The Preliminary Study On Integrates Method Of Cross Platform Ship Total Performance Visual Test System

The Visual Test technology already uses in the actual production process in the project domain, particularly in domains aerospace, automobile, weapon manufacture, already the part or substituted the material object test completely, has saved the massive manpower and resources; The ships domain's visual test technology also occupies a start stage, no matter is domestic or overseas, very little has may utilize in the project practice mature product.This article introduced the concept and the principle of visual test technology, present application situation of domestic and foreign, "Ships Overall Visual Test System" background and correlation progress. Through to the different system integration method's contrast research, had determined the system integration plan, constructed the system overall architecture, and take the hypothesized test control center which independently designs as the foundation platform, realizes to user account, the test flow and the test data management.Has analyzed the marine environment database unique feature, and has designed the interface between visual test system and the marine environment database, through this connection real-time gain sea area wave statistical data, has provided the good data support for the construction value wave testing environment; Realizes using the Windows dynamic link library technology to transfer data and alternate data between the 3D dynamic sea condition display module and the marine environment database, has completed to the testing environment choice and the three-dimensional display.Used the XML documents technology to complete the hull design software and the visual test system data conversion, and has designed the XML documents structure and the test system database connection, caused the ships test model document to import the visual test system correctly, and integrated the VB+OpenGL 3D dynamic examination module, realized the test object visualization; Uses Windows Shell technology realizes to the ships overall performance hypothesized test subsystem's integration and the test data (for example wave data) interaction; Uses Windows Shell and the WindowsAPI technology realizes to the ships structure performance visual test subsystem's integration.Based on the integration project design system user interface, has established the related function procedure code, has linked up"testing environment-test object-test item"the test flow, and realizes to the military vessel digitized test and the confirmation at design stage. The systems operation is stable, the reliability is high. To the visual test technology in our country ships domain's application, has made the preliminary exploration and the practice, hoped that to enhances the informationization degree of our country shipbuilding industry, as well as the innovation ships model verification technology aspect, has certain influence.
