摘要
基于船舶的耐波性理论,对两栖车在波浪中航行的摇荡问题进行了研究。选取5种两栖装甲车辆进行分析。通过试验和计算得到其横摇、纵摇及垂荡的固有周期和阻尼系数,进而对其3种摇荡的微分方程进行求解。通过计算结果,分析在不同蒲福风级下的3种典型摇荡,提出了所选取的5种车辆在波浪中航行时避免产生剧烈摇荡的方法及在使用中的可行性建议。
Based on the wave-resistance theory for ship, it studies the toss motion of amphibious vehicle in wave. Five kinds of amphibious vehicles were analyzed. Inherent periods and damping coefficients in latitudinal, longitudinal and vertical tosses were obtained from experiment and calculation. Further, three types of toss equations were solved. Based on those results, three types of typical toss motions under different Beaufort wind scales were analyzed, and the methods to avoid severe toss motion and feasible recommendations in use were put forward.
