The invention discloses a method,
system and device for measuring
surface pressure of a wing, and the method comprises the following steps of the first step, dividing the wing into a plurality of wingblocks by a block division strategy, so that there is no gradient in the
surface pressure between each point in each wing block; the second step, obtaining the position of a
strain measurement pointon the wing based on the finite
element model and the block strategy; the third step, installing a
strain measurement component at the position of the
strain measurement point on the wing to perform the strain measurement; and the fourth step, obtaining the pressure of each wing block on the wing according to the measured strain data, that is, obtaining a pressure distribution value on the wing. By dividing the wing into a plurality of wing blocks by the block division strategy, obtaining the position of the strain
measurement point on the wing by using the finite
element model and its calculation results, and reversely calculating the actual pressure value of the wing during the work process by combining the measurement of the actual strain of the strain
measurement point on the wing, theprecision of the
surface pressure obtained of the wing is high, the implementation method is convenient, the economy is high, and the efficiency is high.
