船体自然寿命分析

摘要

Assessment of natural life of warship hull plays the most important part in the life assessment of warship hull. Natural life of warship hull is evaluated in view of hull intensity. The factors related to the hull natural life and the hull corrupt laws are demonstrated after the definition of hull life. Then warship hull's natural life is analyzed according to the relation between the hull intensity after corrosion and the stated allowable intensity of ship hull. An example is presented at last. It is indicated that this method is reliable and practical.%舰艇船体自然寿命的分析在船体寿命分析中有至关重要的作用,该文从船体强度的观点来分析船体的自然寿命.首先,给出船体寿命的定义,并据此对制约船体自然寿命的一些因素及船体腐蚀规律做了论证;然后,根据耗损后的船体强度与规定的船体强度衡准之间的关系来确定船体自然寿命;最后,结合某型舰艇,利用上述方法,对其船体自然寿命进行了计算仿真.实例表明:该评定方法结论可靠,简便易行,利于工程实践应用.
