Abstract

In recent years, the vibration problems associated with turbine blades have become of increasing importance. Blades in a gas turbine can fail if they are subjected to alternating forces having certain frequencies. Thus a need has arisen for accurate determination of these dangerous frequencies, so that the possibility of failure occurring during running can be avoided.

This thesis presents a numerical method to predict the frequencies which must be avoided in the design of gas turbines. The accuracy of the method is tested by using it to solve some vibration problems for which analytical or experimental results are available.
