【摘要】 在开环压阻式角加速度的基础上,对敏感质量环进行力反馈,提出闭环力平衡系统的设计方案,经试验验证,力平衡压阻式角加速度计具有灵敏度高、阈值小、成本低、抗冲击能力好等优点。由于采用了力反馈技术,使系统响应对于外界干扰和内部系统参数变化不敏感,因此可采用成本较低、要求不高的元件,构成较精密的系统。更多还原

【Abstract】 On the basis of the open-loop piezoresistive angle accelerometer, the design scheme of the closed loopforce balanced system was put forward to proceed the force feedback to sensitive quantity ring. It is approvedthrough experiment that the force balanced angle accelerometer features high sensitivity, small threshold, lowcost and high shock capability. Because adopting the force feedback technique, the system less sensitive to theoutside interfere and change of the internal system parameter. So the more rigid apparatus can be gained by usingthe components of low cost and less demand.更多还原
