[0002] The priority of the Chinese patent application, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to the field of mechanical engineering testing technology, and in particular to a suspended permanent magnet levitation vehicle suspension frame permanent magnet and guide wheel assembly and its arrangement method. Background Technology

[0004] Suspended permanent magnet levitation vehicles, as a new type of maglev rail transit system, mainly rely on the repulsive force between the vehicle's onboard permanent magnets and the track's permanent magnets to support the suspended permanent magnet levitation vehicle.

[0005] However, when the lateral offset between the vehicle-mounted permanent magnet and the track permanent magnet has a strong nonlinear deflection force, the vehicle-mounted permanent magnet and the track permanent magnet cannot be stably aligned, which will lead to lateral instability in the suspended permanent magnet levitation vehicle.

[0006] Therefore, how to improve the lateral stability of permanent magnet levitation vehicles is a technical problem that urgently needs to be solved by those skilled in the art.

[0007] Summary of the Invention

[0008] The purpose of this invention is to provide a suspension frame, permanent magnets, and guide wheel assembly and arrangement method for a suspended permanent magnet levitation vehicle, thereby improving the lateral stability of the permanent magnet levitation vehicle.

[0010] Based on the dimensions of the vehicle-mounted permanent magnet and the track permanent magnet, calculate the levitation force and deflection force of the vehicle-mounted permanent magnet and the track permanent magnet relative to each other in lateral and vertical distances. The lateral and vertical distances are the relative lateral and vertical distances between the geometric centers of the vehicle-mounted permanent magnet and the track permanent magnet. The lateral direction refers to the direction tangent to the two track surfaces and perpendicular to the center of the track, and the vertical direction refers to the direction perpendicular to the track surface.

[0011] When the levitation force is greater than the load-bearing weight and the vertical distance between the vehicle-mounted permanent magnet and the track permanent magnet is not less than the set levitation gap, the deflection angle of the vehicle-mounted permanent magnet is calculated based on the load-bearing weight and levitation gap of the suspended permanent magnet levitation vehicle.

[0013] Determine whether the difference between the support reaction force of the upper guide wheel and the support reaction force of the lower guide wheel is less than a preset multiple; if not, return to readjust the relative heights of the upper and lower guide wheels with respect to the vehicle-mounted permanent magnet and recalculate the support reaction forces of the upper and lower guide wheels.

[0014] If so, adjust the height of the guide wheel and the on-board permanent magnet, as well as the stiffness and damping of the guide wheel, and perform a vehicle system dynamics simulation analysis.

[0015] The system determines whether the offset attitude of the suspension frame, the lateral movement of the onboard permanent magnet, and the force on the guide wheel are optimal based on the vehicle dynamics simulation. If so, the process ends; otherwise, it returns to readjust the height of the guide wheel and the onboard permanent magnet, as well as the stiffness and damping of the guide wheel, and performs a vehicle system dynamics simulation analysis.

[0049] The core of this invention is to provide a suspension frame, permanent magnets, and guide wheel assembly and arrangement method for a suspended permanent magnet levitation vehicle, thereby improving the lateral stability of the permanent magnet levitation vehicle.

[0050] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0051] The method for arranging permanent magnets and guide wheels in a suspended permanent magnet levitation vehicle provided in this application includes the following steps:

[0052] Based on the dimensions of the onboard permanent magnet 2 and the track permanent magnet, the levitation force and deflection force of the relative lateral and vertical distances between the onboard permanent magnet 2 and the track permanent magnet are calculated. The dimensions of the onboard permanent magnet 2 and the track permanent magnet are initially preset. The lateral and vertical distances refer to the relative lateral and vertical distances between the geometric centers of the onboard permanent magnet 2 and the track permanent magnet, where lateral refers to the direction tangent to the two track surfaces and perpendicular to the track center, and vertical refers to the direction perpendicular to the track surface. Here, the lateral and vertical distances are coarsely adjusted.

[0053] When the levitation force is greater than the load-bearing weight and the vertical distance between the vehicle-mounted permanent magnet 2 and the track permanent magnet is not less than the set levitation gap, the deflection angle of the vehicle-mounted permanent magnet levitation vehicle is calculated based on the load-bearing weight and levitation gap of the suspended permanent magnet levitation vehicle.

[0057] If not, adjust the height of the guide wheel and the onboard permanent magnet 2, as well as the stiffness and damping of the guide wheel, and perform a vehicle system dynamics simulation analysis. At this point, adjust the height of the guide wheel and the onboard permanent magnet 2 to obtain the final height.
