DYNAMICS OF BRIDGE ASSEMBLIES

A methodology is developed for making a dynamic analysis of a bridge assembly with the use of hybrid mathematical models. Obtained are the conditions of conjunction of the bearing structure and attached subsystems which take into account the length of the suspension section. The investigation gives consideration to the influence of the static stres-deformed state on the dynamic properties of the system. The optimum selection of the main design parameters of the bridge assembly served as a basis for minimizing the reaction of the system to the characteristic dynamic effects. This made it possible to reduce the level of vibration of tea-leaf harvesting devices and to provide for the required trajectory of their working membersAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
