    Abstract: A transport system comprising linear motor modules utilized both straight and curved track modules, with movers displaced on the track modules by control of power applied to coils of the modules. Curved track modules have modified spline geometries to provide desired acceleration and jerk characteristics. The modified spline geometries may be defined by more than one generators, such as an equation generator and a spline fit between the equation-generated segment and one or more constrained points or locations. The curved track modules may be divided into 180 degree modules, or may be reduced to 90 degree, 45 degree or other fractional arcs to provide for modular assembly, mirror-image geometries and motion profiles, and the like. The system may be adapted to provide improved motion characteristics based on modification of a conventional spline geometry.

  • Patent number: 9168950
    Abstract: A banked curve detection system determines the presence of a vehicle on a banked curve by sensing a vertical acceleration and a lateral acceleration of a vehicle. A banked curve is determined when the vertical acceleration and lateral acceleration are each greater than previously sensed vertical and lateral accelerations, the lateral acceleration is less than an expected reference lateral acceleration value, and the vertical acceleration is greater than gravity. The reference lateral acceleration value is based on yaw rate, steering angle, and wheel speed. When the acceleration conditions are met, the electronic stability control adjusts the parameters due to the vehicle being driven on a banked curve. Once the acceleration condition is no longer valid, the electronic stability control returns to normal operation.

  • Publication number: 20100126373
    Abstract: A method provides for the traction control of a maglev car on a maglev track. A levitation magnetic field is produced by supplying a levitation magnetic flux on the car side to at least two levitation magnets to produce a defined air gap between the maglev car and a reaction rail on the track side. A stator current is supplied to the stator to produce a propulsion force on the maglev track, the propulsion force acts upon the maglev car being determined by the magnetic coupling between the magnetic stator field and the magnetic levitation field. An oscillating movement of the maglev car in relation to the magnetic stator field is dampened by changing the magnetic coupling between the magnetic stator field and the magnetic levitation field on the car side. The levitation magnets are operated on the car side with at least two different individual levitation magnetic fluxes.

  • Patent number: 7640864
    Abstract: A non-magnetic concrete structure having no magnetism or a very small magnetic permeability without reinforcing steel bars arranged, a sidewall for a guideway, and a method for installing the sidewall for the guideway are provided. The reinforcing steel bars-free sidewall 11 for the guideway 10 is constructed by using a non-magnetic concrete structure constructed by using a fiber-reinforced cement-based mixed material and having no reinforcing steel bars therein. The fiber-reinforced cement-based mixed material is produced by mixing non-metallic fibers or non-magnetic metal fibers into a cement-based matrix in a mixing amount of 1 to 4% for an entire volume of the cement-based matrix. The cement-based matrix is obtained by mixing a composition with water. The above composition is composed of cement, aggregate grains having a maximum grain diameter of not more than 2.5 mm, pozzolanic reaction particles having particle diameters of not more than 15 ?m and supper plasticizer.

  • Publication number: 20090249973
    Abstract: A networked guideway transit system uses permanent magnet repulsion with induction-based repulsion within the networked guideway transport system, which can levitate passively with motion. Magnetic levitation technology is used to replace wheels as the primary means of vehicle suspension. The networked guideway transit system uses the permanent magnets to provide primary lift and uses electrodynamic repulsion to create centering forces at most operational speeds while integrating linear motor functions with the electrodynamic centering function. Further, the networked guideway transit system uses no moving parts in the guideways, which enhances reliability in the guideways.

  • Patent number: 7448327
    Abstract: Magnetic levitation methods and apparatus use arrays of vehicle magnets to provide three forces: suspension, guidance and propulsion. The magnets, which can be permanent magnets or superconducting magnets operating in the persistent current mode, have associated control coils that allow the magnets to provide a controllable attractive force to a laminated steel rail. The control coils adjust the gap between the magnets and the rails so as to be in stable equilibrium without requiring significant power dissipation in the control coils. These same magnets and steel rails also provide lateral guidance to keep the vehicle on the track and steer the vehicle on turns. The suspension control coils can provide lateral damping by means of offset magnets in the suspension arrays. Windings in transverse slots in the steel rails are excited with currents that react against the field produced by the vehicle magnets to create vehicle propulsion.
