METHOD OF MODELLING ACOUSTIC LOADING OF STRUCTURE UNDER TEST FOR FATIGUE

摘要

FIELD: testing equipment. SUBSTANCE: method consists in reconstruction of preset spectral density of sound pressure under acoustically rigid wall installed in channel of driving wave, in measurement of characteristics of check parameter in which capacity sound pressure in measurement section or movement of mobile valve of electropneumatic sound generator is taken and in reconstruction of measured characteristics of check parameter of tested structure installed in channel of travelling wave. EFFECT: increased authenticity of fatigue testing. 2 cl, 5 dwg
