The relationship between semi-active particle damping loss factor and response signal was derived by steady-state energy flow method

and semi-active particle damping loss factor was identified through experimental method. The internal and external features affecting semi-active particle damping loss factor were explored by changing particle filling rate and voltage. The experimental results showed that the semi-active particle damping loss factor can increase by increasing the voltage

and gradually become stable after reaching a certain voltage; in addition

the semi-active particle damping loss factor could increase through increasing particle filling rate. After reaching 70% particle filling rate

the loss factor increased slowly and became stable gradually.
