Fig. 7 Simulated behavior of the inertial gup control length, and when the control error exceeds specific limits, the reference input can be switched. The curves depicted in Fig. 7 are the results of a simulation. A sinusoidal 5 Hz oscillation was applied to simulate the periodic disturbances of the track, and at time t, an additional ramp disturbance was superimposed. The positive characteristics of the inertial control not only determine the energetic behavior of the magnet but also...

Two comments can be made about the results presented in Table VI. First, the major weakness of the component buildup method is the uncertainty in the bogie and the bogie guideway interaction drag. It is also the largest of the three components. Second, the uncertainties of the results based on 2 and 3 are unknown and hence a comparison cannot be used to vahdate the component buildup method. drag of Maglev vehicles. It includes procedures, commonly used in subsonic aircraft studies, to estimate...

Assuming a pole pitch of 2 m for the SCM and a vehicle speed of 138 m s, one obtains vcl 13.9 m s and vc2 16.1 m s. The time constant of the coil is about 42.6 ms. Figure 6 shows the dependence of the null-flux lift force components on the vertical displacement with a lateral shift of -5 cm and an effective air gap of 20 cm. One can see that the lift forces Fzll and Fz22 are dominant, and Fz 2 and Fz2j, resulting from the cross-connection, are relatively small. It should be noted that Fzi l is...

spoiled by a fire on last October 3rd in 1991. Using a new car named MLU002N which has two aerodynamic braking sets, test runs on Miyazaki test track have been resumed in Jan. '93. Up to the present, we have developed a simpler I-type SCM a lighter concentrated arrangement of SCM using a truck a downsize onboard refrigerator to re-liquefy the evaporated helium gas a track brake system with sliding frictional shoes for high speed running an aerodynamic brake and so on. Now, using MLU002N, we are...
