摘要
摇荡是两栖车辆在海上使用中存在的重要问题,它直接影响着乘员和装备的战斗力发挥。基于船舶的耐波性理论对两栖车辆在波浪中的线性摇荡问题进行了描述,通过实验得出了两栖车辆及其行走机构在横摇、垂荡状况下的共振频率和无因次阻尼系数,并对两栖车辆在我国某海域的海浪情况下可能出现的3种典型摇荡问题进行了简单的计算分析。
The toss motion is a trouble for amphibious vehicle in sea-way. It may severely affect the battle effectiveness of crew in the vehicle. A linear toss motion in wave was described based on the wave resistance theory for ships in this paper. Resonance frequency and damping coefficients of vehicle and mechanism of suspension and propelling in roll and heave motions were obtained by experiment. Then, these coefficients are used to ana- lyze the possible toss motion of three typical vehicles in a sea area of our country.
