摘　　要：分析了压电陶瓷的压电效应在桥梁振动中减小振动的应用,压电效应将振动机械能转化为电能,进行能量转移从而起到减弱振动的作用。由于压电陶瓷的实验研究费用较高,借助计算机建模技术,对4种数学模型进行了分析。结果表明,压电纤维材料阻抗回路(CPRE)具有较好的应用效果,为后期的实验指明研究方向。This paper describes the application of piezoelectricity of piezoelectric ceramics to the vibration reduction of the bridge,which can transfer energy from kinetic energy of vibration to electric energy in order to weaken vibration.But for its high cost of LAB research,in this work,four mathematic modelings of piezoelectric ceramic are made using ANSYS and the best model of the analyzing is CPRE,which lay a good foundation for the further research.
