| 摘 要： | 在惯性仪表主轴转台测试的基础上,采用四元数法建立了转动中的三轴转台数学模型,并以此计算在三轴转台转动中的各个时刻,重力加速度在惯性仪表坐标系上的投影,从而完成惯性仪表三轴转台测试中动态输出量和静态输出量的分离。该方法用代数运算代替了欧拉法中的三角运算,具有简单、精确且不会出现奇异的优点。在文章最后给出了在某一测试下的计算结果。

| Abstract: | Based on the inertial meter tested on three-axis turntable, a mathematical model of rotating three-axis turntable is established with the method of quaternion, also the project of gravity on inertial meter coordinate frame at any time in dynamic test is calculated and the dynamic output and static output in the test are separated. The method is simple and accurate uithout odd because it replaces triangle operation in Elder method with algebra operation. The calculated result in a certain test is given in the end. |
