气浮结构相似性分析

提出了有关气浮结构的环境压力相似判据问题，指出了在模型试验时要达到完全相似的困难。计算结果表明，对尺度比为0．1的模型，若不考虑环境压力的相似，恢复力矩的误差可接近50％。根据4筒和25筒气浮结构的计算结果，给出了将实验结果转换到原型的修正方法。

Similarity analysis of air floating structures

In this paper, the similarity of circumstance pressure of air floating structures is investigated. The difficulty in the perfect similarity for model experiments is indicated. The computational results show that the error of restored moment can be 50% for the model with a scale ratio of 0.1 when the similarity of environment pressure is not taken into consideration. Based on the computational results of 4 air floating cylinders and 25 cylinders, the modified method for transforming model experiment results to the prototype is presented.
