【摘要】：冰雪的融化,巷道工程中的底鼓、坍塌,金属的熔化以及糖类、巧克力等的溶化与我们的日常生活息息相关,这使得研究材料固流转化的理论具有重要的意义和应用价值。本文从冰水固流转化、类软岩流变、聚合物流变以及金属熔化等方面阐述了材料固流转化的过程。本文采用坩埚电阻炉对金属铝进行了熔化实验研究,观察金属铝在固流转化过程中的现象。实验采用相同形状铝块保持相同加热速率的条件下,通过电阻炉加热升温,在升温到铝的熔点左右的温度时,观察铝块状态记录数据。然后研究了不同温度下金属铝块的熔化时间与熔化速率,实验结果表明当金属铝达到熔点后温度越高,金属铝的熔化时间越短,熔化速率越快。然后选用Excel软件对金属铝块的熔化时间及融化速率的影响规律进行了拟合研究,选用ANSYS软件对金属铝固流转化试验结果进行模拟分析,得出它们的熔化规律,且结果显示,模拟过程跟实际试验过程基本相吻合,这亦对试验结论进行了验证。最后,将金属铝固流转化与类软岩流变及冰水固流转化进行了对比分析,通过各自的实验过程、影响因素、模拟分析等方面进行对比,为今后形成一套确切的、普遍适用的理论体系奠定基础。
[Abstract]:The melting of ice and snow, the floor bulge and collapse in roadway engineering, the melting of metal and the melting of sugar and chocolate are closely related to our daily life, which makes the theory of solid flow transformation of materials have important significance and application value. In this paper, the process of solid flow transformation of materials is described from the aspects of frozen water solid flow transformation, soft rock like rheology, polymer rheology and metal melting. In this paper, the melting experiment of aluminum metal was carried out in a crucible resistance furnace, and the phenomenon of metal aluminum in the process of solid flow transformation was observed. Under the condition of the same shape aluminum block keeping the same heating rate and heating temperature through resistance furnace, the state record data of aluminum block are observed when the temperature is about the melting point of aluminum. Then the melting time and melting rate of the metal aluminum at different temperatures are studied. The experimental results show that the higher the temperature is, the shorter the melting time is and the faster the melting rate is. Then, the influence of melting time and melting rate on the melting time and melting rate of aluminum was simulated by using Excel software. The results of solid flow conversion test of aluminum were simulated by ANSYS software, and their melting rules were obtained, and the results showed that, The simulation process is basically consistent with the actual test process, which also verifies the experimental results. Finally, the solid flow transformation of metal aluminum is compared with that of soft rock like rheology and ice water solid flow transformation. Through the experiment process, influence factors, simulation analysis and so on, a set of exact set is formed in the future. A universally applicable theoretical system lays the foundation.
