| 摘 要： | 给出一种船舶结构典型节点的参数化建模及形状优化方法,利用APDL建立某典型节点参数化模型的方法,将该节点形状参数定为设计变量,节点的应力集中系数作为优化设计的目标函数。通过不断改变形状参数,找出较小的应力集中系数。结果表明,该方法可有效降低应力集中,为舰船典型节点结构设计和优化提供参考。

| Abstract: | A parametric modeling and shape optimization method of a typical structural detail of warship is presented in this paper. First, a parametric model of a typical structural detail of warship is built by APDL. Then, the shape parameters of the structural detail are defined as design variables and the stress concentration factor of the structural detail is defined as the objective function of the optimization design. By changing shape parameters, a relatively small stress concentration factor is obtained. The ... |
