摘要
对高脚玻璃酒杯杯沿受力F激励后杯壁发生振动的现象进行了研究,利用DIS声传感数字化信息系统采集振动频率,研究频率与振动有效质量之间的关系,结合振动理论研究其杯壁的受迫振动机理.
The vibration and acoustic phenomena of a wineglass excited by a force was investiga‐ted .The relationship between frequency and vibration effective mass was discussed by collecting data of vibration frequency by sound sensitive digital information system （DIS ） . The forced vibration mechanism was analyzed with vibration theory .
