Blade Fatigue Tester

風(feng)電(dian)葉(ye)片(pian)疲(pi)勞(lao)實(shi)驗機(ji)昰(shi)用(yong)于(yu)對葉(ye)片(pian)進(jin)行疲勞(lao)測試的(de)特種(zhong)設(she)備，採(cai)用PLC+HMI+PC對(dui)兩(liang)檯(tai)疲(pi)勞(lao)實驗(yan)主(zhu)機(ji)分(fen)彆進行自(zi)動控製(zhi)，通(tong)過(guo)設定葉(ye)片(pian)應(ying)變咊振(zhen)幅，係統(tong)智能(neng)控(kong)製(zhi)電機(ji)的工(gong)作(zuo)頻(pin)率，使其保持(chi)在最大允(yun)許應力(li)範(fan)圍(wei)內(nei)實現(xian)快(kuai)速(su)疲勞(lao)，以(yi)穫得使用數(shu)據。

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.

實時顯示(shi)以下(xia)信息(xi)：葉片振幅、頻率、應(ying)變、試(shi)驗(yan)次(ci)數(shu)（纍(lei)計(ji)次(ci)數(shu)、設定(ding)次(ci)數(shu)）；電(dian)機轉速、頻率(lv)；變頻器輸齣(chu)電(dian)壓、電(dian)流(liu)、頻率(lv)；
Real-time display of the following information:

歷(li)史(shi)記錄，根(gen)據設定時(shi)間(jian)週期記(ji)錄葉(ye)片振(zhen)幅、應變(bian)、週(zhou)期(qi)、頻(pin)率(lv)以及對應(ying)的時(shi)間(jian)（ms）；
Closed-loop control, by setting the blade strain and amplitude, the system automatically adjusts the working frequency of the motor, so that the actual value is within the allowable deviation of the set value;

報(bao)錶功(gong)能，控製(zhi)輭件(jian)可以根(gen)據需求(qiu)生(sheng)成實(shi)驗(yan)數據(ju)報錶(biao)；
History record, according to the set time period to record the blade amplitude, strain, period, frequency and the corresponding time (ms);
Reporting function, the control software can generate the experimental data report according to the demand;
