In view of high-speed working characteristics of four-bar beating-up system. the simulation study was carried out under the influence of joint clearance and beating-up resistance. The discontinuous contact model with two-state was applied to clearance modeling of crank bearing. A rigid flexible coupling model of double side four-bar beating-up system was set up by ADAMS/View which on ... https://www.bekindtopets.com/mega-grab-SDS3113-High-Tea-Single-6-top-grab/
