Flywheel systems based on fibre composites can have power densities which are significantly better than for electrochemical batteries. Hence, they have considerable potential for use as peak power buffers in drive-trains for electric and hybrid vehicles. As the rotational speed is increased, however, bearing friction power loss and iron losses in the motor/generator become more significant. Thu...

C This paper provides a design outline and implementation procedure for a Secondary Energy Storage Unit (SESU) that can be used to meet the peak energy requirements of an electric vehicle during both acceleration and regenerative braking. The life cycle of the electric vehicle’s batteries can be extended considerably by supplying peak energy requirements from a secondary source. A simulation st...

A novel application, employing the strategy of Active Disturbance Rejection Control and an Extended State Observer, is proposed to control the rotor shaft position of NASA’s High Speed Shaft (HSS) Flywheel using active magnetic bearings. The robustness of the control is demonstrated in a frequency domain analysis and in simulations to be a major improvement of controls recently studied at NASA.

A damping strategy using a friction ring damper for an industrial flywheel was numerically and experimentally investigated. The damper, located on the arms of flywheel, found to effectively reduce vibration amplitude flywheel. energy dissipated when relative motions occur at contact interfaces. Nonlinear dynamic analysis based lumped-parameter model equipped with conducted. normal load, N, used...

This paper presents the integration of a novel mechanical torsion spring regulator into pendulum energy harvester system. was designed to provide same voltage-smoothing benefits flywheel without start-up issues caused by increasing system inertia. In addition, introduction between input and output stages device acts as buffer for any sudden impacts, which not only allows from such events be ful...

The robot is being used in many applications for a different domain. delivery was developed, and the battery placed power source. Considering abnormal condition/situation during disaster period, energy critical issue robot. To overcome this condition, three kinds of sources were identified such as (i) direct energy, (ii) solar (iii) flywheel storage energy. All systems designed found that can b...

The planetary flywheel can significantly reduce the weight of flywheel, allowing inerter to be lightweight. When a ball screw inerter-based active actuator is used in vehicle suspension system, nonlinear features affect performance. actuator’s dynamic model constructed this study based on and electromagnetic torque generating mechanism permanent magnet synchronous motor. impact screw–nut fricti...
