By observing the master storms direction and load status under various sea conditions, SWAN system can calculate a safe speed and ship maneuvering envelope plotted in Fig. This allows the master to be determined within the scope of manipulating the envelope on how to reduce speed and change course. For large and fast ships (such as container ships), if the speed from 14 down to 10, the calculation by DNV, the bow shock wave can be reduced by half.
In order to meet the market demand processing depends largely on the compound, and therefore, only the interaction of all of the compounds are considered to be the program is successful. To target material required soft phase (Softphase) component minimized, the first step is to test the material. Miba has to test the range of the target material is determined as 2128% tin content, the matrix Enhancer 2 a 3.5%.
In this alloy series selected to do the test, there are four variations, which is the ratio of the difference that they contain the content of several elements is not the same. Aluminum tin alloy is cast using integrated technology - mainly the continuous casting technology casting, followed by annealing after casting and milling around the cast off skin.
Four alloys by three continuous casting plant using different processes (horizontal and vertical continuous casting continuous casting machine casting) after the processing by the Miba company into a bush, then detects the impact on the processing performance of the casting process. In order to meet the needs of users for more affordable, more reliable performance and longevity of the engine parts, Miba Bearing branch company developed a performance with three metal bearing considerable, bearing a lower price than a new generation of bi-metal aluminum based alloy bimetal bearings.
According Miba company, a new generation of bi-metal bearing fatigue strength than conventional bi-metal bearing 20%, the friction properties comparable with AISn20 bearing, and the increased costs will not exceed 10%. Due to the nature of the bearing alloy composition except outside.
Do with used bearing metallurgical test friction characteristics can be measured, the test results can also be used to determine possible ways for further processing. The test results and material composition and processing methods are compared, it is possible to determine the chemical composition of the alloy. Selected chemical composition can keep the bearings in good strength and operational characteristics. In the manufacture of a layered compound increases process reliability, an issue important consideration is to provide a wide range of processing parameters.
The entire development process, including the casting process and select the matching material composition, despite the high tin content of the finished bearing, but with a very fine structure. Another important feature is the middle layer AIZn4.5 can withstand high loads. In order to meet the requirements and processing of such bearings, Miba has designed computer-controlled tape strip continuous casting lines, and to determine the carrying capacity of the bearing by installed for testing.
