摘　　要：以38万吨超大型矿砂船为计算对象,通过对舱段三维有限元结构建模方法、线外水压计算方法、舱内货物压力的计算方法以及端面施加弯矩等技术,形成了一种的超大型矿砂船舱段结构有限元强度校核的计算方法和评估体系,得出了船体甲板、外板、舷侧和舱壁等主要结构的应力,并真实地预报船体结构应力集中的区域,作为判断船体结构强度提供依据.也为后续的加强方案提供依据.Based on the 380 000 tons of very large ore carriers for computing object,through to the tank section of 3d finite element modeling method,the line outside the calculation method of hydraulic calculation method,cabinpressure of goods such as applying bending moment and transverse technology,formed a kind of super large ore sectionof cabin structure finite element strength checking calculation method and evaluation system,and obtained the hull,deck plate,side and bulkhead,stress of the main structure,and truly forecast hull structure stress concentration area,as a judgment of hull structural strength. It also provides a basis for subsequent strengthening programmes.
