摘　　要：利用三维加速度测量的特点,研制了一种新型压电式三维加速度传感器。该传感器基于压电式,采用严格圆球型的惯性质量块和严格对称的压电陶瓷片,从而实现了三维加速度的测量。初步的实验结果表明:该传感器性能稳定,3个方向上灵敏度可达到3.0×10-3V.m/s2,其体积小、测量精度高、价格较低、灵活可靠,有重要的应用价值。Based on the characteristics of the Triaxial Accelerometer test, a new Triaxial Piezoelectric Accelerometer has been designed. The accelerometer based on piezoelectric effect, used a strict rotary inertial mass and highly symmetric piezoelectric ceramic pieces. The experimental result shows that the acceleromete has stable performance stabilize and the sensitivities of the three axes are up to 3.0 × 10^-3 V · m/s^2. The accelerometer has the merits of small size, high accuracy of measurement, low price and flexibility. We can see the accelerometer will promising applications.
