摘要摘要万方数据万方数据摘要固态散料动态称量装置是一种动态检测设备，在科研、生产和日常经营生活 中起着非常重要的作用。目前，固态散料动态称量所使用的装置有电子皮带秤、 冲板流量计、核子秤和失重秤，但它们均存有缺陷：电子皮带秤需要频繁维修， 冲板流量计接收的信号不够稳定，核子皮带秤测量不够准确，失重秤容易出现物 料堵塞。基于上述问题，新型固态称量装置的试验研究变得很必要。论文在鉴于原有的动态称量装置计量原理和结构模型上，建立了新的力学模 型，利用物理分析，推导出了一种新型动态称量原理，并根据原理进行装置设计。 设计中的机械部分，在结构上采用三段式滑槽相连接，旨在缩短计量时间，避免 物料堵塞，此外，结构中三个传感器进行数据采集，用于稳定信号接收。软件部 分，LabWindows/CVI 编程软件和 Modbus 调试软件的配套使用，给测量的稳定性 提供有效的保障。设计完成，搭建新型称量装置试验台，将汇编的程序导入 CVI 软件中进行试运行，发现初始水平传感器与测量槽之间的顶针连接导致传感器接 收的信号不准确，将其连接方式修改为钢片连接后，很好的解决了这个问题。新 型固态散料动态称量试验台，在经历了不同物料之间、同物料不同状态之间大量 的重复性测量实验后，得到的结果印证了它在使用性能上，较目前使用动态计量 装置具有明显的优势。新型固态散料动态称量装置可以普遍适用于钢厂、煤矿、码头、烟厂等需要 保持连续动态测量的场所，它具有结构简单，造价便宜，测量精度较高，维护量 小等特点，同时还有很大的工程应用价值。关键字：固态散料，动态称量，试验研究，原理设计IABABSTRACTABSTRACTSolid bulk dynamic weighing device is a kind of dynamic testing equipment, in scientific research, production and daily management plays a very important role in the life. At present, the solid powder dynamic weighing used in device of electronic belt scale, impact flow meters, nuclear scale and gravity scale, but they are all flawed: electronic belt scale need frequent repairs, receiving plate flowmeter signal is not stable, nuclear belt scale measurement is not accurate, weightlessness balance materials prone to congestion. Based on the above problems, the experimental research on the new type of solid weighing device become very necessary.Papers in given the original dynamic weighing device on the measuring principle and the structure model, established a new mechanical model, using physical analysis, deduced the principle of a new type of dynamic weighing, and according to the principle of device design.In the design of mechanical parts, connected by three-step chute in the structure, to shorten the measurement time, avoid the material blockage, in addition, three sensors in the structure of the data collection, reception for stability.Software part, LabWindows/CVI programming software and supporting the use of Modbus debugging software, provide effective guarantee f
