It is analyzed for the load condition between vehicle and track beam in over seat single track transit systems under wind load . Then, the equilibrium equations of the vehicle and the deformation equations of compatibility between vehicle and track beams are formed. Furthermore, according to above mentioned equations, the deformation and internal force of pressure wheel and equilibrium wheel(all together called oriented wheel) are studied under above wind load. Finally, designed the program and computed the deformation and internal force of vehicle and track beams while flexibility coefficient of oriented wheel varied. Lastly the relation charts of flexibility coefficient, internal force of oriented wheel, tilting angle of vehicle and horizontal transversal displacement are drafted respectively.
