摘要
以用于测斜仪的三轴转台为研究背景,通过分析其运动规律,探讨了三轴转台不正交度误差源对三轴转台精度的影响,并用MATLAB对它进行了误差建模,仿真计算得出了系统装配不正交时三个坐标的误差率;最后,引入实际测试过程中角度传感器的测量误差,在三轴不正交的前提下又对三坐标测量误差进行了数学建模,通过仿真分析,研究探讨了角度传感器带来的误差规律,在实际应用中为测斜仪标定测试和误差补偿提供了理论依据。
Through analyzing the inclinometer's three-axis turntable motion principle,this paper discusses the influence on the accuracy of three-axis turntable which is generated by the error source of three-axis nonorthogonality.And we build systematic error modeling as well as obtain three coordination's error rate by simulating calculation.At last,by introducing actual angular transducer measuring error,we achieve a mathematical modeling on the premise of three-axis nonorthogonality.The research studies the angular transducer error pattern by simulation analysis,thus it provides theoretical foundation for inclinometer test and error compensation.
