摘要/Abstract

摘要： 为有效监测破冰船总纵弯矩,该文引入了改良的形函数法与测点布置策略以提升船体弯矩识别精度：首先,通过数值分析方法,以某破冰船体舱段为研究对象,探讨了适用于形函数法的求解策略及其正则化参数选取策略;随后,针对破冰船应力分布复杂的问题,提出了一种测点布置策略并进行了验证。结果表明：L曲线准则与硬阈值选取策略均能提升改良形函数法的精度,提出的测点布置策略能有效提升弯矩识别的稳定性,所建立的弯矩识别方案可为破冰船弯矩识别提供一种改进思路。

关键词: 弯矩监测, 测点布置, 形函数法, 正则化参数

Abstract: To effectively monitor the total longitudinal bending moment of icebreakers, an improved shape function method and a measurement point layout strategy were introduced to enhance the accuracy of hull bending moment identification. First, through numerical analysis, hull section of an icebreaker was taken as the research object, and the solution strategy applicable to the shape function method and its regularization parameter selection strategy were investigated. Subsequently, to address the complex stress distribution of icebreakers, a measurement point layout strategy was proposed and validated. The results show that both the L-curve criterion and the hard threshold selection strategy can improve the accuracy of the improved shape function method. The proposed measurement point layout strategy can effectively improve the stability of bending moment identification. The bending moment identification scheme established in this study provides an improved approach for bending moment identification of icebreakers.

Key words: bending moment monitoring, measurement point layout, shape function method, regularization parameter
