摘要
针对国内梁结构优化设计应用研究领域的不足,利用有限元及CAE计算机仿真技术对梁的截面进行以减轻质量为目标的结构优化分析。首先利用Hypermesh进行梁截面的网格划分,其次考虑梁截面的受力方向不同,使用OptiStruct进行模式重复情况下的拓扑优化。最终依据优化结果,对梁截面进行二次设计和工艺优化,以获得满足挠度条件的最轻梁结构。得出了利用有限元及CAE计算机仿真技术进行梁结构优化的一般思路和可行的办法。
The finite element and computer simulation technology was used to optimize the structure of beam in order to reduce quality objection. First the element of the beam was built up. Second topology optimization with pattern repetitions was performed under the condition of different force. Finally, the beam was designed again to obtain the lightest structure of beam satisfied deflection condition according to the result of optimization. The viable method and ideas based on finite element and CAE computer simulation technology was given.
