摘　　要：建立了考虑测试基准倾斜时加速度计的数学模型。用初始安装误差角辨识理论及算法，在一定范围内消除或减弱了测试基准倾斜对加速度计数学模型辨识精度的影响。该方法可以降低对测试设备地基和调平装置精度的要求，降低其测试和标定成本，提高测试工作效率。The mathematical model of an acceleromter on test datum tilt is given in this paper. With the identification theory and algorithm of installing- error angle , the influence of tilt on the accuracy of identification for accelerometers may be dimin- ished or reduced to a certain extent. Using this method , the need for the baes of the testing equipment and the accuracy of level adjustment may be lower and the cost for testing and demarcating accelerometers can be reduced and the testing efficiency can be raised.
