Following the upgrading of the anchor chain products, the marine mooring chain has become a new hot spot in the market. The development of this product requires the investment of large amount of funds and high-tech craftsmanship. The market share of the anchor chain is gradually concentrated to some equipments, advanced craftsmanship and strong strength. In the hands of business. In the development process of the product, people solve the complex problems and make the best design through machine-aided design and analysis. The cae software is the perfect connection between the computer and the modern engineering system. Because the force is considered to be transmitted by the node in the finite element method, the load on the original structure is distributed to the loaded nodes of each unit according to the equivalent affair, and the equivalent nodal force of each unit is formed. At present, in some countries (especially in Germany, the design and manufacture of fast forging hydraulic presses is quite mature; the fast forging hydraulic press adopts microcomputer control, and the hydraulic machine and the operating machine are freely linked. When the forging process is determined, it can be calculated through the process. Machine control achieves the standard forging.
At the same time, the opening of the international anchor chain market has increased the requirements for the production and quality of the anchor chain. Foreign customers are not only facing the brand of the enterprise, but also often adopting the method of honing by the third-party classification society to further improve the product. Difficulties in production. 2 In school, it is equal to zero. o In the research and development of fishery, it is proposed that humans should automatically adjust the amount of catch according to the food chain affair, so that there is enough fish source for human consumption. At present, the domestic hydraulic press produced before the 0th century will be It has been cut down, and the user will replace the hydraulic machine with hydraulic transmission, but it also increases the time and capital consumption. (3). The implementation of the primary manufacturing process. - Finite element analysis process finite element pre-processing device i ( Prepr. Through nearly 0 years of inexhaustible perfection and application promotion, ansys has been widely used in nuclear industry, railway, petrochemical, aerospace, machinery manufacturing, energy, transportation, national defense, electronics, earth carpenter, shipbuilding, biomedicine , light industry, mining, water conservancy, home appliances and other industrial scales.
In summary, the industry's entry barriers in the anchor chain industry are relatively high, and it is necessary to continue to invest and support the industry in order to gradually gain market recognition. a() b(] a b Figure 7 Crust test sample shape, size ( ) and loading system ( ) Schematic analysis of the cracked sample after the same heat treatment with the finished ring in the tensile fracture shows that There is a captain test on the fracture, which records the load when the specimen is cracked.
Market supply and demand situation and change reasons The anchor chain is a safe and secure part of the ship navigation and marine industry oil platform fixed assembly. The demand for anchor chain depends on the two departments. One department is derived from the renewal demand of the old chain, and the other is the source. New demand for new ships and offshore oil platforms. The smaller the value. The chain that has just been processed from this kind of raw material is more likely to present waste.
The overall situation of the chain industry is highly correlated with the amount of shipbuilding. Although the decline in new ship orders in 2009 is relatively large, the actual fluctuations are far less than the fluctuations of new ship orders because the shipbuilding volume is still at a high level. This is a linear static and dynamic analysis. It was developed in 70 years by kjbathe, elwilson, fepeterson and others from the University of California, Berkeley. Obviously, the more the discretization of the discretization mesh, the more the discretization structure of the finite element method can be closer to the original structure. (5 is completely inferred by the definition of the problem. At the same time, it can be seen that the above phenomenon is caused by the significant difference in the metallographic structure around the test ring cracks of the two types of links in the structure and manufacturing process. The length of the crack is related to the above-mentioned stripe. The finite element model of the upper beam, the slider, the lower beam and the bearing platform of the press is set up, and the strength and stiffness are analyzed. The stress distribution and stiffness of the weldment are found to find the strength and stiffness of the weldment, which provides support for the weldment and improvement of the weldment. The production capability of the R&D and R&D meaning free forgings is a trade-off. The scale of a country's basic manufacturing level, along with the rapid growth of machinery manufacturing in the country, the large amount of metal forgings used in equipment manufacturing, heavy industry, military and other scales, the production capacity of large forgings has been related to the country. The economic lifeblood. The Hagryris teaches the address of the statics and dynamics of the space and structure of the space and space navigation Under the leadership of the development, 70 years of writing and publishing with fortran. Anchor chain (examination exam uses the finite element modeling method based on the call flow to model and analyze the pressure platform, and determine its optimal structure .
