对复合材料曲面数字化展开方法的论述表明,采用纯几何的方法进行展开,模型相对简单,但适用范围有限;采用力学模型模拟能够更贴近实际情况,但是计算量比较大,而且边界条件、初始解不易获取,展开效率不高,有待于算法的进一步提高;采用几何与力学相结合的方法,再加上相应的工艺约束,能够快速得到满足工程实际的复合材料曲面展开结果,将是复合材料数字化展开的一个发展方向。
The discussion of the digital expansion method of composite curved surface shows that the method of pure geometric expansion is relatively simple, but its application scope is limited. The mechanical model simulation can be closer to the actual situation, but the calculation is relatively large, and the boundary conditions, initial solution Not easy to get, expand the efficiency is not high, to be further improved algorithm; using a combination of geometry and mechanics, coupled with the corresponding process constraints, can quickly get the project to meet the actual composite surface expansion results will be digital composite Expand a direction of development.
