BED TESTING LARGE-SIZED ARTICLES FOR REPEATED IMPACT LOADS Russian patent published in 2000 - IPC

FIELD: testing equipment, test of resistance of articles to repeated impact loads under laboratory conditions. SUBSTANCE: bed testing large-sized articles for repeated impact loads is manufactured in the form of number of impact modules connected by common shaft. Number of modules is two as minimum and they are placed one relative to another at distance equal to distance between supports of article during its transportation. Each impact module comes in the form of bed frame, table to anchor article, former of impact pulse coupled to drive of mechanism for lifting and shedding of table made of shaft carrying cams of pusher. Common shaft is sectional over its length and is made of separate links fitted with cams whose number equals number of impact modules. Cams are mounted on shaft for turn with regard to each other through circumference. EFFECT: approximation of conditions of bed testing of large- sized articles to actual conditions of loading thanks to formation of impact loads changing over length of article, reduced usage of metal for manufacture of bed. 7 dwg
