摘要
本文把相以理论应用于船体结构模型试验中。选取船体弯、扭特性参数作为基本物理量,以避免板厚等畸变因素,推导出大舱口船舶弯、扭相似准则和模型设计条件,并用相似变换将模型试验结果推证到实船上。通过两个相似模型的试验验证,证明预测是可靠的。同时,对大舱口江海直达货船的结构强度进行了分析。
This paper applies the similarity theory to the model test of the ship's structure, derives the similarity principles of bending and torsion of the large-hatch ships, and finds out the requirements of the model design. The results of the model test are inferred to a real ship. The preestimate and conclusion can be used as reference by the design department in revising the plan of this ship.
