3d setting simulation method for accuracy of erection block and one time setting for ship building yard

摘要

PURPOSE: A block mounting estimation management method for a shipbuilding yard is provided to systematically manage a three dimensional precision degree of an internal assembly block and an external mounting block for implementing one time block setting as soon as the block is assembled or mounted. CONSTITUTION: The method comprises several steps. A server for managing a design and measurement data file, supporting a shipbuilding design and estimating a block mounting is constructed, a three dimensional precision degree of an internal assembly block and an external mounting block is measured, a precision degree data file is stored at the server, and the precision degree data is shared via all the steps. A length, a numerical equation, a horizontal precision degree error and others relevant to each block are analyzed by comparing the measurement data file with the drawing data file, and the analysis data is stored at a database. A length error, a re-cut amount and gap data is displayed by performing a simulation based on the three dimensional measurement data of the assembly and the mounting block. A pre-finishing drawing construction is performed by analyzing the measurement data of the blocks, to mount and to be mounted, in order to reduce a dock task, e.g., to re-cut the blocks or to release the blocks. All the data on the block design and the block measurement are collected, analysed and stored at a database.
