torsional vibration. The use of modal analysis and strain gauge measurements to investigate vibration problems is an effective technique which is extensively used in the aerospace, turbomachinery, and automotive fields.
