Abstract：The mathematical model of the constrained damping pipe with the function of supporting and vibration reduction is established. The analytical expressions of displacement, dynamic stiffness and loss factor of the damping pipe about the geometric and physical parameters are obtained. The result shows that the length of the damping layer has significant effect on loss factor and there is an optimal length which makes loss factor a max value when the other parameters are given. It provides a quick and convenient optimization method to design a damping pipe.
