light rail vehicle is modeled as a 2 d. o. f linear system for the design of vertical suspension characteristics and a 4 d. o. f. linear system for the design of lateral suspension characteristics. FRA's class-5-track irregularity is used for the exciting disturbance on track. Suspension stiffness and damping is selected on the basis of the ride quality and suspension stroke trade-off for the bogie of light rail vehicle. The optimum value of primary and secondary suspension characteristics is determined. And the stability of full vehicle model for the LRV is analyzed using the VAMPIRE program and critical speed is determined.
