Abstract

The invention discloses a sine wave waveform combined compensation method for an arresting impact test, which is characterized by comprising the steps of 1, adding a half-sine wave in front of an original arresting impact waveform to perform speed compensation so as to enable the acceleration amplitude and the table top displacement to be the minimum; 2, adding a complete sine wave in front of thecompensated waveform to perform displacement compensation so as to enable the speed and the acceleration of the table top of the vibration table to be both 0; and 3, carrying out a test according tothe combined waveform after two times of compensation. According to the invention, an arresting impact test can be carried out on part of vibration tables whose speed and displacement do not meet testconditions.

Description

technical field

[0001] The invention relates to a sine wave waveform combination compensating method for arresting impact test, which can make the arresting impact test be carried out on a vibrating table whose partial speed and displacement do not meet the test conditions. Background technique

[0002] The product needs to be able to work normally under the overload of itself and the external environment, which requires the product to be verified by testing equipment in the laboratory. The arresting landing process is completely different from the landing approach of ordinary aircraft. The aircraft must land on the calibrated glide path, and the aircraft must be decelerated and braked in a short distance by the landing brake arresting cable. The impact load at the moment of the arresting landing and the forced braking load of the arresting cable are quite different from those of the ordinary landing, but the test value during the arresting landing process is higher, the dur...
