  1. Besides to control rotate speed of electromotor, the control system adjusts wind speed, substantively it is the control of speed press ( v2 = 2q / p ). so, flow field control system adjusts speed press through the control of rotate of electromotor

    風洞流場控制系統除對電動機轉速調節外，主要控制風速v ，實質上就是控制其速壓q （ v ~ 2 = 2q p ） ，所以，風洞流場控制系統是通過控制電動機轉速，來調節實驗段內的速壓。
  2. Then figure out the wind load in term of the load criterion and the wind tunnel test results separately. by comparing with the two results, we can draw a conclusion that the values which generated by the load criterion are bigger than these ones generated by the other. in order to calculate and design in the worst situation, the paper select the bigger basic wind stress and then turn the area - load into liner - load to receive the displacement of the nodes and the internal force of the cells generated by the static wind load

    由此，得出用於作業棚結構設計的數據，進而按建築荷載規范和風洞試驗數據分別計算出風荷載標準值以及基本風壓，通過對兩種靜力風荷載計算的結果進行比較，可以看出，按規范計算風荷載的結果在結構的整體計算中偏於保守。按照最不利情況計算的設計準則，本論文選用較大的基本風壓值按受力面積分配的方法把面荷載轉化為線荷載代入midas運算程序中，求得該結構在該靜力風荷載作用下的節點最值位移。
  3.

  4. Designed a program which can use the mean pressure coefficient of jin ’ ao mansion to calculate mean wind load of the whole buildings and local floor. the integral result can apply into the practical design of construction, also can compare with the results of wind tunnel balance test to validate the veracity of this test

    通過自編的程序對金奧大廈表面時均風壓系數進行積分計算獲得其整體和局部樓層的平均風荷載，積分計算的結果一方面可以方便地運用於實際的建築結構設計中，另一方面可以與風洞天平測力結果進行比較驗證動態測壓試驗的正確性。
  5. Abstract : wind tunnel experiments were carried out to investigate the influence of wind direction on the wind pressure of proximite buildings. mean and fluctuating pressure coefficients on a high building, at sixteen different wind incidences and with one and two interfering buildings, were measured in the tests. this paper presents the characteristics of wind pressure on the building, which varies with the incident wind angle and with the numbers of adjacent buildins. due to the variation of wind angle and the interference effects, the complex feature of pressure distributions can be found on the downstream building surfaces for building group arrangement at certain angle of wind attack. some area of the interfered building for such configuration, in comparison with one single building ' s, may undergo very strong positive or negative pressures

    文摘:通過風洞實驗研究了風向對兩個和三個鄰近建築風壓分佈的影響特性.實驗結果給出了在不同風向角下，作用於受擾建築上的平均和脈動風壓系數.當受擾建築處于下游位置時，建築之間的干擾效應主要表現為遮擋影響，建築物上的總體風壓系數不是很大，但在建築物表面上有時會產生局部較大的負壓系數.另外，在某些風向角下由於受到上游分離氣流的影響，在下游建築的局部表面又會出現較大正壓.這些結果可供建築布置和結構設計時參考
  6.
