CAE Optimization Method Based on NURBS Curve Interpolation Technique

提出了一种基于 NU RBS曲线插值技术的 CAE优化方法。采用该方法对具有曲面形状的变截面梁结构建立了优化设计模型 ,介绍了该方法在 CAE中的优化过程。在通用有限元软件中采用参数化设计语言 APDL编制程序实现了目标函数的优化 。

Based on NURBS curve interpolation technique, a new CAE optimization method is proposed. By constructing a cantilever model with variable section, a concrete optimization process is developer and implemented in ANSYS, a commercial FEM system, with parameter design language developing tool APDL. Some examples showed that the method is correct and satisfied.
