Abstract

The application discloses a rainfall implementation device, a parameter calibration method thereof and related equipment. A first control subunit calculates a rain intensity value according to the wind-driven rain test rainfall similarity criterion and a reduced-scale parameter after receiving the reduced-scale parameter of a wind tunnel test segment model or aeroelastic model and sends a first rainfall parameter corresponding to the rain intensity value to a rainfall system; the rainfall system simulates rainfall according to the first rainfall parameter; a test feedback system measures a second rainfall parameter when the rainfall system simulates rainfall, and feeds back the second rainfall parameter to a second control subunit system; the second control subunit calculates deviation according to the first rainfall parameter and the second rainfall parameter; and when the deviation is greater than a preset threshold value, updating the first rainfall parameter based on the deviation,and sending the updated first rainfall parameter to the rainfall system. Therefore, technical problems of unsatisfactory adjustment of the rainfall parameters, poor adjustability of a rainfall device and low automation degree of the existing structural wind area reduced-scale model are solved.

Description

technical field [0001] The present application relates to the technical field of wind engineering, in particular to a rainfall device, a parameter calibration method of the rainfall device, and related devices. Background technique [0002] The coupling effect of wind and rain is also known as the phenomenon of wind driving rain. Compared with the pure wind effect, the coupling effect of wind and rain may have a non-negligible impact on structural vibration. According to relevant accident data in the field of disaster prevention and mitigation of engineering structures, under the coupling effect of wind and rain, the amplitude of the stay cable can reach more than 1 meter, the maximum value of the displacement response of the transmission tower may increase by 15%, and the additional load of rain on the windward wall of the building The value may reach 30% of the pure wind load, which is extremely harmful to the safety of the structure. Therefore, it is urgent to quantify th...
