摘要/Abstract

摘要： 提出了评价压电陶瓷激振信号的线性度指标，并基于自主研发的压电陶瓷激励反馈系统，对一款PZT陶瓷进行了实验研究.在分析其激振力的影响因素及影响规律的基础上，提出了压电陶瓷定频激振能力的评价方法.由实验数据建立了评价方程，得到了其定频激振的频率置信区间，使其可以更好地被应用到板壳类薄壁构件的高阶振动测试研究中.研究结果表明，压电陶瓷定频激振能力的总体特点是在低频状态下可实现高幅定频激励，而高频状态下仅能实现低幅定频激励.

关键词: 压电陶瓷激振器, 定频激振, 评价方法, 激振能力, 线性度

Abstract: The linearity index was proposed for evaluating piezoelectric ceramic excitation signal， and experiment was carried out to study a PZT ceramics based on self-designed piezoceramic excitation feedback system. After analyzing the influence factors and law of excitation force， an evaluation method of single-frequency excitation capability was proposed. Evaluation equation was established based on the experimental data， and confidence interval in frequency domain of single-frequency excitation was obtained to make good use of piezoelectric ceramic exciter during the high order vibration test of thin-walled structures. The overall characteristics of the piezoelectric ceramic single-frequency excitation showed that high level excitation capability can be realized under the smaller single-frequency condition， while the low level excitation capability can only be realized under the larger single-frequency condition.

Key words: piezoelectric ceramic exciter, single-frequency excitation, evaluation method；excitation capability, linearity
