Research And Simulation Of Two-stroke Marine Main Engine Installation Process

The concept of "intelligence manufacture" and "China manufacture 2025" has been mentioned throughout the country recently,the shipping building as the important manufacture should be intelligentized is integrant.With the rapid development of modern computer science,the computer virtual simulation rapidly gets into every aspect of our shipping building.The simulation of main engine installation technology is one embodiment of shipping building intelligence,It is based on the two-dimensional technology design paper and using computer graphics software to establish the three-dimensional model of the Two-stroke Marine main engine.It also uses the three-dimensional graphics engine software to render the simulation model in order to achieve the virtual installation.It can make the fixing employees and the technics designers who are engaging the nain engine installation know the structure of Two-stroke Marine main engine,understand the requirements of installation.It improves effectively the installation precision of Two-stroke Marine main engine,avoids the installation and installation working repeated.In this paper,7G80ME-C9.5ship main engine being as an example(ME,it is the china single name Electronically Controlled Marine Engine,the same as the meaning of the paper),which is new product made by MAN company and it is a two stroke exhaust gas turbocharger-pressurizing,electric control technology,low speed diesel engine.According the different period and the installation precision of ME type main engine installed on board dockside,basing on the basic principles of volumetric model,the volumetric diesel engine model.Using 3ds MAX and MAYA software function to edit animation of main engine installation,import the animations into the three-dimensional graphics host software OGRE and Unity 3D to render under the framework of visual studio.net,using the visual C++software to edit operation interface.According the direction and aim of the research,the main content of this paper is:A brief account of the ME type main engine development history,knowing the structure and parts,during the shipping building dockside,the fission of engine for swinging,the installation technology process,parts installation order and requirements can be introduced.A brief aceount of the development state of the manufacture domain,knowing the main engine installation technology at present,using the virtual simulation resource,designing the main engine parts simulation models and platforms.Simulating the installation technology of ME type main engine,analyzing the simulation effect,it can offer the visualized design means,giving the installation convenience and accuracy.
