The dynamic characteristics of hydraulic pipeline elastic mounting bracket directly affect the vibration and noise characteristics of pipeline system, as well as the strength and fatigue life of the mounting bracket itself. The modeling and simulation method of rubber elastic mounting bracket for hydraulic pipeline is studied by using non-linear finite element analysis method. The validity of this method is proved by an engineering example. At the same time, the analysis results show that the use of flexible rubber mounting bracket in hydraulic pipeline system has a good effect on isolating high-frequency noise, and the exciting forces of higher frequency in pipeline has a significant attenuation when it is transmitted to the base.
