摘要
利用基于高精度的流体管道耗散模型所建立起来的传递矩阵方法分析了小管径测压管路的动态特性并做了试验对比 ,得到了非常满意的结果 ,同时用编写的程序对脉动风压测试中所采用的一些常用的加管路阻尼器的方法作了模拟计算分析 ,得到一些比较有用的结论 。
In the paper,an accurate fluid dissipation model is empl oyed to build up a matrix transfer procedure,which is used to analyze the dynam ic characteristic of tubing system with small diameters.The experimental measur ements are also carried out.The result shows that the theoretical predictions agree very well with the ex periments.Some useful conclusions are obtained by simulating the tubing systems,which are often used in fluc tuating wind pressu re measurements.With the method proposed,the dynamic characteristics of the tu bing sys tem can be predicted perfectly and the results can be used to eliminat e the signal distortion during the multi channel simultaneous measurements for fluctuating wind pressure.
