| Summary: | According to the characteristics of the distributed force generated by the suspension electromagnet, the maglev vehicle vertical dynamic model whose suspension force generated by single electromagnet coil was simulated by multi-force elements was established. The maglev vehicle dynamic models was established by SIMPACK software which suspension forces generated by single electromagnet coil was simulated by single force element and three force elements and five force elements respectively. The difference between the actual levitation force and the levitation force simulated by multi-force elements was analyzed and compared. The simulation calculation was carried out under the excitation of track irregularity of different wavelengths. The influence of track vertical irregularities excitation of different wavelengths on the dynamics index of the maglev vehicle system was analyzed. The law of the dynamic response of the maglev vehicle to the different wavelength vertical excitation was obtained. The limitation of dynamic simulation of maglev vehicle dynamic model which suspension force was simulated by single force element with short-wave excitation was proved. |
