Nowadays, autoclaves are widely used for industrial applications such as composite material production, laminated glass production and rubber industry. An autoclave is pressurized and heated up according to its special recipes, which are prepared by considering the technical specifications of the interlayer material and the types and thickness of the glass sheets. During the entire laminated glass production period, the gasket on the autoclave door provides sealing and it must not damage the steady air circulation inside the autoclave. In the present study, the sealing of a glass lamination autoclave was investigated numerically. In order to perform finite-element analysis (FEA), a simplified finite-element model was created by considering both the gaps between the autoclave door and its housing and the geometry of the gasket. In general, hyper-elasticity-based gasket materials were used for glass laminating autoclaves. A Mooney–Rivlin hyper-elastic material model was used for this study. In this study, nine different gasket geometries were designed and finite-element method (FEM) analyses of the gaskets were carried out by using the Ansys Workbench software. FEM analyses were performed at 13 bar operating pressure. The results were compared in terms of deformation of the gaskets and von Mises equivalent stress. The most suitable gasket geometry was determined according to the simulation and FEA results.

密封玻璃层压高压釜的垫片几何结构分析

如今，高压釜广泛用于复合材料生产、夹层玻璃生产和橡胶工业等工业应用。高压釜根据其特殊配方进行加压和加热，该配方是考虑夹层材料的技术规格以及玻璃板的类型和厚度而制备的。在整个夹层玻璃生产过程中，高压釜门上的垫圈起到密封作用，不得破坏高压釜内稳定的空气循环。在本研究中，对玻璃层压高压釜的密封进行了数值研究。为了进行有限元分析 (FEA)，通过考虑高压釜门与其外壳之间的间隙以及垫圈的几何形状，创建了一个简化的有限元模型。一般来说，基于超弹性的垫片材料用于玻璃层压高压釜。本研究使用 Mooney-Rivlin 超弹性材料模型。在这项研究中，设计了九种不同的垫片几何形状，并使用 Ansys Workbench 软件对垫片进行了有限元法 (FEM) 分析。FEM 分析在 13 巴的操作压力下进行。根据垫圈的变形和冯米塞斯等效应力对结果进行比较。根据模拟和 FEA 结果确定最合适的垫圈几何形状。设计了九种不同的垫片几何形状，并使用 Ansys Workbench 软件对垫片进行了有限元法 (FEM) 分析。FEM 分析在 13 巴的操作压力下进行。根据垫圈的变形和冯米塞斯等效应力对结果进行比较。根据模拟和 FEA 结果确定最合适的垫圈几何形状。设计了九种不同的垫片几何形状，并使用 Ansys Workbench 软件对垫片进行了有限元法 (FEM) 分析。FEM 分析在 13 巴的操作压力下进行。根据垫圈的变形和冯米塞斯等效应力对结果进行比较。根据模拟和 FEA 结果确定最合适的垫圈几何形状。
