A UNIFIED DYNAMICAL ANALYSIS OF ANTISYMMETRIC SHIP RESPONSE TO WAVES

In an earlier paper dealing with symmetric response to waves it was shown how transfer functions could be calculated for a ship responding in sinusoidal waves. The present paper deals with the problem of antisymmetric response. Possession of the techniques outline in the two papers permits the calculation of general response to sinusoidal waves and hence makes the study of random seas possible. As in previous work the treatment rests on the concept of linearity. While this is unlikely to be a serious drawback for anything but the most violent motions and distortions, it does admit a substantial simplification of the theory. Indeed a general dynamic theory for antisymmetric responses that is not based on linearity is certain to be very difficult to formulate and is quite out of the realms of possibility at present. Despite this simplification, however, one or two areas are exposed in the present paper in which even linear theory appears to be deficient. One object of this paper, then, is to focus attention on certain topics in which further research would be particularly useful. Order from BSRA as No. 52,631.
