Abstract: Pipelines are usually subjected to external flexural loads transmitted by pumps or compressors. Apart from the service loading, modern inspection technologies are based on the analysis of guided wave propagation due to impact loading. Both impact and harmonic external load yield pipeline vibration. The article presents a system of 8-coupled first-order partial differential equations describing the vibration response of pipelines under external flexural loads is derived. The decoupling of above equations yields a system of 8 fourth-order partial differential equations. An analytical solution is achieved with the aid of integral transforms. Vibration analysis of pipelines subjected to impact and harmonic loads is provided.

Keywords: vibration, pipelines, flexural loading, integral transforms.
