复合量程加速度计在炮射导弹中的研究及应用

Research and Application of the Multi-ranged Micro Accelerometer in Artillery Missiles

针对炮射导弹在发射、飞行时的特殊环境,安装多个传感器所产生的测量信号位置误差等问题,设计研究了复合量程微加速度计。对其内部结构及外围的温度补偿电路进行分析。通过仿真得出复合量程微加速度计的外壳结构可以承受20 000 g的冲击,并用实验验证复合量程微加速度计适合测量炮射导弹发射时的冲击测量。在炮射导弹上具有良好的应用价值。

It is designed a multi-ranged micro accelerometer to adapt the special environment of artillery mis- siles when launch and flight, and try to solve the problem that position error of measuring signals caused by instal- ling multiple sensors. Analysed its internal structure and external temperature compensation circuit, simulation show that the shell structure of multi-ranged micro accelerometer can withstand 20 000 g impact. Experiment veri- fied that the multi-ranged micro accelerometer suitable for measuring the impact of artillery missiles when lunch. It has good application value on artillery missiles.
