Brake squeal is a manifestation of friction-induced self-excited instability in disc brake systems. This study investigated non-smooth bifurcations and chaotic dynamics in disc brake systems and elucidated a chaotic control system. Decreasing squeal noise which is dependent on chaos, increases passengers comfort; consequently, suppressing chaos is crucial. First, synchronization was used to estimate the largest Lyapunov exponent to identify periodic and chaotic motions. Next, complex nonlinear behaviors were thoroughly observed for a range of parameter values in the bifurcation diagram. Rich dynamics of the disc brake system were studied using a bifurcation diagram, phase portraits, a Poincare map, frequency spectra, and Lyapunov exponents. Finally, the proposed technique was applied to a chaotic disc brake system through the addition of an external input that is a dither signal. Simulation results demonstrated the feasibility of the proposed approach.

The main objective of this study is to investigate ways to reduce the aerodynamic drag coefficient and to increase the stability of full-size road vehicles using three dimensional Computational Fluid Dynamics (CFD) simulations. The baseline model of the vehicle used in the simulation is the Land Rover Discovery. There are many modern aerodynamic add-on devices which are investigated in this research. All of these devices are used individually or in combination. These add-on devices should not affect the vehicle capacity and comfort. In this study three velocities of the air is used: 28 m/s (100.8 km/hr), 34 m/s (122.4 km/hr) and 40 m/s (144 km/hr). The calculated drag coefficient for the baseline model of Land Rover Discovery agrees very well with the experimental data. It is clear that the use of a ventilation duct has a significant effect in reducing the aerodynamic drag coefficient.

Fuel efficiency in hybrid electric vehicles requires a fine balance between combustion engine usage and battery energy, using a carefully designed control algorithm. Owing to the transient nature of HEV dynamics, driving conditions prediction, have unavoidably become a vital part of HEV energy management. The use of vehicle onboard telematics for driving conditions prediction have been widely researched and documented in literature, with most of these studies identifying high equipment cost and lack of route information (for routes unfamiliar to the GPS) as factors currently impeding the commercialization of predictive HEV control using telematics. In view of this challenge, this study inspires a look-ahead HEV energy management approach, which uses time series predictors (neural networks or Markov chains), to forecast future battery state of charge, for a given horizon, along the optimal front (optimal battery state of charge trajectory). The primary contribution of this paper is a detailed theoretical appraisal and comparison of the neural network and Markov chain time series predictors over different driving scenarios (FTP72, SC03, ARTEMIS U130 and WLTC 3 driving cycles). Based on the analysis performed in this study, the following useful inferences are drawn: 1. Prediction accuracy decreases massively and disproportionately on average with increased prediction horizon for multi-input neural networks, 2. In a single-input/single-horizon prediction network, the performance of both the neural network and Markov chain predictors are similar and near optimal, with a mean absolute percentage error of less than 0.7% and a root mean square error of less than 0.6 for all driving cycles analysed, 3. Markov chains appeal as a promising time series predictor for online vehicular applications, as it impacts the relative advantage of high precision and moderate computation time.

In this work the tribofilm development mechanisms in three severity levels on the field application were correlated with those simulated in a pin-on-disc tribometer. It was found that the tribofilm characteristics depend on the severity of application. In addition, the pin-on-disc tribometer can reproduce the same mechanisms that were identified on the field, due to the parity between the tribosystem characteristics of test model and field condition.

The aim of this study is to provide experimental results for assessing diesel-biodiesel-ethanol (DBE) blended fuels as future technology for efficiently using these three fuels and for reducing engine emissions. The results included engine performance, brake specific emissions and soot properties for diesel-biodiesel blended with 0%, 5%, 10% and 20% ethanol tested at steady speed of 1800 rev/min under different engine loads. It was found that DBE blends can reduce NOx, CO2, volatile organic fractions and particulate mass-number concentration with improved thermal and combustion efficiency while slightly decreased the particle size.

ZrB2-SiC ultra-high temperature ceramic composites have been considered to be the optimal candidate for using in extreme environments. The present communication for the first time applied aqueous electrophoretic deposition for successfully preparing ZrB2-SiC nano-composites in pulsed DC electric fields. The deposition behavior was investigated based on the influences of applied voltage, duty cycle and frequency. A smooth, uniform and pore-free ZrB2-SiC nano-composite was successfully synthesized. The highest green density of 67.1% was achieved for the nano-composite with the SiC content of 26.7 wt.%. We believe that the present research will open up a new horizon in preparing bulk ceramic composites or composite working parts in industries.
