【摘要】 船体结构应力实时监测系统通过在船体结构中植入应变传感器实现对结构强度的实时监测与评估。文章对船体结构应力实时监测系统中应力监测点的选取方法进行了研究。通过全船结构有限元分析方法得到船体结构在外载荷作用下的结构应力响应,在此基础上对结构监测点进行选择,通过根据高应力部位和考虑海况信息两种途径对监测点进行选取,并依据选定监测点位置处的受力特点给出了传感器的布置方法,最后给出了一条船的应用实例。更多还原

【Abstract】 Ship structural stress real-time monitoring system (SSSRMS) achieves real-time monitoring and evaluation of the ship structure strength by implanting strain sensors on the hull structure. The method of the selection of stress monitoring points in SSSRMS was studied. The response functions of structure stress under external loads were obtained through the method of the whole ship structural finite element analysis. The monitoring points were selected in two methods which are finding the monitoring points on the area of high stress and considering the information of sea states. Then the method of strain sensor arrangement was presented according to the stress characteristics of the selected points. Finally, an application example was given.更多还原
