关于大型结构物运输时驳船强度分析

Barge strength analysis on intensity of a module transportment

运用SACS软件对大型结构物进行建模,根据API[1]规范,计算得到大型结构物运输时各个桩腿的支反力,并采用ANSYS软件对船舶进行了受力分析,获得了应力、应变和位移结果,通过分析结果,确定了驳船容易损坏的部位,在此基础上对大型结构物滑移装船过程和运输过程时驳船强度的要求提出了较为科学的建议,对如何降低结构物装船、运输过程的驳船应力提供依据。

According to the API specification,the use of SACS software is modeling structure and calculating the reaction force of each leg when the module is transporting process. The stress,strain and displacement result are obtained by using ANSYS software analyzing the ship. By ana-lyzing the results,determine the position of barge which is easily damaged. On the basis of the module loadout and transport barge strength re-quirements put forward more scientific recommendations,provide the basis for how to reduce the structure loading,transport barge stress.
