摘要
基于硫系玻璃材料Ge23Se67Sb10的热机械特性,建立了模压工艺模型,仿真模拟了模压温度、摩擦系数及模压速率对硫系玻璃材料模压成型后等效应力的影响。与L-BAL42材料的模压仿真数据进行对比,讨论了硫系玻璃与传统可见光玻璃在模压工艺上的区别,并优化了模压工艺参数。研究结果表明,随着模压温度的升高、摩擦系数和模压速率的降低,材料模压成型后的等效应力减小。与对照材料相比,硫系材料Ge23Se67Sb10最适合通过改变模压速率来改变等效应力。
Abstract
Based on the thermodynamic properties of chalcogenide glass material Ge23Se67Sb10, the molding process model is established. The effects of molding temperature, friction coefficient and molding rate on the equivalent stress of chalcogenide glass after molding are simulated. Through the comparison with the molding simulation data of L-BAL42 material, the difference between chalcogenide glass and traditional visible light glass in the molding process is discussed, and the parameters of the molding process are optimized. The research results show that the equivalent stress decreases with the increase of molding temperature,the decrease of friction coefficient and molding rate. Compared with the control material, the chalcogenide material Ge23Se67Sb10 is the most suitable for changing the equivalent stress by changing the molding rate.
