The genetic algorithm approach is used in this study to search for the optimal design values of pillar , deck stiffened panels , transverse web frames , flexible structures and side shell stiffened plates 在最佳化分析中采用基因演算法以随机搜寻方式寻找出汽车运送船上各层甲板中之支柱、加强肋板架、横向肋骨、侧板板架以及挠性结构的最佳化之设计尺寸。
A development for europe is this additional small barge board ( right arrow ) in front of the main one ( left arrow ) , connected to the protruding horizontal turning vane in similar fashion to a solution used by bar last year 主侧板（左边箭头）前面所增加的这个小侧板（右边箭头）是欧洲站的一个改进，它连接到突起的水平导向叶片上，类似于英美去年曾使用过的一个方案。
Furthermore , the dynamic responses of single deck supported by single pillar are also considered as for the fatigue strength analysis , the fatigue life assessment of the junctions of transverse web frame and side shell , and the junction of pillar and transverse web frame are investigated 在疲劳强度分析中，本文针对汽车运送船甲板下方横向桁材与侧板接合部分发及舱柱与横向桁材接合部分进行疲劳寿命分析。
The small board improves the aerodynamics in this area by diverting a small portion of the approaching airflow outwards , cleaning up the main central airflow , hence making it more effective in the way it passes it under the car and the way in which it cools the engine 这个小侧板可以将一小部分附近的气流导向外侧，使中心气流更加稳定，从而改善了这一区域的空气动力学，因此让气流通过赛车底部时更加有效，为引擎散热的效率更高。
Abstract : based on the theory of the structure dynamics , with the limited element sap5 programm as the calculating way , a calculatingway of the dynamics intenisity of the sieve " s lateral plate is put forward and the reason why this kind of oscillating sieve causes crcak on the lateral plate is analyzed 文摘:以结构力学理论为依据，以有限元sap5程序为计算手段，提出了一种直线振动筛侧板的动力学强度的计算方法，并分析了这类振动筛在侧板上产生裂纹的原因
