2万g量程压阻式加速度传感器的非线性研究

在弹体侵彻混凝土的实验过程中,由于压阻式加速度传感器具有零漂、外围电路简单、抗过载能力强等优点,成为高量程微加速度计设计的首选,因此我们采用压阻式加速度传感器,通过采用弹载存储测试技术,记录弹体膛内及侵彻过程中的实时加速度,分析了实测的加速度曲线,膛内及侵彻速度曲线,侵彻深度.发现了加速度传感器非线性问题,在马歇特锤上...

Resrarch about nonlinear of the 2 million g range piezoresistive acceleration

In the process of projectile penetrates concrete experimental process,Due to the piezoresistive accelerometer with zero drift,simple outer circuit,overload capacity.It becomes the first design of high-level micro accelerometer.So we use the piezoresistive acceleration sensor.by using the ammunition stored test technology,we recorded the acceleration during projectile and penetration process,Measured deceleration-time data,and the in and penetration speed curve and the penetration depth were analized.The non...
