舰船封闭式桅杆试验方法研究

封闭式桅杆因其良好的隐身性能在舰船上广泛应用。针对封闭式桅杆的结构设计,提出以典型结构部件试验、全结构缩比模型试验和实船跟踪测试试验为内容的多层次系列试验方法。对基于吸盘弹簧秤加载系统的风力作用下桅杆强度试验方法及用于测试摇摆作用下桅杆强度的倒置模型法等多种新的试验方法进行详细论述。结果表明,提出的试验方法准确性高、经济性好、可操作性强,可成功地对封闭式桅杆刚度、强度、振动等力学性能进行全面评估。

Experimental Methods for Enclosed Mast on Ships

Enclosed mast is widely used on ships due to its excellent stealth capability. Towards the structure design of the enclosed mast,a multi-level test scheme is proposed,including tests of typical structure members,proportional model of full structures and real-time tracking on board. Several new experimental means are discussed in details,such as mast strength tests due to wind loads by sucking disks and springs and due to swinging motion by an inverted-model. The results indicate that the proposed test metho...
