两栖车辆任意倾斜状态下浮心计算研究

为解决两栖车辆任意倾斜状态下浮心计算的难题,基于SolidWorks对两栖车辆进行三维建模,建立了惯性和非惯性2个坐标系描述浮心和倾斜状态;研究了横倾角、纵倾角与坐标变换的关系;在此基础上结合SolidWorks的API函数,采用向量运算确定了求解浮心位置的二分法及其迭代区间和车辆的入水部分。对SolidWorks进行二次开发,形成了任意倾斜状态下浮心求解程序,进一步将本程序运用于浮态计算。与传统方法相比,其计算速度快、结果精确,且不必对车辆外形进行简化。这为浮态设计和稳性分析提供了有效的手段。

Calculation of Amphibian Vehicle Buoyant Center in Arbitrary Inclining State

In order to resolve the problem of buoyant center calculation in arbitrary inclining state,3D modeling of amphibian vehicle was constructed by using SolidWorks.Both inertial and non-inertial coordinate systems were established to describe the buoyant center and inclining state of the amphibian vehicle.the relations of rolling and pitch angles with the coordinate transformation were studied.Using API functions in SolidWorks and vector operation,a bisection method and its iterative interval to find the buoyan...
