Abstract:
A circular particle damper attached to the turbopump of the liquid rocket engine is designed．The models of the turbopump with and without the particle damper ale built with finite el— ement method to evaluate the damping effect on the vibration of the turbopump．In the simulation， the equivalent structural damping ratio is used to describe the damping performance of the particle damper．Numerical results show that the particle damper can reduce the vibration of the turbopump significantly，and has less effect on the dynamic characteristics of the turbopump．
