PROCESS TESTING ELASTIC SYSTEMS FOR VIBRATION STRENGTH Russian patent published in 1997 - IPC

FIELD: tests of shock-absorbing systems of instruments. SUBSTANCE: tested elastic system with concentrated inertial mass is subjected at points of its attachment to action of harmonic vibration with fixed frequency and constant acceleration of inertial mass. Lowest resonance frequency f_r of elastic system and acceleration j_m on inertial mass on frequency f_sp<f_r specified in service forms and records for article are determined in advance to set mode parameters of test. Test are conducted on frequency f_t chosen from relationship f_sp<f_t<f_p with acceleration on inertial mass equal to j_m.. Vibration strength of elastic system is evaluated by change of acceleration at point its attachment. EFFECT: simplified process of test for vibration strength. 2 cl
