针对目前试飞振动传感器校准效率低、随机误差大的现状,提出研发一套振动参数自动校准系统。通过控制振动台系统和采集记录设备,在线监测振动参数波形并现场处理校线。通过使用最小均方控制算法(LMS)算法实现对振动台系统的控制,再遵循IRIG106标准中对接口和指令的定义实现对机载采集记录器的控制,提取校准通道数据,再进行校准、校线显示及数据处理。本系统使用C++builder6.0编程实现,经验证,精度和效率均得到提高。
Aiming at the current situation of low calibration efficiency and large random error of test vibration sensor, a set of automatic calibration system of vibration parameters is proposed. By controlling the shaker system and acquisition and recording equipment, online monitoring of vibration waveform parameters and on-site processing of calibration. Through the use of minimum mean square control algorithm (LMS) algorithm to achieve control of the shaker system, and then follow the IRIG106 standard definition of interfaces and instructions to achieve on-board acquisition recorder control, extraction of calibration channel data, and then calibration Line display and data processing. The system uses C + + builder6.0 programming, verified, accuracy and efficiency are improved.
