  1. This paper starts the research of the liquid floated pendulous accelerometer testing system according to the engineering. at first, this paper gives the brief introduction of the history and present status of accelerometer and its testing technology, the working principium and math model of the liquid floated pendu - lous accelerometer, and then, decides the binary width pulse force retrim loop as the design proposal of testing system, researches the transfer function of every part in the system emphasizly, analyses the stability of the whole accelerometer testing system from the angle of control theoretics by the open loop transfer function of system, and designed the correcting net, analyses the basal problems such as resolution, sampling restraint, precision and so on, designs the hardware testing circuits such as preamplification, band - pass filter, alternating amplifier, phase sensitive demodulatorn, pulse - width modulation, frequency scale circuit, moment current generator. finally, using the graphics program language labv - iew which is designed for testing field especially by ni accomplishes the solfware design of testing system, realized the testing functions

    首先對加速度計及其技術的發展歷史和現狀,液浮擺式加速度計的工作原理和數學模型等作了簡要的介紹,然後確定了以二元調寬脈沖再平衡迴路為設計方案,並從控制理論的角度進行了分析,著重研究了系統中各部分的傳遞函數,利用系統開環傳遞函數分析了系統的穩定性,同時設計了系統的校正網路;分析了二元調寬脈沖再平衡迴路的解析度、采樣約束以及精度等基本問題,並按照系統分析的結果設計了包括前置放大、帶通濾、交流放大、相敏解調、脈寬調制、頻標電路以及力矩電流發生器等系統各部分硬體電路,驗證了電路的正確性,最後按照系統的要求,採用了國ni公司專為領域所開發的虛擬器工具? ? labview作為軟體開發工具,利用該圖形化編程語言完成了系統軟體部分的設計,實現了功能。
