MODELING OF DYNAMIC FILLING OF RING BRIDGES OF DUMPS ^{[№ 10 ' 2011]}
The authors researched frequency composition of voltage on the ring bridges of a dump truck and its relationship with the force in the sling and discovered resonant nature of variable voltage on the frame. Based on modal analysis of finite-elemental model car identified modal forms fluctuations in dump trucks and related forms of deformation of the frame were defined. The authors suggest ways to modernize the design to increase the resource. Methodology evaluation of durability of ring bridges based on modeling the dynamic filling at the stage of the project.
