Abstract
Large uniform load on plane widely exists in the structural design of ship equipment. In order to verify the reasonability of equipment structural design, a test system of structural strength is needed to make structural test. To this end, a strength test system is developed. In this test system, a concentrated load, which is equal to actual uniform surface load that acts on the equipment, is imposed on the loading part by Hydraulic Loading Method. Then, the concentrated load is turned into several concentrated loads uniformly distributed in loaded area of the equipment structure. Stress measurement system is applied to make a tracking measurement of the series of points in the equipment structure. The test data is professionally recorded with a real-time analysis. In order to verify the feasibility of the test system, a complete test platform for a ship equipment structure is designed, furtherly a contrastive analysis has been undertaken between the outcome of the test system and the one of finite element simulation, and it turns out that the application of the test system is feasible.
Highlights
Large uniform load on plane widely exists in the structural design of ship equipment, as which is wellknown that it very complicated
According to the above comprehensive analysis, it is supposed that Hydraulic Loading Method (HLM) method is more suitable for the structural strength test of ship equipment with large uniform load on plane
There are many elastomers on this plane structure of the loading part, and the elastomers are Hydraulic Loading Method is used to load on Rigid Loaded Plane
Summary
Large uniform load on plane widely exists in the structural design of ship equipment, as which is wellknown that it very complicated. In order to verify the reasonability of equipment structural design, making a test on the structural strength of a new equipment model is usually necessary. In structural strength test, loading methods such as Gravity Loading Method (GLM), Hydraulic Loading Method (HLM), Mechanical Loading Method (MLM) and Pneumatic Loading Method (PLM) are usually used. Airbag design is one of the key technology of PLM, design method of uniform loading system using Airbags in structure strength test is brought out in S. In HLM method, comparatively, high load can be obtained. According to the above comprehensive analysis, it is supposed that HLM method is more suitable for the structural strength test of ship equipment with large uniform load on plane
