                     Evaluation of Chassis Frame Strength Using Actual Working Waveform Simulation   Actual Working Load Chassis Testing System


                    Load testing and fatigue testing on the chassis frame at the base of train cars are   Handrail  Control panel
                    performed. The load occurs as a result of the hydraulic actuator, and load amplitude
                    and frequency can be controlled by computer. The system, which can be loaded via
                    two vertical and four horizontal axes, can simulate the actual working waveform for
                                                                                              Horizontal frame

                    Chassis frame testing can be performed with the wheels and axle springs still
