              Abstract:As an important power element,the vibration noise generated by a linear conjugated internal meshing gear pump is one of the key
              problems  to  be  solved  in  hydraulic  systems.  In  this  paper,  the  main  structural  noise  excitation  force  of  the  gear  pump  is  calculated  by
              establishing a lumped parameter model, and its vibration response is studied by establishing a finite element model, and its radiated noise and
              panel sound pressure contribution are analyzed by establishing an acoustic boundary element model. The finite element model of the gear pump
              is verified by experimental modal analysis and vibration experiments, and the acoustic boundary element model is verified by sound source
              localization  experiments.  The  results  show  that  the  established  simulation  model  has  good  accuracy.  The  fundamental  frequency  and  its
              harmonics are the main frequencies affecting the vibration noise of the gear pump. The vibration noise region of the gear pump is identified. The
              maximum  value  of  vibration  speed  is  mainly  concentrated  in  the  pump  rear  cover,  and  the  noise  sound  pressure  value  shows  a  trend  of
              decreasing and then increasing from the inlet side to the outlet side. This paper provides a basis for the structure optimization design of the gear pump.
