惯性器件多参数测试设备校准技术关键问题

Key Problems of Calibrating Multi-parameter Testing Equipment for Inertial Devices

多参数测试设备的高精度校准对提升惯性器件实战性能有重要影响。通过归纳分析现有多参数测试设备的计量标准,指出分立校准的环境条件与多参数测试设备的使用条件不一致,校准结果适用性有限。建议研制适用于多参数复合环境的传递标准,开展多通道异步数据的同步采集与动态校准技术和多参数测试设备可计量性设计等研究,形成与多参数测试配套的计量技术体系,提升惯性器件多参数测试设备的校准能力。

High-precision calibration of multi-parameter testing equipment plays an important role in improving the performance of inertial devices in practical conditions.By introducing latest developments of calibration standards for multi-parameter testing equipment,the shortcoming of isolated calibration that caused by the difference between the isolated calibration environment and the composite condition produced by the multi-parameter testing equipment is analyzed.To solve the problem and improve the capability of calibrating multi-parameter testing equipment,it is suggested to develop transmission standards suitable for multi-parameter composite environment,carry out research on synchronous acquisition and dynamic calibration technology of multi-channel asynchronous data,and carry out research on metrological design of multi-parameter test equipment to form a metrological technology system supporting multi-parameter test.
