Problems solved by technology

[0003] The full cushion lift hovercraft has a complex structure and is equipped with various air channels. It not only has high requirements for watertightness, but also has very strict requirements for the airtightness of the ship model; at the same time, it is much lighter in weight than conventional ship models. Controls are also quite demanding, especially in the design, fabrication and installation of load testing devices
Therefore, the load model of the full cushion lift hovercraft is relatively difficult in the design of the overall structure, and it is still blank in the prior art

Embodiment Construction

[0020] Such as figure 1 As shown, the hull of the hovercraft model adopts a segmented structure and is composed of 6 modules. There are gaps 9 between the modules, and the modules are connected and fixed by measuring beams 7 (ie, strain balances). The hull is divided horizontally at the middle position of the hull and at the position 1 / 4 of the length from the bow, and the hull is divided longitudinally at the position corresponding to the central axis of the hull. The hull is divided into 6 modules, which are left front module 1, left middle module Rear module 3, right front module 4, right middle module 5, right rear module 6. Between the left front module 1 and the left middle module 2, between the left middle module 2 and the left rear module 3, between the right front module 4 and the right middle module 5, between the right middle module 5 and the right rear module 6 are connected and fixed by measuring beams , between the left front module 1 and the right front module ...

Abstract

The invention relates to a sectional wave load testing model for an air cushion vehicle. The model comprises an air cushion vehicle model body, and is characterized in that the air cushion vehicle model body has a sectional structure, and consists of six modules, wherein a gap is formed between every two adjacent modules; the modules are fixedly connected through measurement beams.

Description

technical field [0001] The invention relates to a segmented full-cushion lift hovercraft wave load test model. Background technique [0002] Due to the complex motion of the full-cushion hovercraft, there are also great differences compared with conventional ships, which brings great difficulties to the theoretical calculation of wave loads. The specification of the structural strength of the full lift hovercraft is only involved in a small part in the "Code for High-Speed ​​Ships", and the calculation methods of the hovercraft wave bending moment in the specification are also obtained based on the wave load theory of planing boats. Therefore, in order to provide a valuable test basis for the structural strength evaluation of the full-lift hovercraft, as well as the theoretical calculation of the wave load and the structural design of the full-lift hovercraft, it is very necessary to carry out the load model test of the full-lift hovercraft. [0003] The full cushion lift h...
