Abstract


In this thesis, for aircraft hydraulic oil the car hydraulic piping vibration analysis , and related piping vibration basic theory study . Vehicle vibration of hydraulic oil mainly due to the vibration caused by mechanical vibration and fluid pulsation . In-depth study which pulsatile flow under HINGED - HINGED boundary conditions of pipeline stability and global bifurcation problems . The negative impact of aircraft ground hydraulic oil truck due to vibration analysis and research progress of the hydraulic piping vibration . Analysis of the vibration of the vehicle , according to aircraft the ground hydraulic oil car the principle and vehicle structure , given some of the effective methods to eliminate mechanical vibration . Export pipeline under pulsatile flow vibration differential equations , differential equations dimensionless , and dimensionless equations discretization order status differential equations . The system has a zero eigenvalue conditions , the normal form derivation method of application gyro system through a series of transformations 0:1 internal resonance bifurcation equation , then after re - measure to get a four-dimensional approximation of integrable Hami Dayton system . According to the modal resonance , the global bifurcation energy - phase criteria , as well as fiber bundle theory , the the orbit of Silnikov Hamiltonian resonance case the existence , been a kind of necessary the system exists Silnikov track conditions .
