Analysis of Pipe System with Passive Vibration Absorber
The Vibration problem is the main cause of pipeline accidents.Passive vibration absorber is widely used in pipeline vibration absorption which has small environmental dependence and high engineering applicability.The free vibration of pipeline system is analyzed by transfer matrix method.The vibration absorber is introduced in the second kind of Lagrange equation.The damping term is introduced into the equation in the form of damping viscous force.The forced vibration of pipeline is analyzed by solving the vibration equation.The correctness of this method is verified by comparing with the finite element method.A three-section pipeline model with vibration absorber is analyzed in this paper.The results show that when a large mass absorber is divided into two small mass absorbers,the effect of vibration absorption will be improved.
