摘要
"东方二号"勘探船由于实际使用需要,在船尾方向加设一个平台结构供放缆用。由于平台结构需要拖拽测量仪器和承受设备重量,所以需要对平台及相连主船体结构强度进行有限元方法计算分析。本文对放缆平台在实际使用中可能遇到的3种工况进行分析,并得出计算结果。通过数据结果,可以对放缆结构的抗弯、抗剪等强度具有整体的认识和局部细节的把握。结果还表明,平台结构端部及附近区域船体结构强度的等效应力,弯曲和剪切强度均符合规范要求。最后,还对结构提出了优化设计建议。
To achieve the purpose of shipping work, it needs to add platform structure following stern to Dong Fang II. Dong Fang II is a kind of exploration ship. In order to drag measure equipment and endure the weight of equipment, the structure strength of platform and main hull is analyzed by using Finite Element Method (FEM). This paper have analyzed the three possible cases and got the calculated results. Through the result datum, the bending strength and shear strength are recognized in whole view and local details. The results of the structure also explain that its strength satisfied the rules' standard at the end of the platform structure and its nearby area. At last, structure design is optimistic.
