摘要

为实现船体加筋板结构的抗碰撞能力快速预报，本文提出了船体加筋板结构在球鼻艏撞击下发生大变形至破裂过程的耐撞性解析预报方法。针对大变形过程，提出了板及其附连加筋的理论变形模式，并基于塑性力学相关理论，得到了板和加筋的变形抗力计算公式；针对初始破裂，提出了板的临界撞深计算公式，考虑加筋与板的耦合作用，推导了加筋对板临界撞深的影响计算公式，最终建立了加筋板的临界撞深计算方法。通过模型试验验证了所提解析预报公式的准确性。本文研究成果对船体加筋板耐撞性的准确快速评估有一定贡献。

Abstract

In order to predict the crashworthiness of stiffened ship panels rapidly, an analytical method to obtain the crashworthiness of stiffened ship panels collided by a bulbous bow was proposed in the present paper. Stiffened ship panels will experience large deformation to initial fracture. For the large deformation process, the theoretical deformation modes for the plate and the attached stiffeners were proposed. Moreover, the deformation resistances for the plate and the attached stiffeners were obtained according to the theory of plastic mechanics. For the initial fracture, the expression to obtain the critical penetration depth of the plate was built. In addition, the expression to calculate the influence of the stiffener on the critical penetration depth of the plate was derived by considering the coupling effect between the stiffener and the plate. The method to obtain the critical penetration depth of the stiffened panels was finally established. Moreover, model tests were performed to validate the accuracy of the proposed analytical expressions. The research in this paper is a contribution for accurate and rapid assessment of the crashworthiness of stiffened ship panels.
