| 摘 要： | 目前双断级滑行艇纵向运动稳定性的理论计算方法还不成熟，推荐一种校核其纵向运动稳定性的实用方法，即利用模型试验得到纵向运动时而稳定时而不稳定的临界点组合，再运用最小二乘法拟合试验中得到的若干临界点得出双断级滑行艇纵向运动稳定性界限。用通过模型试验得到的纵向运动稳定性界限校核高速双断级滑行艇纵向运动稳定性能够获得比较准确的结果

| Abstract: | At present, the theoretical method to compute the longitudinal motion stability of double- stepped planing boats is immature. Therefore, in this paper,a useful method to examine the longitudinal motion stability of such boats is recommended. First, the critical points corresponding to stable and un- stable longitudinal motions are collected from the model experiment. Then, these critical points are fitted by using the least square method so as to obtain the limit curve to evaluate the stability of such boat... |
