Mechanized Computation of Ship Parameters

摘要

For the purpose of vibration and load analysis a ship hull is often regarded as a flexural beam. The report describes a method and numerical computer (digital) program to calculate ship section properties (i.e., equivalent beam parameters) needed for the beam vibration equations and its internal shear distribution, using data tabulations obtained from hull plans by a preestablished orderly procedure. The program was written in FORTRAN and can be used on an IBM 650, 704, 709, or 7090. Comparison between digital computer and hand calculations for a sample problem shows excellent agreement. (Author)
