Acoustic coupling effect in the combustion of fuel is the root of causing the combustor liner vibration. When the excitation frequency and the combustor liner structure natural frequency coincides or nearly, the combustor liner will resonate even cause structural damage. In order to regulate natural frequencies of combustor liner structure to avoid the oscillation frequency effectively that under the working condition, combustor liner design must include appropriate research and experimental verification of its vibration characteristics. The effectiveness of the combustor liner vibration design method and the reliability of combustor liner safe operation are verification effectively by vibration analysis and measurement investigation of gas turbine combustor liner. Technical support and follow-up to ensure safe operation of the new combustor liner design can be provided.
