Dynamics analysis of new devices devel-opment for counteracting negative oscillations arising from the operation of a single-bucket excavator with a hydraulic hammer

open access: yesGіrnichі, budіvelnі, dorozhnі ta melіorativnі mashini, 2019
На сьогоднішній день зберігається тенденція використання землерийної техніки зі змінними робочими органами. З точки зору технології виконання робіт це має економічно доцільне обґрунтування [1]. Проте, якщо розглядати довговічність окремих вузлів машини, така експлуатація базової машини призводить до різкого зменшення її довговічності та погіршення ...
