Progress in the Application of Finite Element Method in Synthetic Diamonds

  • 摘要: 金刚石以其优异的性能广泛应用于国防工程、机械加工、电子科技等领域,其需求量也日益增大。有限元法适用于复杂几何结构和物理问题的模拟分析,由此开辟了有限元法应用于金刚石合成和相应设备优化的新途径。阐述了有限元方法在六面顶压机及金刚石合成腔体工艺方面的应用进展。首先,考虑静力、应力强度、应力分布和形变等影响因素,对铰链梁和工作缸进行模拟分析,运用有限元法对顶锤的作用、破坏机理及新型顶锤设计进行探讨;其次,总结有限元法在金刚石腔体内的温度场、压力场、电学场等研究中的应用进展;最后,对有限元法在金刚石合成中的应用前景进行展望。
