【摘要】 钻井液振动筛是现代钻机成套固控设备中必不可少的第一级基本筛分设备，承担了清除钻井液中大部分固相的任务，其工作能力的好坏直接决定了固控系统是否能够很好地完成任务。在新型钻采设备的现代设计工作中，运用现代静、动态测试技术，全面提高产品性能已成为重要研发环节，同时又为设备的维护维修提供了可靠保障。为保证钻井液振动筛的制造质量，国家标准《钻井液振动筛》GB／T11648-89规定每台出厂的钻井液振动筛必须做动态试验，经检测合格方可出厂。运用现代科学和仪器技术提高振动筛动态测试的水平和可靠性，将智能控件化虚拟仪器这一全新的概念引入到钻井振动筛动态特性检测中，依照振动筛检测国家标准，开发研制振动筛动态特性检测仪势在必行。 论文简介了测试仪器的发展历程，即从传统的硬件化仪器经虚拟仪器到今天的智能控件化虚拟仪器。分析了智能控件化虚拟仪器的特点，并与以往传统的硬件化仪器和现在的LabVIEW等图形化仪器编程语言做了比较。还从功能赋予、测试融合和虚拟仪器的积木式拼搭三部分介绍了智能控件化虚拟仪器的基本概念、设计思想，从非智能虚拟控件的模型要素到智能虚拟控件的形成过程，最后介绍了框架协议集成开发系统和智能控件化虚拟仪器的形成过程，论述了智能控件化虚拟仪器的形成原理。 论文对振动筛动态特性检测仪的现状，振动筛动态特性及检测分析、信号处理方法等都做了详尽的研究，包括振动信号的时域分析、频域分析、幅值域分析及关于振动筛动态特性检测功能分析等，完成了智能控件化振动筛动态特性检测仪的功能建模和这些功能的程序设计，并提供了相应的功能接口函数。 在VMIDS开发系统中拼搭组装出了可供工程实际应用的智能控件化振动筛动态特性检测仪。从振动筛动态特性检测仪的硬件组成、结构和系统软件开发环境两方面，对振动筛动态特性检测仪进行了总体设计。简要介绍了VMIDS开发系统的组成要素，并结合振动筛这一具体对象的动态特性检测，进行了功能库的建模和程序设计，从控件的创建，属性修改，功能赋予等步骤拼搭出完整的、可供工程实际应用的智能控件化振动筛动态特性检测仪，并给出了智能控件化振动筛动态特性检测仪的实验验证。工程实践表明，智能控件化振动筛动态特性检测仪具有功能强、精度高、成本低、开放性和扩展性好等优点，在一定程度上可替代相应的硬件化仪器，具有很好的应用前景。更多还原

【Abstract】 The Shale shaker is the first essential equipment of the modern drilling solid-control machines, which undertakes most work of weeding out solids in the drilling liquid, the capability of which directly result in whether the solid control systems can fulfill the work well. Using static and dynamic measurements are the important develop steps in newly design of drilling machines in order to fully improvement the product quality, To ensure the manufacture quality of Shale shaker, the Shale shaker GB/T11648-89 stipulates that every Shale shaker must be done dynamic experiment and measurement before leave factory. The dynamic measurement on Shale shaker is the indispensable and important means to product inspections, which provides the guarantee to maintain equipments. To upgrade the reliability and the level of dynamic measurement on Shale shaker, develop the instrument of dynamic measurement on Shale shaker, using modern science and instrument technology, is imperative at presentThe paper introduces the development history of test instrument—from traditional hardware instrument to the current visual instrument based on Intelligent Virtual Control via Virtual Instrument. Analyzes the characteristics of the Intelligent Virtual Control and compared with traditional hardware instrument and LabVIEW—graphical programming language. The paper also Introduces the basic concept and design principle of virtual instrument based on Intelligent Virtual Control in three aspects, function endowing, test fusing and assembling as building blocks, the forming process from model elements of non-intelligent virtual control to Intelligent Virtual Control. At last, the paper introduces the forming process of virtual instruments based on Intelligent Virtual Control in frame agreement integrated develop system, and the principle of forming virtual instrument based on intelligent virtual controls.The paper elaborates the status of Shale shaker dynamic measurements, the basic dynamic characters and the measure mechanism of Shale shaker, signal processing, involving vibration signal of time-domain analysis, frequency-domain analysis, amplitude-frequency domain and Shale shaker dynamic measurements functional analysis etc. the paper completes the instrument function model building and programs, providing the corresponding interface functions as well.The Shale shaker dynamic measurement instruments that can be used in Shale shaker dynamic measurement engineering is assembled in VMIDS develop system. The Shale shaker dynamic measurement instrument is designed as a whole both the composition of the hardware and the software develop environment. The paper introduces the constitution elements of VMIDS develop system from assembling field of instruments, function library of instruments and intelligent virtual controls. The paper gives the dynamic measurement function modeling and program designing, according to the dynamic characters of Shale shaker-the specific更多还原
