直升机飞行载荷测量数据分析软件的控件开发

Control Exploitation of Analyzing Measured Helicopter Flight Load Measured Data

实测载荷是直升机疲劳设计与评定的关键数据。由于直升机实测载荷具有通道多、频率高、数据量大等特点,如何实现对实测数据高效快速处理显得十分关键。本文提出了一种用于直升机飞行载荷测量数据分析软件的控件程序开发技术,包含二维曲线及三维瀑布图控件,适用于大数据量的显示分析,可实现多条二维曲线并列显示及数据点的游标读取,不同视角的三维瀑布图旋转,具有易用,高效等特点。

Flight test measured load is the key data for fatigue design and evaluation, because the helicopter measured data has many channels, high frequency and large quantities. It is very important of how to deal with the measured data efficiently and quickly. This paper gave a control program development technology used to analyze the helicopter flight load measured data, including the two-dimensional curve and three-dimensional waterfall chart controls. It was applied to display and analyze large data. It could realize the function of showing multiple two- dimensional curves side by side, reading cursor data points and rotating the three-dimensional waterfall charts in different visual angles. It is useful and high efficiency.
