摘要
飞机进气道采用基于自动铺丝工艺的复合材料整体成型方案,为分析进气道型面自动铺丝的可行性,对进气道型面与铺丝头的干涉问题进行了研究。首先,以进气道型面网格化的STL文件为对象,并结合铺丝头的边界条件,开发了基于VC++6.0的干涉检测计算程序,获得了型面上干涉区域的位置,并以点云进行标识。然后,在CATIA下对标识的干涉区域进行铺丝头外形轮廓的建模,并在Vericut仿真软件下对进气道型面进行自动铺丝运动仿真,验证了型面上标识的干涉区域的正确性。最后,将标识过干涉区域的进气道型面反馈给设计进行型面修正,获得了满足自动铺丝条件的进气道型面。
A composite material integral molding scheme based on the automatic fiber placement process was adopted for the inlet of aircraft.To ensure the feasibility of automatic fiber placement on the molded surface of the inlet,the interference problem between the inlet profile and the fiber laying head was studied.First,a interference detection computing program based on VC++6.0 was developed based on the meshed STL file of the inlet profile together with the boundary conditions of the wire laying head,and the position of the interference area on the molded surface was obtained and marked with large quantities of points.Then,the contour of the fiber laying head was modeled for the identified interference area with CATIA.Subsequently,the kinematic simulation of automatic fiber placement on the molded surface was carried out with VERICUT simulation software for verification purpose.Finally,the molded surface of the inlet identifying the interference area was fed back for design correction,and the right inlet profile satisfying the automatic placement was thus obtained.
