摘　　要：首先，介绍了用加速度计代替陀螺作为惯性测量装置的优势，并介绍了无陀螺测量技术的发展状况。根据实际情况，给出了一种加速度计的配置方式，推导其输出公式。用分度头对各个加速度计进行标定，数据处理后，得到加速度计的灵敏度和零偏。用离心机做转速实验，得到的角速度曲线与设定的相一致，验证了方案的可行性。First, the advantage of accelerometers instead of gyro to be the inertial measurement unit is introduced, and the development status of gyro-free measurement technology is presented. A configuration with accelerometers and gyro-free is given out according to the application and the output formula is also derived. Handling the calibration data gained by the dividing head is to get the sensitivity and bias of all the accelerometers. Centrifugal experiment, and the corresponding ,angular velocity is gotten to justify the scheme.
