Abstract:

This article provides an improvement to the conventional model of mooring computation for shipbased aircraft. First, the model of mooring computation not only takes into consideration the elastic deformation of the mooring cable, but also the compressed deformation of tyres. Second, the displacement state of the mooring computation model is extended from three degrees of freedom in a plane to six degrees of freedom in space. Third, the movement parameters of the mooring computation is based on the combination of three cosine curves, which are generated by the acceleration cycle and amplitude of the ship’s transverse and longitudinal swing as well as its ascent and descent. Analysis of a two dimensional mooring computation model and the computation of a particular example show three improvements of the mooring computation model: it can increase the force of the mooring cable and the accuracy of the computation; it can provide more reliable data to improve the structural strength of a shipbased aircraft and reduce its weight; and it also provides more reliable data to improve the force state of the mooring facility.
