摘要: 以安全箱卡扣为研究对象,首先,基于响应面优化理论,采用响应面设计(BBD,Box-Behnkendesign)法设计随机试验并构建回归方程,进行目标优化。其次,选取不同卡扣长度、宽度、厚度、底侧圆角作为参数进行模型设计,按照设计参数进行建模和有限元仿真分析;构建参数和响应量间的回归方程,以最大应力为优化目标进行优化求解。最后,对优化后的卡扣设计方案进行验证,可为卡扣设计探索一种新的优化设计方法。

Abstract: Taking the safety box buckle as the research object, based on the response surface optimization theory, regression equations is firstly constructed to optimize the objectives, and Box-Behnken design (BBD) method is applied to design random experiments. The different lengths, widths, thicknesses, and fillets of the bottom side of the buckle are selected as parameters for model design, modeling and finite element simulation analysis are performed ac鄄 cording to the design parameters. The regression equation between the parameters and the response is construct鄄 ed, and the maximum stress is taken as the optimization goal to optimize the solution. Finally the optimized plan is verified, which can provide a novel optimization method for the design of the buckle.
