摘要:

对传统舰载机的系留计算模型进行了改进:在系留计算模型中不仅考虑系留索的弹性变形,还考虑舰载机轮胎的压缩变形;把系留计算的位移状态由平面的3个自由度增加到空间6个自由度;利用船纵横摇和升沉加速度的周期、峰值等参数形成的余弦曲线作为各船运动参数的输入形式。通过二维模型分析和实际模型计算表明,上述模型的改进在结果上增加了系留索的计算载荷,提高了系留计算的准确度,这对提高舰载机的机体强度,减轻舰载机的结构重量和改进系留设备的受力情况提供了更可靠的计算依据。

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.
