摘要/Abstract

摘要： 以海洋工程中含裂纹钢板为研究对象,通过虚拟裂纹闭合法建立有限元仿真模型,模拟塑性钢板加固前后的承载能力,并分析胶粘剂的剪切强度和延伸率对加固性能的影响。设计相应的加固试验模型,对比经过交变湿热、太阳辐射老化、盐雾等海洋环境试验前后的结构加固性能,并选用适合海洋环境的胶粘剂进行加固方案的优化。研究表明,改变胶粘剂的性能参数对加固结构的屈服点影响不大,但对复合材料加固的极限承载能力影响较大。海洋环境因素可导致胶粘剂的性能下降,选用适合海洋环境的优异胶粘剂后可提高加固的可靠性和耐久性。

Abstract: Steel structure with crack used in marine engineering is the object of study. Tensile properties of steel plates reinforced by CFRP is simulated by the model established with virtual fracture closure method. The influence of shear strength and elongation of the adhesive on the reinforcement was analyzed and compared. The effect of marine environment factors such as alternating hot and humid, salt mist and strong solar radiation is studied by model test. The reinforcement program is optimized through using marine-resistant adhesive. The results show that the properties of adhesive has little effect on the yield point of reinforcement structure, but it can influence the ultimate capacity obviously. The performance of adhesive can be decreased by environment factors. Reliability and durability of reinforcement can be improved by using marine-resistant and excellent adhesive.

Key words: composite reinforcement, crack, adhesive, environment test, tensile properties
