Blade Fatigue Tester

风(feng)电(dian)叶片疲劳(lao)实(shi)验机是用于对叶(ye)片(pian)进行疲(pi)劳测试的(de)特种设(she)备(bei)，采(cai)用PLC+HMI+PC对(dui)两台(tai)疲(pi)劳实(shi)验(yan)主机分(fen)别进行(xing)自动(dong)控(kong)制，通(tong)过设(she)定(ding)叶片应(ying)变(bian)和(he)振(zhen)幅(fu)，系统(tong)智能(neng)控制电(dian)机(ji)的工作频率(lv)，使其(qi)保持(chi)在最(zui)大(da)允(yun)许应(ying)力范围(wei)内实现(xian)快(kuai)速疲劳，以获得使用数据。

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.

Real-time display of the following information: 
blade amplitude, frequency, strain, number of tests (cumulative number, set number); motor speed, frequency; inverter output voltage, current, frequency;

历(li)史(shi)记录(lu)，根(gen)据设定时(shi)间周(zhou)期(qi)记(ji)录(lu)叶(ye)片(pian)振幅、应变、周期(qi)、频(pin)率以及(ji)对应的(de)时(shi)间（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;

报(bao)表功能(neng)，控制(zhi)软(ruan)件可以根据(ju)需(xu)求生(sheng)成实(shi)验数据报(bao)表；
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;
