主要进行了如下几个方面的工作：参数化有限元模型的建立；修正模型设计参数、约束及目标函数的确定；灵敏度方法的比较及优化算法的选取；固有振型的获取及模态相关性的定量描述；采用结构优化技术解决有限元模型修正问题。在模态修正过程中，由于修正固有振型涉及大量的有限元计算结果数据，此前，虽有不少文献在理论上研究了它的修正方法，但都没有给出工程应用实例，而本文解决了固有振型修正的工程应用问题。 - The paper defines the objective function as : minimizing the quantity of works under the condition of enough water area and depth according with the national codes . the paper narrates the development and main technology of ga , and changes the above problem with restraint conditions into the maximizing problem without restraint conditions , the way the paper chooses is the punish function method
