Ansys_Workbench优化模块结合极限载荷分析在工程设计中的应用

Application of Ansys_Workbench Optimization Module Combined with Limit Load Analysis in Engineering Design

分析设计中的应力分类法无法区分一次和二次弯曲应力,在工程设计中往往会出现或保守或冒进的弊端;极限载荷分析法可避免应力分类法的缺陷,在评定准则和结果的准确性方面优于应力分类法,在一定情况下可作为应力分类法的弥补验证方法。本文将这2种方法相结合,基于有限元软件Ansys_Workbench中的Direct Optimization优化模块,提出了一种结构优化方法,并以工程实际模型为例,详细阐述了该优化方法实施的具体思路和步骤,以期能为工程设计提供一定的思考和研究。

The stress classification method in analysis design can not distinguish primary and secondary bending stress, which often appears conservative or reckless in engineering design. The limit load analysis method can avoid the defects of stress classification method and is superior in the accuracy of evaluation criteria and results, which can be used as a compensatory verification method for stress classification method under certain circumstances. This paper combines these two methods, proposes a structure optimization method based on the Direct Optimization module in the finite element software Ansys_Workbench, and takes the actual engineering model as an example to elaborate the specific ideas and steps of the implementation of the optimization method. In order to provide some thinking and research for engineering design.
