【摘要】：静电悬浮无容器技术,是一种十分有效的获取金属材料和非金属材料深过冷现象的手段,其在对熔体过冷度的控制上也相对容易,同时可以测量处于过冷阶段熔体的热物理性质,也可对其进行落管、形核触发等一系列操作。静电悬浮无容器实验中测量得到的热物理性质对于材料制备和分析方面具有十分重要的意义。静电悬浮技术的原理是通过电场力的作用使样品克服重力在两极板间悬浮,对悬浮的状态下的样品采用激光对样品进行加热,使材料达到高温熔化。在静电悬浮实验过程中采集悬浮样品在加热及熔化阶段的图像信息,振荡信号信息,以及温度信息等,为静电悬浮的数据处理模块提供“原材料”。静电悬浮无容器装置实验数据分析管理平台的研发系统的作用主要是基于web框架实现静电悬浮数据处理的功能,求出实验样品的典型热物理性质。同时,利用“互联网+”的思想为静电悬浮无容器技术的实验数据提供了管理和展示的平台。Web框架为应用系统提供了良好的开发框架,本系统以J2EE架构作为平台使用B/S开发模型,采用多层体系结构、MVC模式进行开发,使用Struts2+Hibernate+Spring作为设计框架来实现静电悬浮系统热物性的数据处理、数据管理以及平台搭建部分。本文利用此平台对Zr,Ti90Al10和Ti50Al50的热物理性质进行了计算,得到了三种样品的体积、密度、热膨胀系数、表面张力、粘度系数和比热的数据结果,同时验证了实验装置的功能和性能指标,表明静电悬浮实验装置具备材料科学研究的实验能力。
[Abstract]:Electrostatic suspension without container technology is a very effective way to obtain the undercooling of metal and non-metallic materials, and it is also relatively easy to control the melt undercooling. At the same time, it can measure the thermo-physical properties of the melt in the supercooled stage, and can also drop the tube. A series of operations such as nucleation trigger and so on. The thermophysical properties measured in the experiment of electrostatic levitation without vessel are very important for the preparation and analysis of materials. The principle of electrostatic levitation technology is through the action of electric field force. Allow the sample to overcome gravity and suspend between the two plates. The samples in suspension state are heated by laser to make the material melt at high temperature. The image information and oscillation signal information of suspension sample in heating and melting stage are collected in the process of electrostatic suspension experiment. And temperature information. Provide "raw materials" for data processing modules in electrostatic suspension. The function of the research and development system of the experimental data analysis and management platform of the electrostatic suspension container-less device is mainly based on the web framework to realize the function of the electrostatic suspension data processing. The typical thermophysical properties of the experimental samples are obtained. Using the idea of "Internet" to provide a management and display platform for the experimental data of electrostatic levitation container free technology. Web framework provides a good development framework for the application system. This system uses the J2EE framework as the platform to use the B / S development model, and uses the multi-tier architecture to develop the MVC model. Struts2 Hibernate Spring is used as the design framework to realize the data processing of the thermal properties of electrostatic suspension system. In the part of data management and platform construction, the thermophysical properties of ZrTi90Al10 and Ti50Al50 were calculated by using this platform, and the volume and density of three kinds of samples were obtained. The data of thermal expansion coefficient, surface tension, viscosity coefficient and specific heat are obtained, and the function and performance index of the experimental device are verified, which indicates that the electrostatic suspension experimental device has the experimental ability of material science research.
