基于稳态能量流法识别半主动颗粒阻尼损耗因子的实验

通过稳态能量流法推导了半主动颗粒阻尼损耗因子与响应的关系,采用实验方法识别了半主动颗粒阻尼的损耗因子。分别研究了颗粒填充率和通电电压对半主动颗粒阻尼损耗因子的影响规律。研究结果表明:增大通电电压能提高半主动颗粒阻尼的损耗因子,损耗因子在到达一定电压后逐渐趋于稳定;半主动颗粒阻尼的损耗因子随着颗粒填充率的增加而增大,但颗粒填充率在达到70%以后,半主动颗粒阻尼的损耗因子增幅变缓并逐渐趋于稳定。

Experiment of identifying semi-active particle damping loss factor based on steady-state energy flow method

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.
