Abstract


The fractional Hamiltonian becomes derivation of the finite element method analysis of transmission fluid pipeline unit mass matrix , stiffness matrix and the Coriolis force due to damping matrix . The system equations of motion . The simple pipeline and the main steam pipe . Draw fluid flow rate , fluid pressure , divide the number of cells studied frequencies and mode shapes of the pipeline . The valve is treated as a lumped mass analysis calculated under different steam velocity , vibration frequencies and mode shapes of a steam turbine main steam piping system , given the frequency of the excitation force were the steady-state response of 4Hz, 8Hz, 12Hz The pipeline system . The analysis results are in agreement with field observations .
