“…The dynamic model of the brake mechanism can include the brake rotor, piston and other elements. 19,20 The model refinement depends on the requirements of the research tasks. In this article, the first objective is the representation of the hysteresis characteristic for the task of vehicle braking dynamics.…”

Shyrokau, Barys; Wang, Danwei; Augsburg, Klaus; Ivanov, Valentin: Vehicle dynamics with brake hysteresis URN:urn:nbn:de:gbv:ilm1-2014210177 AbstractThis paper studies hysteresis of vehicle brakes and its influence on the vehicle dynamics. The experimental investigation clearly shows the non-linear and asymmetric characteristics of hysteresis of the disk brakes in passenger cars. A computational model of the brake mechanism with hysteretic elements, based on the Bouc-Wen method, is developed and verified with experimental data. Using the developed model, the influence of hysteresis on the vehicle dynamics during straight-line braking with an anti-lock braking system is analysed. It is also observed that the variations in the hysteresis parameters have important influences on the main vehicle brake characteristics such as the stopping (brake) distance, the time of braking and the average deceleration. A comparative analysis of the simulation results is also given for braking with zero hysteresis or with hysteresis represented as a signal delay and linear function.

Investigation of Traffic‐induced Vibration in Vilnius Arch‐cathedral Belfry

2008

View full text Add to dashboard Cite

The influence of city traffic-induced vibration on Vilnius Arch-Cathedral Belfry is investigated. Two sources of dynamic excitation are studied. Conventional city traffic is considered to be a natural source of excitation while excitation imposed artificially by moving a heavily loaded truck is considered to be the source of increased risk excitation. The influence of induced vibrations is recorded by accelerometers located in various positions of the Belfry's structures and shown by accelerograms. Dynamic effects are evaluated by considering acceleration magnitudes and response spectra. A comparative analysis of both effects is presented and conclusions and recommendations are provided.

“…They found that longer stopping sight distances are required under curves driving conditions using the revised stopping sight distance formula [17]. Moreover, while many researchers have questioned the validity of the basic model [18–20], many researchers investigated the effect on the braking performance of different road, weather, driving conditions and driver behaviours [21–30]. Determining the safe stopping distance based on the driver, environment (weather and highways conditions) and vehicle conditions is not only for drivers but also important for safety management and other road users.…”
