针对惯性平台基于带回转台离心机导航精度试验的需求,定义了相关坐标系及其转换关系,给出了根据离心机运转参数计算载体相对惯性系的位置、绝对速度公式,推导了惯性平台加表和角度输出模型,建立了离心运动模型。最后,设计了长时间交替过载的离心机运动轨迹,并通过数学仿真对建模的正确性进行了验证,实现了惯性平台在离心机上运动过程的模拟,可用于开展基于离心机导航精度试验的仿真分析。
Based on the requirements of the inertial platform for precision test of the centrifuge with rotary table, the related coordinate system and its conversion relation are defined. The position and absolute velocity formula of the relative inertial system of the carrier are calculated according to the operating parameters of the centrifuge. Table and angle output model, the establishment of a centrifugal model. Finally, the centrifuge motion trajectory designed for long-time alternation overload was designed, and the correctness of the model was verified through mathematical simulation. The simulation of inertial platform motion on the centrifuge was realized, which could be used to carry out centrifuge-based navigation precision test Simulation analysis.
