Study on Operation Stability of New Four Modules Middle-low Speed Maglev Vehicles on a Straight Track
The operation stability of new four modules middle-low speed air spring center-position maglev vehicle was simulated by using the SIMPACK. The simulation results showed that when the speed of maglev vehicle exceeded a certain critical speed on a straight track, the lateral instability of the suspens...

| description | The operation stability of new four modules middle-low speed air spring center-position maglev vehicle was simulated by using the SIMPACK. The simulation results showed that when the speed of maglev vehicle exceeded a certain critical speed on a straight track, the lateral instability of the suspension frames would occur. Further analysis revealed that the lateral instability of suspension frames was related to vehicle weight and track irregularities, but not to levitation control. After the ball joints were installed at the end of the adjacent suspension frames, the new four modules maglev vehicle could operate stably in low speed range (less than 130 km/h). Finally, not only the lateral shock absorbers were installed between the two ends of the suspension frames under the fixed sliding platforms and the vehicle body, but also the lateral shock absorbers were installed between the outer ends of the suspension frames under the sliding platforms and the vehicle body, so the maglev vehicle could operate stably in the whole speed range. |
