摘 要
由于企業(yè)中旋轉(zhuǎn)機(jī)械分布的分散性，及旋轉(zhuǎn)機(jī)械故障的大量存在，特別是旋轉(zhuǎn)機(jī)械中的不平衡故障的大量存在，對旋轉(zhuǎn)機(jī)械的動(dòng)平衡要求越來越大。在此背景下，本文針對性的進(jìn)行了對旋轉(zhuǎn)機(jī)械的動(dòng)平衡系統(tǒng)的簡單設(shè)計(jì)。
本文以常見的旋轉(zhuǎn)機(jī)械的設(shè)備故障為背景，分析了轉(zhuǎn)子故障的存在原因，在設(shè)備振動(dòng)監(jiān)測與故障診斷知識的基礎(chǔ)上，設(shè)計(jì)合理的網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)，以Visual C++6.0軟件、SQL Server數(shù)據(jù)庫為平臺(tái)，針對轉(zhuǎn)子的故障設(shè)計(jì)出了具有針對性的動(dòng)平衡系統(tǒng)。
本文主要研究內(nèi)容如下：
（1）不平衡的產(chǎn)生及其測試方法。分析不平衡引起的振動(dòng)特點(diǎn)，為動(dòng)平衡測試中“測什么？”指明方向，然后研究不平衡轉(zhuǎn)子的平衡校正方法，并對其進(jìn)行動(dòng)平衡處理。
（2）動(dòng)平衡測試系統(tǒng)硬件設(shè)計(jì)。測試系統(tǒng)信號處理中用到的信號需要測試系統(tǒng)硬件提供，分析測試系統(tǒng)硬件組成，然后研究動(dòng)平衡中常用傳感器的特點(diǎn)，對 A/D卡進(jìn)行選擇并進(jìn)行過程設(shè)計(jì)。

ABSTRACT

As rotating machinery enterprises in the distribution of dispersion, and the rotation and there are a lot of mechanical failure, particularly the imbalance in the rotating machinery and there are a lot of faults, the balance of rotating machinery demand is increasing. In this context, the paper focused on a rotating machinery of the balance system of simple design.
Based on the common rotating machinery equipment failure as the background, analysis of the reasons for the existence of rotor failure, equipment vibration monitoring and fault diagnosis on the basis of knowledge, rational design of the network topology, Visual C++6.0 software, SQL Server Database as a platform, for the failure of rotor design a targeted balance system.
Main research content in this paper is as follows:
(1) imbalance in the production and testing methods. Analysis of imbalances caused by vibration characteristics, for balancing test "Measuring What "specified direction, and then on the balance of the rotor imbalance correction method, and its handling balance.
(2) balancing test system hardware design. Test signal processing systems used in the testing system needed to provide hardware, systems analysis and testing of hardware components, and then balance on the characteristics of sensors used in the A/D cards to choose and design process.
(3) The system uses a SQL Server database technology, information systems, equipment, sampling data for the effective management of our various ways of collecting data using a unified format and make full use of a relational database and restraint mechanisms, to the data consistency and integrity.
(4) Application of Visual C++6.0 simple software programming network equipment management system of inspection procedures, the initial inspection of the network management system for inspection data management, analysis and diagnosis of function.
