In this paper an optimal controller is proposed for a self-balancing electrical vehicle called Segway PT. This vehicle has one platform and two wheels on the sides and the rider stands on the platform. A handlebar, as a navigator, is attached to the body of Segway, with which the rider controls the vehicle. Since Segway uses electrical energy produced by batteries, resource consumption manageme...

In distribution networks, failure to smooth the load curve leads to voltage drop and power quality loss. In this regard, electric vehicle batteries can be used to smooth the load curve. However, to persuade vehicle owners to share their vehicle batteries, we must also consider the owners' profits. A challenging problem is that existing methods do not take into account the vehicle owner demands ...

In a rail vehicle, fatigue fracture causes significant number of failures in the coil spring suspension system. this work, origin these is examined by studying wheel–track interaction, modal analysis springs and stresses induced during operation. The tested experimentally, mathematical model developed to show its force vs. displacement characteristics. A vertical 10-degree-of-freedom (DOF) full...

In this paper, the vehicle faults are estimated and diagnosed by introducing wavelet transform, based on the state-space method. It monitors the state of railway vehicle suspension system, establishes a vertical dynamic state-space model of railway-vehicle system to identify the parameters of vehicle suspension system. The simulation results show that, in the circumstances of the change of the ...

On account of the influence discontinuity CRTS II ballastless track slabs and discrete support pads on high-speed rail vehicle-ballastless system, a vibration analysis calculation model track-vehicle coupling system was established basis moving unit method. The dynamic response at different travel speeds with without consideration plate discontinuities investigated. effect random process steel ...

The requirements for track loading limits are one of the main barriers to simple crossacceptance of vehicles where rolling stock that is already operating successfully in one (or more) networks has to be re-tested before it can be approved for operation on another network. DynoTRAIN WP 4 studied this area in order to determine whether the additional requirements were justified, or if the proces...

Lightweight is an important measure to the fuel efficiency and the cost reduction in development of contemporary vehicles. However, how the lightweight structure could affect the NVH performance or ride comfort of a vehicle needs to be carefully investigated. In this paper, the effect of a lightweight rear differential unit of a sport utility vehicle on ride comfort was studied. A multi-body dy...
