摘　　要：以加筋壁板应用为背景,研究帽形梁先进拉挤热压装置。提出热压模具长度设计方法,选定了热压模具加压工作方式;以制件成型后各截面厚度一致为原则,给定截面尺寸进行受力分析与有限元验证;优化模具加压点间距,完成加压机构设计;选定预浸料体系,计算所需加热功率,设计加热方案;最后,完成了热压装置研制和帽形梁拉挤试验。With the wider application of the stiffener structure, the hot pressing equipment of advanced pultrusion manufactured hat stiffeners is studied. The length design of the mold is promoted, and the pressing method is chosen. The force analysis of given sectional size and the finite element analysis are performed. The spacing distances between the pressure points are opti- mized, and the design of pressing equipment are complet- ed. The prepreg material system is determined, the heating power is calculated, and the heating scheme is designed. Finally, the research of the equipment is accomplished and the advanced pultrusion process of hat stiffeners is tested.
