《GB/T 11320-1989压电陶瓷材料性能测试方法 低机械品质因数压电陶瓷材料性能的测试》由339-1(工业和信息化部(电子))归口,主管部门为工业和信息化部(电子)。
本标准规定用导纳圆图汉测定低品质因数压电陶瓷振子的厚度振动模的机电耦合系数kt和品质因数Qm。本标准适用于k2tQm不小于0.2的低品质坚固耐用数压电陶瓷材料。
Scope
This standard stipulates that the electromechanical coupling coefficient kt and the quality factor Qm of the thickness vibration mode of piezoelectric ceramic vibrator with low quality factor shall be determined by admittance chart method. This standard is applicable to piezoelectric ceramic materials with low quality factor of kt2Qmnot less than 0.2.
