Comfort and safety are the main factor while designing a new rolling stock, Comfort depends on the ability of vehicle suspension system to make good condition for passengers without make any fatigue or damage rolling stock. Comfort could mean that roiling stock could be operated at certain speed and certain track without make any vibration that could make fatigue or sickness. Comfort depends on suspension system, moment of inertia and mass of the vehicle it self.<p>Argo Class Trains use NT-60 bogie and CL-243 bogie. The CL-243 is bolster less bogie and uses rubber spring for its primary suspension and air spring for its secondary suspension. Compare with bogie that PT Kereta Api has, this bogie has damper for vertical rotation or usually called hunting motion.<p>This calculation purpose is to find bogie CL-243's performance with modeling and dynamic analysis in the view of vibration that is received by passengers. This calculation uses MSC/Nastran acid some calculation software for FFT such MathLab.<p>The result shows that higher value of rail stiffness, natural frequency much lower, From the exitation, there are vibrations that exceed fatique limit of ISO.
