Electric Power Steering system provides the assist steer torque in vehicle through an electric motor. Since the electric motor is directly connected to the mechanical steering rack, must have the following features: Torque production with minimum Ripple for Precise steer control, High efficiency, easy Manufacturing technology and minimum size and weight. Motor structure optimization is done in ...

metal forming processes, compared with machining ones, reduce production steps and increasemanufacturing speed in addition to saving raw material. in this paper, forming process of column ofa steering mechanism is investigated by finite element analyses and experimental tests; andoptimum die design parameters are found. forming process parameters including die opening angle,bearing length, clea...

However if current flows in the flux steering coils to produce a magnetic polarity, as shown in figure 2, the magnetic flux produced by the coils couples with the permanent magnet’s flux and the result is four units of force at one pole of the device (four units, not two, is due to the squared force law of the combined permanent magnet flux). Once the flux has switched and the actuation element...

We present a framework to design force fields that drive particles to follow a path under the physics-based animation system. In this framework, a user interactively specifies the desired path, represented by a Bezier curve using a GUI and the attraction force that drives a particle toward the target location. Then, the framework automatically defines the steering force to make a particle follo...

This paper presents analytical models to investigate the steering maneuvers of planetary exploration rovers on loose soil. The models are based on wheel-soil interaction mechanics, or terramechanics, with which the traction and disturbance forces of a wheel are evaluated for various slip conditions. These traction forces are decomposed into the longitudinal and lateral directions of the wheel. ...
