Razvoj metoda za određivanje tehničkih i eksploatacionih parametara brodova potiskivača i potiskivanih sastava / Developing methods for determining technical and exploitation parameters of pushboats and pushed convoys

<p>Kretanje potiskivanog sklopa/sastava je njegova sposobnost da se premešta<br />nekom brzinom usled delovanja određene sile koja mu je pridodata.Ovu silu<br />stvaraju brodski propeleri i pri zadatoj brzini v=const ona treba da bude<br />jednaka sili otpora sredine-vode i vazduha.Iz tog razloga korisna sila koju<br />razvijaju propeleri broda-potiskivača pri plovidbi sa sastavom potisnica<br />pri v=const treba da savlada ne samo otpor svih potisnica u sastavu već i<br />sopstveni otpor broda. Za planere procesa vodnog prevoženja neophodno je,<br />osim poznavanja veličine otpora sredine pri plovidbi potiskivanih<br />sklopova i poznavanje redukovanih i specifičnih otpora pojedinih tipova<br />potiskivanih teretnjaka i sastva koje oni čine. Osim toga, predložene su<br />metode za proračun očekivanih brzina plovidbe u mirnoj vodi i očekivanih<br />vrednosti pokazatelja statičkog opterećenja utvrđenih na osnovu obavljenih<br />eksperimenata po pojedinim tipovima brodova i potiskivanih sastva. Takođe,<br />predloženi su novi tehnički i eksploatacioni pokazatelji za ocenu<br />ispravnosti rada potiskivača, koji do sada nisu primenjivani u Srbiji. Na<br />kraju disertacije prikazane su metode kojima se rešavaju praktični zadaci<br />prevoženja po različitimh brodovima potiskivačima i potiskivanim<br />sastavima.</p> / <p>Movement of convoy/pushed convoy is its ability to change place due to certain<br />force that drives it. This force is created by ship&rsquo;s propellers for given speed v=const<br />and it should be equal to resistance of surrounding water and air. This is the reason<br />why useful force created by ships propellers (thrust) created by propellers of pushboat<br />while navigating with a convoy at v=const needs to overcome not only the<br />resistance of barges but push-boat&rsquo;s resistance as well. For planers of transport<br />process it is necessary to know, besides the resistance of surroundings during<br />navigation of pushed convoys, the value of reduced and specific resistance for certain<br />types of barges and convoys that they form. Apart from that methods for calculation<br />of expected speeds of navigation, value of static load of engines based on<br />experimental research. Besides that new exploitation parameters for determination of<br />push-boat&rsquo;s work are proposed, which haven&rsquo;t been used in Serbia. At the end<br />dissertation presents methods to solve practical transportation tasks for different<br />ships with different convoys.</p>
