Magnetic Suspension System

This paper presents a research work on magnetic suspension system of two wheelers Automobiles, which are usually depending on spring type, Hydraulic and Pneumatic suspension systems. In this proposed magnetic suspension system, two permanent magnets made of Neodymium material are placed inside the shock absorber cylinder such that both facing same pole. So they produce a repulsive magnetic flux force, when they come closer due to shocking load. This repulsive magnetic flux force is used as shock absorbing media and provides damping force. Proposed suspension system proves to be more efficient over other type of suspension systems, absorb more number of shocks with high accuracy, has no leakage problem unlike in Hydraulic and Pneumatic system. So all these beneficial qualities make the magnetic suspension system to work efficiently with less maintenance cost and hence the Automobile.

Magnetic Suspension System

This paper proposes a new type of noncontact magnetic suspension system using two permanent magnets driven by rotary actuators. The paper aims to explain the proposed concept, configuration of the suspension system, and basic analyses for feasibility by FEM analyses. Two bar-shaped permanent magnets are installed as they are driven by rotary actuators independently. Attractive forces of two magnets act on the iron ball which is located under the magnets. Control of the angles of two magnets can suspend the iron ball stably without mechanical contact and changes the position of the ball. FEM analyses have been carried out for the arrangement of two permanent magnets and forces are simulated for noncontact suspension. Hence, successfully the required enough force against the gravity of the iron ball can be generated and controlled. Control of the horizontal force is also confirmed by the rotation of the permanent magnets.

And Performance

This paper proposes a noncontact operation robotic hand using magnetic suspension system. This robotic hand will consist of a noncontact catching part and four movable fingers. The noncontact catching part will be realized by a permanent magnetic suspension system, and will be used to pick up and catch the metal body. There is a permanent magnet on the top of each moveable finger, which operates the suspended metal body without contact. This paper focuses on the feasibility and performance of the noncontact operation using the movable fingers with permanent magnets.

The One

The vehicle is one of basic needs for supporting mobility of people. Comfort and safety are demanded in every vehicle, especially in its suspension system. The existing suspension systems can’t maximize comfort and safety because it is still hydraulic and pneumatic based, without magnetic system. The purposes of the analysis is building magnetic suspension system with variations at the amount of coil and analyzing absorbing time. The methods of the analysis are determining concept, making the designs, determining components specification, making device block diagram, making wiring diagrams, making the device, taking the absorbing time datas, and the analyzing the data. The results of the analysis are the amount of coil is straight compared to the magnetic force and absorbing time. The most significant solenoid is the one which has 900 coils and has absorbing time at 9.6 seconds.

Fuzzy Sliding Mode

This paper presents the two-dimensional fuzzy sliding mode control of a field-sensed magnetic suspension system. The fuzzy rules include both the sliding manifold and its derivative. The fuzzy sliding mode control has advantages of the sliding mode control and the fuzzy control rules are minimized. Magnetic suspension systems are nonlinear and inherently unstable systems. The two-dimensional fuzzy sliding mode control can stabilize the nonlinear systems globally and attenuate chatter effectively. It is adequate to be applied to magnetic suspension systems. New design circuits of magnetic suspension systems are proposed in this paper. ARM Cortex-M3 microcontroller is utilized as a digital controller. The implemented driver, sensor, and control circuits are simpler, more inexpensive, and effective. This apparatus is satisfactory for engineering education. In the hands-on experiments, the proposed control scheme markedly improves performances of the field-sensed magnetic suspension system.
