| 仿真模拟试验器校准频闪灯传统校准方法需要操作者目视判断，试验结果的重复性较差，且存在评定所得不确定度较大的问题。为此，研究了航空专用测试设备直升机旋翼锥体频闪灯的一种实验室校准方法。该方法采用脉冲频率法以光电转换形式建立校准装置，对频闪灯的闪烁频率等技术参数进行校准。实验结果表明：在准确度大幅提高的同时，不确定度更小。与传统方法相较而言，本方法操作简单快捷，通用的标准设备即可满足校准要求，量值溯源更可靠、更容易，同时也符合计量相关法规的要求，具有一定的推广及应用价值。 |
| 英文摘要: |
| The traditional method for calibrating strobe using simulation testers requires visual judgment by operators, resulting in poor repeatability of test results and large uncertainty in the evaluation results. A laboratory calibration method for helicopter rotor cone strobe, a specialized aviation testing equipment, was studied. This method uses the pulse frequency method to establish a calibration device in the form of photoelectric conversion to calibrate technical parameters such as the flashing frequency of the strobe. The experimental results show that while the accuracy has been significantly improved, and the uncertainty is smaller. Compared with the traditional method, this method is simple and fast to operate, and universal standard equipment can meet the calibration requirements. The traceability of measurement values is more reliable and easier, and it also meets the requirements of metrology regulations, and has certain popularization and application value. |
