Abstract

The article presents an integrated micro self-adaptive sampling acceleration measurement system (IMSAMS) that consists of silicon micromachined or quartz accelerometer, TH9601-ASIC of self-adaptive sampling and encoding, as well as data storage and readout controlling, ADC, RAM, etc. The IMSAMS has been successfully used to measure acceleration information of weapon systems, transportation, health-care, and so on. The main performance parameters include: measurement scale for silicon accelerometer: /spl plusmn/10 g, /spl plusmn/200 g, /spl plusmn/500 g, quartz accelerometer: /spl plusmn/50000 g; real-time self-adaptive sampling frequency f=f/sub 0//spl sim/f/sub 0//n, where f/sub 0//spl les/10 MHz n=1, 2,...,2/sup 14/; memory capacity 512 k bytes; and high g shock in the excess of 60000 g. The composition, operation principle and structure of the IMSAMS are detailed. The test results of the IMSAMS in measuring acceleration waveforms of a separating process of a rocket from a missile by a detonating bolt and a projectile penetrating a concrete target plate are reported.
集成微自适应采样加速度测量系统
本文介绍了一种集成微自适应采样加速度测量系统(IMSAMS),该系统由硅微机械或石英加速度计、自适应采样和编码的TH9601-ASIC、数据存储和读出控制、ADC、RAM等组成。IMSAMS已成功用于武器系统、交通运输、医疗保健等领域的加速度信息测量。主要性能参数包括:硅加速度计的测量刻度:/spl plusmn/ 10g、/spl plusmn/ 200g、/spl plusmn/ 500g、石英加速度计:/spl plusmn/50000 g;实时自适应采样频率f=f/sub 0//spl sim/f/sub 0//n,其中f/sub 0//spl les/ 10mhz n= 1,2,…2 /一口14 /;内存容量512k字节;而高g冲击在60000 g以上。详细介绍了IMSAMS的组成、工作原理和结构。报道了IMSAMS测量火箭弹与导弹在起爆螺栓分离和炮弹侵彻混凝土靶板分离过程中加速度波形的试验结果。
