摘要
通过对某厂房模型针对不同的测压管路系统在边界层流场中进行同步测压试验,对修正后的风压系数时程与目标时程进行对比分析,验证修正方法的可靠性。研究结果表明,采用风压测试技术可以获得较为准确的风压系数时程,经修正的实验结果可以用于工程实践。
A plant model with different tubing system was tested in the boundary layer flow field, the modified wind pressure coefficient time histories were compared with the target time histories to validate the reliability of the correction method. Research results show that accurate wind pressure coefficient time histories can be obtained by using the pressure testing technology offered in this paper, and the revised experimental results can be used for engineering practice.
