%X 钢化真空玻璃在其两侧温度不同时会发生热变形，该变形可能会导致其发生破碎或是使支撑物的状态发生变化，进而改变钢化真空玻璃的受力情况，最终使其失效。通过理论分析，研究了钢化真空玻璃在温差环境中影响其变形的因素。使用ANSYS模拟钢化真空玻璃在温差环境中发生的变形，从仿真结果中可以看出，在较大温差作用下钢化真空玻璃的变形量不大于失效极限值。为了研究支撑物在钢化真空玻璃发生变形的情况下其状态是否满足其力学特性要求，取钢化真空玻璃样品对其进行冷热循环试验，并于实验结束后对样品中间部位和边缘部位的支撑物进行观察，从试验中可以看出，支撑物的形状及其轴向位移和横向位移均未发生明显变化，同时，支撑物与玻璃紧密接触位置没有对玻璃板造成明显的挤压变形，满足其力学特性要求。<br />
Due to the different temperatures on both sides of the tempered vacuum glass, thermal defor-mation will occur, which may lead to its breakage or change the state of the pillar, and then change the stress condition of the tempered vacuum glass, and finally make it invalid. Through theoretical analysis, this paper studies the factors affecting the deformation of tempered vacuum glass in tem-perature difference environment. ANSYS is used to simulate the deformation of tempered vacuum glass in the temperature difference environment. From the simulation results, it can be seen that under the action of a large temperature difference, the deformation of tempered vacuum glass is not greater than the failure limit value. In order to study whether the state of the pillar meets the requirements of mechanical properties when the tempered vacuum glass is deformed, take the tempered vacuum glass sample for cold and hot cycle test, and observe the pillar at the middle and edge of the sample after the experiment. From the test, it can be seen that the shape of the pillar and its axial displacement and transverse displacement have not changed significantly. At the same time, the close contact position between the pillar and the glass does not cause obvious extrusion deformation to the glass plate, which meets the requirements of its mechanical properties.
