【摘要】：靜電懸浮無容器技術(shù),是一種十分有效的獲取金屬材料和非金屬材料深過冷現(xiàn)象的手段,其在對熔體過冷度的控制上也相對容易,同時可以測量處于過冷階段熔體的熱物理性質(zhì),也可對其進(jìn)行落管、形核觸發(fā)等一系列操作。靜電懸浮無容器實驗中測量得到的熱物理性質(zhì)對于材料制備和分析方面具有十分重要的意義。靜電懸浮技術(shù)的原理是通過電場力的作用使樣品克服重力在兩極板間懸浮,對懸浮的狀態(tài)下的樣品采用激光對樣品進(jìn)行加熱,使材料達(dá)到高溫熔化。在靜電懸浮實驗過程中采集懸浮樣品在加熱及熔化階段的圖像信息,振蕩信號信息,以及溫度信息等,為靜電懸浮的數(shù)據(jù)處理模塊提供“原材料”。靜電懸浮無容器裝置實驗數(shù)據(jù)分析管理平臺的研發(fā)系統(tǒng)的作用主要是基于web框架實現(xiàn)靜電懸浮數(shù)據(jù)處理的功能,求出實驗樣品的典型熱物理性質(zhì)。同時,利用“互聯(lián)網(wǎng)+”的思想為靜電懸浮無容器技術(shù)的實驗數(shù)據(jù)提供了管理和展示的平臺。Web框架為應(yīng)用系統(tǒng)提供了良好的開發(fā)框架,本系統(tǒng)以J2EE架構(gòu)作為平臺使用B/S開發(fā)模型,采用多層體系結(jié)構(gòu)、MVC模式進(jìn)行開發(fā),使用Struts2+Hibernate+Spring作為設(shè)計框架來實現(xiàn)靜電懸浮系統(tǒng)熱物性的數(shù)據(jù)處理、數(shù)據(jù)管理以及平臺搭建部分。本文利用此平臺對Zr,Ti90Al10和Ti50Al50的熱物理性質(zhì)進(jìn)行了計算,得到了三種樣品的體積、密度、熱膨脹系數(shù)、表面張力、粘度系數(shù)和比熱的數(shù)據(jù)結(jié)果,同時驗證了實驗裝置的功能和性能指標(biāo),表明靜電懸浮實驗裝置具備材料科學(xué)研究的實驗?zāi)芰Α?br/>[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.
