Method of measuring buoyant center of underwater vehicle

The invention relates to the field of underwater vehicles, in particular to a method of measuring buoyant center of an underwater vehicle; the method comprises the specific steps of setting a certain point of the underwater vehicle as an origin to establish a three-dimensional model, with length direction as X axis, width direction Y axis and vertical direction Z axis, and measuring X-axis gravitational center, Z-axis gravitational center, X-axis gravitational center and Z-axis gravitational center. The method has simple principle, provides scientific calculation for measurement data based on the principle of moment balance, is widely applicable, and is not affected by mass distribution of an object. The method has high measuring precision; the buoyant center of an underwater vehicle can be measured precisely by the method, detection is facilitated, and efficiency is improved greatly for workers. 本发明涉及水下航行器领域，具体地说是种水下航行器浮心测量方法。具体是以水下航行器某点设为原点，建立三维立体模型，设长度方向X轴、宽度方向Y轴、竖直方向Z轴，测量包括X轴方向的重心测量、Z轴方向的重心测量、X轴方向的浮心测量和Z轴
