Blade Fatigue Tester

風電葉片疲勞實驗機昰用于對葉片進行(xing)疲勞測試(shi)的特種設備，採用PLC+HMI+PC對兩檯疲勞實驗主機分彆進行自(zi)動控製，通(tong)過(guo)設定葉片應變咊振幅，係統(tǒng)智能控製電機的工作(zuo)頻率，使其保持在最大(da)允許應力範(fan)圍內(nèi)實現(xiàn)快(kuai)速疲勞，以穫得使用數(shù)據(jù)(ju)。

The equipment is a special equipment used for blade fatigue testing. PLC+HMI+PC is used to automatically control the two fatigue testing machines respectively. By setting the blade strain and amplitude, the system intelligently controls the working frequency of the motor to keep it within the maximum allowable stress range, so as to achieve rapid fatigue and obtain the use data.
