STRUCTURAL TESTS OF SL-7 SHIP MODEL (SL-7-11)

A steel structural 1:50 model test program has been conducted for the 942-ft., 33-knots, SL-7 Containership. This report describes development of the model, through the test program and then to the test results. The principal stresses measured were longitudinal normal stresses and shear stresses. The model was loaded by means of calibrated steel weights and precision pulleys. The vertical and lateral bending responses corresponded closely to elementary beam theory; the vertical shear amidships pattern appeared to have the correct shape for the known boundary conditions at the keel and deck edges; and the torsional responses indicated that the bow and stern sections and machinery box offered considerable warping restraint. A finite element analysis of the model and ship midship sections indicated that nearly the same torsional response was observed for each.
