    Abstract
  • The longitudinal and vertical components of air gap magnetic field of linear induction motor(LIM) were solved by the two-dimensional electromagnetic field theory, and the analytical expressions of traction force and normal force of LIM were obtained. The analytical calculation method was tested by using the test bench for LIM, and the variations of traction force and normal force with speed under the constant slip frequency range of 6-18 Hz were compared. The dynamics model of a single maglev vehicle with three levitation frames was built. The vibration responses of car body and levitation frame under the impact forces of 1, 3, 5 and 8 kN were simulated and compared. The traction performance of a single middle-low speed maglev vehicle was calculated, the influence of slip frequency on the traction performance of vehicle was analyzed. Considering the influence of normal force on the levitation system and the traction demand of vehicle comprehensively, the variable slip frequency control(VSFC) strategy was proposed. Research result shows that the traction characteristic of LIM generally contains the constant force zone(CFZ) and constant power zone(CPZ). The primary current in the CFZ reaches a maximum of 390 A, and the voltage in the CPZ reaches a maximum of 212 V. The traction force in the CFZ changes little, and decreases rapidly in the CPZ. The smaller the slip frequency is, the greater the starting traction force and normal force of the motor are, and the shorter the CFZ is. When the normal impact force is less than 8 kN, the vehicle stability index grades are all excellent. However, in order to reduce the load of levitation system, the normal force of LIM should be as small as possible. The traction performance of vehicle in the low speed zone under lower slip frequency is better than that under higher slip frequency, but the higher slip frequency is beneficial to improve the traction performance in the full speed range. In the VSFC strategy, the selection of starting slip frequency takes into account the traction performance and levitation ability of vehicle, and the slip frequency gradually increases after the speed reaches the turning point of constant power. Under the VSFC strategy, the traction force is moderate in the CFZ, and is always the maximum value that the motor can exert in the CPZ.
