摘要
建立了描述车辆姿态向量和重力向量的两个坐标系,研究了姿态向量与坐标变换之间的关系,根据Solid-Works提供的函数,利用二分法求解了给定姿态下的浮心位置;以浮心计算为基础,通过对车辆的受力分析和运动分析,确定了车辆浮态的计算方法;利用SolidWorks的API函数进行二次开发,形成了计算静稳性的程序,并进行了实例计算。结果表明：与传统的作图法相比较,该方法计算结果更精确,计算速度更快。
Firstly,two coordination systems are established to express the pose vector and gravity vector and the relation between pose vector and coordination transformation is studied.Bisection method is adopted to obtain the buoyancy center with Solidworks function.Secondly,the computation method of floating state is worked out based on the buoyancy center computation through the analysis of force and kinematics.Finally,the secondary development is designed through Solidworks＇ API function and hydrostatical stability performance solving program is finished and it is applied to a certain amphibian vehicle.Compared with the traditional method,the result of solving program is more accurate and its speed is faster.
