Description
Summary:The paper provides an analysis that shows application of pump-controlled steering hydraulic drives. Dynamic model of steering hydraulic drive of open-cast BelAZ-75131 dump truck developed at BNTU and also mathematical models for circuit consisting of a metering pump and a turning cylinder and a flow amplifier and a turning cylinder with due account of compressibility and resistance of service drain line. It is noted that on the basis of the given methodology a multi-variant dynamic calculation has been carried out, drive dynamics has been analyzed at various design and component parameters of a metering pump and a flow amplifier, rational values of these parameters has been selected for design development. The paper also gives an algorithm scheme for the solution of the derived equation systems.
