The track vertical geometric irregularity is considered as the excitation source of the vertical vibration of the system, and the hunting wave of car bogie frame is taken as the excitation source of lateral vibration of the system.
New designs of non-conventional bogies led us to develop a new model for independent wheels in which each wheel/rail contact must be treated separately due to the absence of an axle between left and right wheels.
The possibility of a prognostic estimation of the body's functional state based on comparative analysis of biological age measured by physical work ability parameters in truck drivers was considered.
The track vertical geometric irregularity is considered as the excitation source of the vertical vibration of the system, and the hunting wave of car bogie frame is taken as the excitation source of lateral vibration of the system.
This paper reports the formulation and presents numerical examples of a single wheelset contained within a bogie frame subjected to longitudinal forces of varying severity.
