摘要
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,在马歇特锤上对传感器进行了不同冲击加速度下的重新校准后,对弹体在膛内和侵彻混凝土分开来进行计算,从而保证了测试数据的准确性。
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 nonlinear of acceleration sensor problem was found.Thus,we calibrated the acceleration sensor under different impact,so as to ensure the higher accuracy.
