Simulation Test Using Actual Working Waveforms






                     4830 Controller for Use in Fatigue/Endurance Testing


                    The system accurately recreates the working waveforms to which each   ˙ Generates highly reproducible load waveforms.
                    component is subjected when the train is actually running. The system restricts   ˙ Uniform load "push" test function, suitable for testing actual samples
                    excess functions and automatically specifies complex parameters, making it   ˙ Synchronous control of up to four actuators
                    possible for anyone to simply implement actual working waveform tests.
