本文对悬臂梁结构进行了模型数据参数化，利用Ansys Workbench对悬臂梁结构进行直接优化设计，建立以质量最小为最优目标的非线性多约束数学模型。通过计算和分析输入参数对优化目标的敏感性和响应（总变形和等效应力），确定最佳的优化方案。经过直接优化，该悬臂结构质量比原来减轻了47.8%，优化效果良好，达到了最初进行优化的目的，实现利用材料更经济的结果，为类似结构的轻量化设计提供了思路。本方法具有较好的可行性，可优化得到结构性能较好的悬臂结构几何布局方案，可为此类悬臂结构的轻量化优化设计提供技术支撑。
In the present paper, the cantilever beam structure is parameterized by model data, and the cantilever beam structure is directly optimized by Ansys Workbench. A nonlinear multi-constraint mathematical model with the best mass as the optimal target is established. By calculating and analyzing the sensitivity and responses (including total deformation and equivalent stress) of the input parameters to the optimization target, the optimal optimization scheme is determined. After direct optimization, the structural quality of cantilever beam is reduced by 47.8% compared with the original. The optimization effect is good, the conditions for initial optimization are achieved, the more economical results of the use of materials are realized, and the lightweight design of similar structures is provided with ideas. This method has good feasibility, can optimize the geometric layout scheme of cantilever beams with better structural performance, and can provide technical support for the lightweight optimized design of such cantilever beams.
