Abstract

The invention relates to a device for measuring liquid sloshing force, which belongs to the technical fields of shipbuilding and ocean engineering, and experiment testing. This device for measuring liquid sloshing force includes a force-measuring frame and a liquid cabin mechanism. The force-measuring frame includes a rectangular force-measuring frame mechanism, a pocket frame mechanism, a rotating shaft mechanism and a force-measuring mechanism. The liquid cabin mechanism is placed in the pocket frame mechanism, and the pocket frame The mechanism is connected to the rectangular force-measuring frame mechanism through the rotating shaft mechanism, and the force-measuring mechanism is connected to the rectangular force-measuring frame mechanism and the pocket frame mechanism. The device has the characteristics of light weight, simple structure, convenient combination, convenient operation, high measurement accuracy and strong versatility. This device for measuring liquid sloshing force can be placed on the swaying excitation platform for use. When a certain amount of liquid is filled in the liquid chamber mechanism, the swaying excitation platform shakes, causing the liquid in the liquid chamber mechanism to slosh, and the liquid sloshing force passes through the pocket frame. The mechanism is transmitted to the force measuring mechanism, and the tension meter can measure parameters such as liquid sloshing force.

Description

technical field [0001] The invention relates to a device for measuring liquid sloshing force, which belongs to the technical field of ships and ocean engineering, and experiment testing. Background technique [0002] Ship liquid storage cargo tanks are developing towards super-large volumes. Under the excitation of external shaking, the liquid in the cabin will also slosh and flow. When the tank is partially loaded, the problem of liquid sloshing in the cabin will become more obvious. The impact load caused by sloshing can cause a large structural response of the bulkhead structure, and even lead to the destruction of the tank bulkhead structure, resulting in huge economic losses. Therefore, a key mechanical problem in the structural design of shipboard tank bulkheads is the evaluation of the sloshing impact load in the tank. The loads and effects caused by sloshing have become one of the important contents of the safety assessment of liquid-carrying ships during navigation...
