2 . prepare the self - adaptive damper which consists of piezoelectric ceramic and er fluids . the experiment show that the resonant peak of the self - adaptive damper minish more than 30 % compared with the damper whose electrostatic field built by piezoelectric ceramic did not charge up er fluids 结果表明,前者相对于后者,阻尼器共振峰被压抑了60以上,从而证实了压电陶瓷在外压力作用下产生的静电场可以驱动电流变液; 2
The numerical simulations show that the resonant peak of the self - adaptive damper minish more than 60 % compared with the damper whose electrostatic field built by piezoelectric ceramic did not charge up er fluids , then which proves that electrostatic field built by piezoelectric ceramic can drive er 通过以上研究,得出了如下结果: 1从理论上模拟了压电陶瓷产生的静电场加在电流变液上和不加在电流变液上两种状态下,阻尼器的振动行为。
