摘要
本文研究了一种蒙皮+舵芯结构复合材料空气舵的RTM成型模具方案。通过产品结构分析,确定了组装式的模具主体设计方案,进行了定位机构和合模缝结构设计,有效地解决了舵芯定位和织物缝合的问题;同时采用有限元分析方法对空气舵灌注过程进行仿真分析,对注胶口和出胶口进行了设计优化,采用舵面注射方式时,根据计算结果结合实际情况,适当设置出胶口,可避免缺胶或浸润不良的现象。进行了复合材料空气舵产品试制工作,成型产品外形尺寸较好。通过以上研究,形成了模具设计方案,并根据实际情况对模具进行了有效的优化设计,解决了复合材料空气舵的制作难题,实现了产品的一体成型。
This paper studied a mould project,and the mould was made to manufacture a composite air rudder by RTM process.The air rudder was prepared with a skin/rudder core structure,for which the skin was composite,and the rudder core was metal.By analyze the air rudder,the mould was designed to be a fission mould.To solve those problems such as how to position the air rudder core with the skin and mould-assembling mechanism,a new RTM mould has been designed in the paper,which contains optimized location mechanism and mould-assembling mechanism.Then,modal analysis was done to obtain the most reasonable injections and outlets.When a injection was set up in the surface of the skin,this mould project can avoid the phenomenon of lack of resin.An air rudder was manufactured with preferbly boundary dimension.By those works,this paper provides a mould project and fulfils the integrated manufacture of the air rudder.
