Abstract: There are many channels and parameters in helicopter static test and fatigue test, using the traditional manual calibration creates heavy workload and low efficiency as well as overtime calibration cycle. Utilizing the communication interface of standard equipment and based on the VEE Pro software exploit platform, a platform of the automatic calibration was designed for the test load control and data acquisition system. The platform contains three main modules: Equipment Information Collection Module; Servo Control Channel Calibration Modules; Data Acquisition Channel Calibration Module and Printout Module. Practices showed that the platform is reliable, effective and accurate. The platform played an important role in all kinds of helicopter experiments, and it can be applied widely.
