The purpose of this work is working out of the simulation system of the spatial motion of a HSGT on the straight and curvilinear sections of a railway. The simulation system is used for the computational investigation of a HSGT's dynamics and dynamic loading. A theoretical work with using of a modern mathematical approaches for the creation of symmetrical mathematical models which oriented for maximum computers - based suitability were conducted. The matrix mathematical model of the spatial motion of an asymmetrical rigid bodies system which consists of a system of Euler - LaGrange's differential equations of motion for quasi-speeds and kinematics equations with Rodrig - Hamilton's parameters is built on the ground of dynamic schema which is untraditional for vehicle motion dynamics. The model is symmetrical and adapted for modernization, transformation and algorithmization. Elastic links between different parts of HSGT and aerodynamic forces which applied on each element are taken into account. The software for numerical researches of the HSGT vehicle dynamics and dynamic loading on the straight and curvilinear sections of a railway is elaborated on the ground of the symmetrical mathematical models. The simulation system of spatial motion can be used for the dynamic design of new models of high speed railway machinery and study of existing one.
