【摘要】 动态风荷载测试数据的可靠性依赖于大气边界层流场的正确模拟。本文根据作者在FD-4大气边界层风洞中,进行大气边界层流场调试时,就如何准确模拟自然风的四个参数方面所积累经验的总结。事实表明,除了必须调整粗糙元等阻力元件的放置方式外,还必须认真注意信号的采集,FFT的准确调用以及数据的前、后处理。更多还原

【Abstract】 The methods for modelling nature wind flow in boundary layer wind tunnel were discussed in this paper. The profile of time mean velocity and turbulence intensity, power spectrum density, and turbulence scale length should be simulated before the model testing. More attention should be paid in the data collecting and processing when the calibration of atmosphere boundary layer flow field was conducted .更多还原
