摘要
根据压电陶瓷晶体压电原理、压电陶瓷棒和试样横振动原理 ,分析了动态杨氏模量实验中出现的多个谐振频率 ,理论分析与实验结果吻合 .
Different resonant frequencies appeared in the determination experiment of dynamic Young modulus are theoretically analyzed based on the piezoelectric effect of piezoelectric ceramic crystal and the transverse vibration of both piezoelectric ceramic cudgel and the specimen. The theoretical analysis is consistent with the experimental results.
