快速组合火车渡轮模型实验研究

Experiment Study of Model of Quick Assembled Train Ferry

快速组合渡轮是由两条驳船联接而成 ,在联接处可以纵向相对转动。根据两驳船在联接处力的传递特征 ,分别采用薄壁梁弯曲方程和约束扭转方程作为相似模拟的控制方程 ,进行了相似模型设计和实际船舶与模型的外力转换。在模型试验中 ,从组合渡轮的实际受力状态出发 ,模拟了不同的外力组合 ,得到了联接附体及其附近的部分船体上的应力分布规律。

The so-called quick assembled train ferry is formed by longitudinally jointing two barges together with a permissible capability of limited turning of one barge in respect to the other at the joint.In this paper,some explorations are made in test method and similitude design of a moveable assembled model.On the basis of the characteristics of force transmission at the joint of the barges,a similitude model is designed and tested by means of similitude theory.In the tests,according to the actual forces exerted on the assembled ferrys,several combinations of load forces are simulated.A stress distribution in the jointing members and their surrounding areas of the barge hulls is obtained.
