摘要
基于直升机试飞数据,采用回归预测方法建立了振动预测模型。实现振动预测,提高了对飞行过程中振动情况的预知能力,可以有效地降低试飞风险。将预测结果与试飞结果进行对比,对异常数据的信号特征进行提取,还可以实现直升机振动故障的快速分析与定位。
Based on the test flight data of helicopter,the vibration prediction model is established using regression prediction method.Vibration prediction can improve ability to predict vibration and reduce risk during flight.By comparing the predicted results with the test flight results,the signal characteristics of abnormal data can be extracted,and the helicopter vibration faults can also be analyzed and located rapidly.
