Intelligent control device and method for inlet attack angle of tornado test

Abstract

The invention discloses a tornado test inlet attack angle intelligent regulation and control device and method, and belongs to the field of structural wind engineering test equipment.The device comprises a main control computer, an attack angle regulation and control device, an inlet wind speed test module and a tornado simulator internal PIV module, the main control computer is wirelessly connected with the attack angle regulation and control device, the inlet wind speed test module and the internal PIV module of the tornado simulator to transmit data; the main control computer receives the internal wind field structure parameters of the tornado simulator provided by the PIV module in real time, analyzes the actual attack angle of the internal wind field based on a wind field characteristic parameter analysis algorithm, performs autonomous optimization analysis of the entrance attack angle through a machine learning optimization algorithm, and transmits the attack angle regulation and control quantity to the attack angle regulation and control device; therefore, accurate regulation and control of the inlet attack angle of the visual test tornado test are realized.

Description

technical field [0001] The invention relates to the field of structural wind engineering, in particular to a tornado test entrance angle of attack intelligent control device and method. Background technique [0002] Wind disaster is one of the most serious natural disasters in my country. Thousands of kilometers of continental coastline are exposed to the attack range of Pacific typhoons. In addition, my country has a vast territory and a complex and changeable meteorological environment. Tornadoes and downbursts often occur. wind disaster. Among them, tornadoes are the most violent convective storms in the earth's atmosphere. The maximum wind speed near the ground can reach 170m / s, and the destructive power is extremely strong. It often leads to the destruction or even collapse of a large number of engineering structures, resulting in heavy casualties and economic losses. In 2016, an EF4 tornado occurred in Funing County, Yancheng City, Jiangsu Province (the maximum gust wi...
