TEST BENCH FOR TESTING ARTICLES BY COMBINED EFFECTS OF VIBRATION AND LINEAR ACCELERATIONS

摘要

FIELD: physics. ^ SUBSTANCE: proposed test bench comprises base to support vibrator with moving coil, driven rotor to connect vibrator moving coil with test table supporting counterweight and tested article, and radial and thrust bearings arranged on rotor. Vibrator moving coil incorporates axle to support rotor with test table to allow said axle to interact with thrust and radial bearings. Note here that thrust ring is arranged between thrust bearings to secure rotor to axial force exceeding vibration loads. ^ EFFECT: higher accuracy and reliability in simulation of linear and vibration loads. ^ 1 dwg
