Optimisation of Main Suspension Parameters of Four-Axle Bogie for Railway Crane
By comparing the various technologies of the existing railway lifting bogies in China,this paper introduces a new type of welded railway crane bogie,describes the basic structure and key parameters,and uses SIMPACK multibody dynamics simulation and analysis software to establish a railway crane dynamics calculation model,study the damping coefficient of shock absorber and the influence of axlebox tie rod positioning stiffness on vehicle dynamic performance,and provide a theoretical basis for the selection of bogie suspension parameters.
