【摘要】：导管架平台遭受船舶撞击的事故,将造成严重的经济损失和环境污染。在结构设计中应当对平台圆形管柱结构的抗撞性能予以足够重视。在结构设计时,通过解析计算方法预报圆形管柱结构的抗撞性能,可以显著提高结构设计效率。在圆形管柱碰撞损伤机理研究的基础上,考虑圆形管柱遭受撞击时的整体弯曲变形,提出了一套预报圆形管柱抗撞性的解析计算方法;利用该方法,对圆形管柱结构遭受船舶侧向撞击场景下的管柱结构损伤、结构变形阻力,开展解析计算分析和预报。研究中采用落锤撞击圆形管柱试验,以及数值仿真方法,验证该解析计算方法的准确性,提高其在导管架平台结构设计中的适用性。
[Abstract]:The collision of jacket platform will cause serious economic loss and environmental pollution. In structural design, sufficient attention should be paid to the crashworthiness of the platform circular pipe string structure. In structural design, the efficiency of structural design can be greatly improved by using analytical calculation method to predict the crashworthiness of circular tubular column structure. On the basis of the research on the damage mechanism of circular string in collision, a set of analytical calculation methods for predicting the collision resistance of circular string are put forward considering the whole bending deformation of circular string under impact, and the method is used to predict the collision resistance of circular pipe string. The damage and deformation resistance of circular string structure under the circumstance of ship lateral impact are analyzed and forecasted. The accuracy of the analytical calculation method is verified by using drop hammer impact test and numerical simulation method to improve its applicability in the design of jacket platform structure.
