ABSTRACT:
For the calibration of an electronic measurement system with sensors which are arranged in pairs on structural parts of an airplane undercarriage which are loaded transverse to the lengthwise direction and which give off measurement signals which correspond to the vertical displacement between two sensor attachment points which are staggered from each other in the lengthwise direction of the structural parts, the pair of sensors which form a measurement point in each case being arranged approximately in the horizontal central plane of the structural part at positions opposite each other on the outside, a method is proposed in which a separate scaling factor is determined for each sensor of the pair of sensors. For this purpose, the measurement signals and weights are preferably determined for at least two conditions of loading of the airplane which are as far apart as possible and, furthermore, in connection with at least two different torsional conditions of the loaded structural part.
