Data Acquisition and Data Preprocessing in Elastomer Measurement System

精确测定喷油泵校正器的预紧力和校正行程 ,具有重要的理论和现实意义。文中先对一种能够精确测量喷油泵校正器预紧力和校正行程的弹性体测量系统的硬件组成部分做了概述 ,然后较详尽地论述了位移和力信号的采样原理、预处理方法及其在本系统中的具体应用。实践表明 。

Accurately measuring the injection pump corrector’s pretightening force and correction stroke has very important theoretic and practical significance. In this paper, first,the elastomer measurement system is summarized. Then,the data sampling and preprocessing methods of force signal and displacement signal and their use in the system are elaborately narrated.The practice indicates that the system works well because it uses the methods of data acquisition and data pre-treatment.
