无机支柱真空玻璃的封接边缘受力分析

Force analysis of sealing edge of vacuum glass with inorganic pillars

利用有限元软件对真空玻璃在大气压荷载下的受力进行模拟分析,可以得到详细直观的受力结果,弥补了理论公式难以准确得到真空玻璃受力情况的缺点,更好地为真空玻璃的应用提供理论数据。文章利用ANSYS有限元软件模拟分析了无机支撑柱的真空玻璃,研究封接边缘受力及其对真空玻璃受力的影响。结果表明:真空玻璃受到的压力由支撑柱和封边共同承担,封边区域既有压力也有拉力;封边对第1、2圈支撑柱的影响最大;将位移最大的第2圈支撑柱的弹性模量增大,甚至采用不同于无机支柱的刚性支柱,可以减小真空玻璃在大气压下的最大位移;在变形允许的范围内,真空玻璃的支撑柱的高度可以适当增加。

Using the finite element software to simulate the stress of vacuum glass under the atmospheric pressure load,we can get the detailed and intuitive stress results,make up for the shortcomings of using the theoretical formula to accurately get the stress situation of vacuum glass,and better provide the theoretical data for the application of vacuum glass.In this paper,the finite element software ANSYS is used to simulate and analyze the vacuum glass of the inorganic support column.The results show that the pressure on the vacuum glass is shared by the support column and the sealing edge,and there is both pressure and tension in the sealing edge area;the sealing edge has the greatest influence on the first and second ring of the support column;the elastic modulus of the second ring of the support column with the largest displacement is increased,and even the rigid column different from the inorganic column is adopted,which can reduce the maximum displacement of the vacuum glass under atmospheric pressure;the deformation is allowed Within the allowable range,the height of the support column of the vacuum glass can be increased appropriately.
