“…9gives the relationship for the maximal forward speed determination valid for a four-wheeled vehicle. From the derived equations (8) and (9) we can identify that l F is always less than L, the speed at which rollover for the classic tricycle will always be lower than for the corresponding new designed tricycle.…”

The article deals with the design of a modified system for changing of the driving direction of a threewheel vehicle with electric drive. The classic solution of three-wheeled vehicles is unstable at a certain speed, which leads to dangerous tilting. The new designed steering system of such a vehicle should contribute to increasing its safety and to widening the scope for its use. The vehicle is currently designed for one person, but it is expected to increase its capacity to two persons and their luggage. It brings changes in a construction of the vehicle and results in a change in the centre of gravity. The modified solution of the vehicle steering system increases its maximum speed. The vehicle construction consists of an electric drive located above the rear axle with torque transmission to the rear wheels. The front wheel is steered. The classic steering solution is replaced by a steering wheel that facilitates steering. The article compares the stability of a vehicle with a modified steering system to the conventional solution during driving in a curve. The calculations were performed for various speeds using the multibody simulation on the virtual model in Simpack software. The solution is a part of the project supported by the Volkswagen Slovakia Foundation oriented on the support of electromobility, students and young scientists.

Abstract:The ride comfort for passenger represents an important aspect of a rail vehicle dynamic analysing. The computational software utilisation helps to determine forces and accelerations in various positions through the body of a rail vehicle in order to predict ride properties or evaluate ideas for ride comfort in advance. This article is focused on the dynamic simulation of a rail vehicle running on a real track section. The rail vehicle model creation, computations performance and determination of accelerations badly needed for the ride comfort evaluation is performed in commercial software package.

“…Moreover, the measured signal can be processed by means of bandpass filters, spectral analysis and wavelet method. 2,7,8 For example, filters are useful to extract fault-relevant information from vibrational measurements. Phase differences between rotational and translational motions are employed in Kojima and Sugahara 9 in order to detect faults of suspension elements.…”
