为进行动态测试系统的误差溯源研究,以一种差动互感电感式位移传感器动态测试系统为研究对象,分析各部分的动态测试特性,分别建立了各环节的单元传递函数与误差函数,并根据全系统动态测试精度理论,建立了该系统总的传递链函数及误差传递”白化”模型。
In order to study the error traceability of the dynamic test system, a kind of dynamic test system of the differential mutual inductance inductive displacement sensor is taken as the research object, the dynamic test characteristics of each part are analyzed, and the unit transfer function and the error function of each link are established respectively. System-wide dynamic test accuracy theory, established the system’s overall transfer chain function and error transfer “albino” model.
