摘要：

An experimental apparatus to measure added mass and damping coefficients in pure heave or pitch or the coupling coefficients in combined motion on a surface effect ship (SES) sidewall with a forward speed in the small test section of a hydrodynamic water tunnel has been built. To check the results obtained, the whole experimental set has been modified to be used in a towing tank with a 3.3 larger model with same values of reduced parameters. Comparison with both kinds of measurements is satisfactory. The influence of Froude number, amplitude of motion, frequency and phase lag between motions for combined motion has been studied; some tests have been also performed with two symmetrical sidewalls (catamaran). Measured coefficients have been compared with computed ones obtained with the code AQUA + from the ECN. In spite of the large motion amplitudes, agreement between tests and linear computations is quite acceptable.
