摘要
利用有限元分析软件ANSYS Workbench对某升船机承船厢卧倒门进行参数化建模,定义了包括板厚与主梁间距在内的10个设计变量.根据有限元结构静力分析的结果,综合结构灵敏度分析,确定每个设计参数对卧倒门结构质量、综合应力与综合位移的影响程度,以结构板厚、主梁间距为设计变量,以最大综合应力与综合位移为约束条件,以结构质量为目标变量进行优化设计.通过目标驱动优化(GDO)中的筛选法(Screening),选出最佳设计点,实现了6.8%的质量优化.参数化建模实现了整个卧倒门的参数化管理,在很大程度上提高卧倒门的设计优化效率.
The finite element analysis software ANSYS Workbench is used for parametric modeling of the horizontal type gate of shiplift chamber. According to the results of finite element structural static analysis, comprehensive structural sensitivity analysis to identify the influence degree of each design paramete on structural mass, von mises stress and displacement vector sum, taking structural plate thickness, pri- mary beam spacing as design variables, the maximum stress and integrated displacement as constraints, the structural mass as the target, through the screening method in goal-driven optimization, the best de- sign point is selectd. And then 6.8% optimization in mass is achieved. Parametric modeling makes it possi- ble to manage the model parametricly and can largely improve the efficiency of optimam design.
