THE EXPERIMENTAL MEASUREMENT OF SHIP MODEL BENDING MOMENTS IN WAVES

A comparative evaluation of three different methods of measuring ship model bending moment in waves is presented. The methods examined are (1) Semiconductor strain gages bonded into the shell of a fiberglass mode. (2) A segmented model with semiconductor strain gages bonded to a metal flexural element, and (3) a segmented model with relative displacement of the model sections measures by a linear variable differential transformer. The design of a bending moment dynamometer combining methods (2) and (3) is described and comparison of the three methods is made on the basis of operational experience and computations by linear strip theory.
