摘　　要：基于波动原理开展了T型测压管路系统频率响应特性的实验研究,并根据脉动风压现场实测的基本过程,分别给出了影响测压管路系统频响特性的3个主要因素,每个因素设置了4个水平,基于16个正交实验结果,通过显著性分析,找出了影响因素对测压管路系统频响特性的主次性。结果表明:输入端管路长度对T型测压管路系统频响函数的影响最大,接收端管路长度的影响次之,排水端管长度的变化对测压管路系统的影响最小。The dynamic frequency response characteristics of pressure measured by Tee- junction tube system were investigated by a dynamic pressure response experimental method based on the wave theory. Three main factors,each one being set to four varying levels based on 16 orthogonal experimental results,affecting the pressure measured tube system frequency response characteristics were given according to the basic process of fluctuating wind pressure field testing. Then the primary and secondary of length influencing factors were found out by significance analysis. The results showed that the primary and secondary sequence of parameters influencing the Tee- junction tube system frequency response function were in the order of the input tube length,the receiver tube length and the drainage tube length.
