Annotation

To ensure the specified accuracy, reduce the amount of work on straightening structures and minimize the amount of fitting work, it is important to select the optimal sequence of assembly and welding work and effective measures aimed at reducing and compensating for expected welding deformations. This is achieved by using calculation methods when designing the manufacturing technology of the structure. In general, ship hull structures are characterized by significant dimensions, complex contour shapes and a large number of welds of varying lengths and orientations relative to the base planes. This complicates the use of analytical formulas for estimating the parameters of welding deformations and makes it reasonable to use numerical methods for these calculations. The report discusses a method for calculating expected welding deformations based on the finite element method (FEM) and provides examples of its use for ship hull structures. Keywords: shipbuilding, welding deformations, hull structures, technology, calculation, finite element method.
