【摘要】：滚动轴承是旋转机械中使用最广泛的基础零部件之一,其失效也是导致机械装备非正常停机的最主要故障源之一。建立一个行之有效的试验平台来研究滚动轴承在不同工况条件下的使用性能,为滚动轴承在设计以及使用过程中提供有效建议是及其必要的。而试验平台的建立需要配套其相应的测控系统才能有效和充分发挥试验平台的性能,同时滚动轴承平台的数据管理系统是测控系统当中非常重要的一部分,因此本文从滚动轴承测试平台测控系统的实际需求出发实现平台历史数据的管理,为后续的理论分析和进一步试验研究提供扎实的基础。论文首先系统介绍了研究滚动轴承数据管理系统的必要性,国内外研究现状,引出本文的主要研究目标;随后根据研究目标进行需求分析与功能实现,主要包括:(1)基于LabVIEW软件进行软件编写,采用了生产者/消费者模式的程序框架;(2)采用Access数据库,数据存储采用了TDMS文件格式;(3)实现了用户管理系统、大数据存储、历史数据查询、历史数据导出等功能;最后进行相关试验,进行软件功能的验证。验证结果表明,该系统占用内存和CPU都较少;生产者/消费者模式能避免造成试验过程因数据累积而导致的数据溢出;TDMS文件能及时处理较大数据量,且使用方便;Access数据库使用简单,符合要求。滚动轴承数据管理系统整体软件功能完成度非常好,且各功能环节采用最简单的方式完成相对较大的数据处理工作,完全符合开发需求,可为后续的滚动轴承相关试验提供可靠的数据安全保证。
[Abstract]:Rolling bearing is one of the most widely used basic parts in rotating machinery, and its failure is also one of the main fault sources leading to abnormal shutdown of machinery and equipment. It is necessary to establish an effective test platform to study the performance of rolling bearings under different working conditions, and provide effective advice for the design and operation of rolling bearings. The establishment of the test platform needs its corresponding measurement and control system to effectively and fully display the performance of the test platform. At the same time, the data management system of the rolling bearing platform is a very important part of the measurement and control system. Therefore, based on the actual demand of the measuring and controlling system of the rolling bearing test platform, this paper realizes the management of the historical data of the platform, and provides a solid foundation for the subsequent theoretical analysis and further experimental research. Firstly, the paper introduces the necessity of the research on the rolling bearing data management system, the present situation of the research at home and abroad, and leads to the main research objectives of this paper, and then carries on the requirement analysis and the function realization according to the research goal. The main contents are as follows: (1) based on LabVIEW software, the program framework of producer / consumer model is adopted; (2) Access database and data storage are used in TDMS file format; (3) user management system and big data storage are implemented. Historical data query, historical data export and other functions; finally, related experiments, software function verification. The verification results show that the system occupies less memory and CPU, and the producer / consumer model can avoid the data overflow caused by the data accumulation in the experiment process, and the TDMS file can deal with the large amount of data in time. And easy to use access database is simple to use, in line with the requirements. The whole software of the rolling bearing data management system has a very good degree of function completion, and each function link uses the simplest way to complete the relatively large data processing work, which fully meets the needs of the development. It can provide reliable data safety guarantee for subsequent rolling bearing related test.
