Problems solved by technology

For the strong nonlinear phenomenon of slamming, pure theoretical calculations cannot meet the designer's requirements in many aspects, so it is very necessary to develop a hull model wave slamming model that can effectively simulate the slamming phenomenon that occurs in actual ship navigation. The impact load test device is used to conduct in-depth research on the ubiquitous but very dangerous slamming phenomenon between the hull and waves at certain speeds

Embodiment Construction

[0021] The present invention will be described in more detail below with examples in conjunction with the accompanying drawings.

[0022] combine figure 1 and figure 2 , The two-dimensional motion slamming test device of the present invention is mainly composed of three parts: a moving bracket, a sliding module and a lifting module. The mobile bracket is composed of a truss structure 1 across the pool and rolling wheels 3 running along the track 2 of the drag pool. The sliding module consists of a steel outer frame 4, stainless steel rails 5 and connecting members 6 that can slide on the rails. Lifting module is made up of electric hoist 7 and electromagnet 8. There is an adjustment gap between the outer frame and the steel rail.

[0023] Simultaneously combine image 3 and Figure 4 , the scroll wheel is installed on the lower end of the mobile bracket by the shaft and the bearing 14, and the first guide wheel 16 is set by the guide wheel shaft and the bearing 15 on bo...

Abstract

The invention provides a two-dimensional motion slamming test device. The two-dimensional motion slamming test device comprises a mobile bracket, a gliding module and a hoisting module, wherein a lower portion of the mobile bracket is provided with a rolling wheel, the mobile bracket is arranged at a track of a towing tank through the rolling wheel, the gliding module comprises an outer framework mounted on the mobile bracket, four steel trails mounted on the outer framework, and connection components sliding on the steel rails, and the hoisting module comprises a crane mounted at a top portion of the outer framework and an electromagnet connected with a lower portion of the crane. The two-dimensional motion slamming test device is mainly used for simulating a phenomenon of a hull slamming with waves during two-dimensional motion and measures change of a slamming load in a slamming process in real time. The two-dimensional motion slamming test device can accurately reflect a practical situation of the underway hull slamming with the waves.

Description

technical field [0001] The invention relates to a test device for testing the wave slamming load of a hull model under the condition of a certain speed. Background technique [0002] When a ship sails in harsh sea conditions, due to its own large-scale swaying motion, the ship will inevitably have a severe impact with the waves. It is usually said that the short-term and large-amplitude transient load on this ship is Ship "slamming loads". Severe slamming loads can lead to damage to the local structure of the hull and even endanger the survival of the entire ship. Therefore, it is very necessary to accurately predict the slamming load of the ship in the ship design stage. For the strong nonlinear phenomenon of slamming, pure theoretical calculations cannot meet the designer's requirements in many aspects, so it is very necessary to develop a hull model wave slamming model that can effectively simulate the slamming phenomenon that occurs in actual ship navigation. The impac...
