摘　　要：在分析两栖车出、入水原理的基础上,建立满足不沉性条件下两栖车出、入水数学模型。对Solid Works进行二次开发,形成不同出、入水角浮力大小与浮心位置的求解程序。通过实例分析计算得出两栖车满足不沉性条件时浮力、重力力矩与出、入水角的变化关系;并结合岸坡土壤条件,确定两栖车通过4种典型岸坡时的最大出水角和最大入水角。Based on the analysis of the principle of amphibious vehicle entering into and out of water, the mathematical model which meets the unsinkable requirement was established. After secondary development of SolidWorks, solving pro- grams for buoyancy and position of buoyancy centre with different angles of entrance and run were obtained. Verified with the example, the changing relationship between buoyancy torque, gravity torque, angle of entrance and angle of run was ob- tained after analysis and calculation. Through analysis of solid conditions of band slope, the maximum angle of entrance and angle of run when amphibious vehicle passes through 4 types of band slope were confirmed.
