摘要
针对量程小于±1g的加速度计,提出了小角度十二点翻滚测试法来标定加速度计的模型方程。分析了小角度翻滚测试的原理,给出了模型系数计算公式,并利用该公式进行了理论仿真研究和实际测试,该测试方法得出的偏值K_0、标度因数K_1和输入轴安装误差角δ_o的值与国军标测出系数值的误差分别为0.36‰、0.09‰和3.24‰,其余模型参数也有较高的可信度,验证了小角度十二点翻滚测试方法的可行性。
In this paper,a new 12-point tumble test method was proposed for the pendulous accelerometer whose input range was too narrow to reach ±1g. The theory of the tumble test in a small angle was described,and the formula to calculate its model coefficients was presented. Based on the formula,the simulation and the test data were given,and compared with the GJB,the error values of the offset K_0, scale factor K_1 and misalignment angle δ_o were 0. 36 ‰,0. 09 ‰ and 3. 24‰,which validated this new 12-point tumble test method was feasible.
