Study Power Management of Hybrid Electric Vehicle Using Battery Model Simulation
</title>
<link>http://pubs.sciepub.com/apa/1/1/1</link>
<description>
<![CDATA[This paper discusses the need for modeling and simulation of hybrid electric vehicle (HEV) Different modeling methods are presented with powertrain component and system modeling examples. The mattlab/simulink modelling and simulation of the hybrid electric vehicle (HEV) are represented in this paper. This simulation tool is meant as a help in the design and evaluation of the hybrid electric vehicle. Components in the driveline can be varied and the effect on the hybrid electric vehicle efficiency can be investigated. Both simulation tools are consist of a simulink vehicle model, where the driveline components are represented as interconnected blocks that are communicating physical signals between each other in the level of seconds. The demonstration shows different operating modes of the HEV over one complete cycle: accelerating, cruising, recharging the battery while accelerating and regenerative braking.]]>

Low Noise Intake System Development for Turbocharged I.C. Engines Using Compact High Frequency Side Branch Resonators
</title>
<link>http://pubs.sciepub.com/apa/1/1/2</link>
<description>
<![CDATA[Turbochargers have become common in passenger cars as well as commercial vehicles. They have an excellent mechanism to effectively increase fuel efficiency and engine power, but they unfortunately cause several noise problems. Its noise are mainly classified as structure-borne noises, generated from the vibration of rotating shaft modules (cartridges), and air-borne noises, from air flow inside turbochargers or their coupling ducts. In this study an attempt to reduce the pulsation noise generated from the compressor wheels, whose frequency is the same as the whine noise is presented. This attempt is based on using the compact high frequency side branch resonators to develop low intake noise system. The design of such system, which is mainly based on the developed 1D linear acoustic theory and theoretical investigations to use more than one resonator connected to the main duct in series and/or in parallel are introduced. An optimization strategy to choose the appropriate resonator axis offset is presented. In case of complex unsymmetrical geometry in real resonators, a 3 D finite element is used. The presented models are validated via comparison with the measured results at room temperatures. The validated models are used to improve the acoustic performance of the real resonators. Based on the developed models and the optimization results, the internal design of resonators improves its acoustic performance; the serial arrangements increase the damping at the same peak frequency while the parallel arrangements make it wider. The amount of extra damping added to the intake system depends on the resonators geometry and their axis offset which can be around 50 dB at the peaks, and 30 dB between peeks at normal operating engine conditions. Extra improvement to the intake system noise reduction can be achieved by redesigning and optimizing the entire system with used resonators under both space and shape constrains.]]>

Effect of Ambient Gradients on Sound Transmission in Narrow Permeable Rectangular Pipes with Application to Heat Exchangers
</title>
<link>http://pubs.sciepub.com/apa/1/1/3</link>
<description>
<![CDATA[The effect of ambient gradients on sound propagation in air filled narrow tube was investigated. The narrow tubes were taken to be nominally straight with very small pores in the walls. The solution includes the effect of a static pressure, temperature and density gradients in the presence of mean flow, which is assumed to have a uniform velocity profile. A dispersion equation is derived by assuming the spatial variations of the ambient variables can be lumped by using their average values. The complex wave number, density, speed of sound and the characteristic impedance of such media were evaluated. An application to fulfil narrow tubes with rectangular cross section and permeable walls such as; heat exchangers is developed and presented. An accurate acoustic model based on two-port matrix to calculate the transmission losses in the heat exchanger (HE) taking the ambient gradients effects into account are developed and used to study and improve the acoustic performance of HE. The developed model is validated with the measured results using normal incident and diffuse field at room temperature and a good agreement is achieved. Based on the results presented in this paper, the acoustic performance of the existing heat exchanger is bad especially at low frequencies, the operating conditions have some positive effects on its performance and its acoustic performance can be improved through channel wall impedance. Extra improvements are still needed to use it as a passive noise control element to damp the fan noise.]]>

Fuzzy Self Tuning of PID Controller for Active Suspension System
</title>
<link>http://pubs.sciepub.com/apa/1/1/4</link>
<description>
<![CDATA[Suspension system plays an imperative role in retaining the continuous road wheel contact for better road holding. In this paper, fuzzy self-tuning of PID controller is designed to control of active suspension system for quarter car model. A fuzzy self-tuning is used to develop the optimal control gain for PID controller (proportional, integral, and derivative gains) to minimize suspension working space of the sprung mass and its change rate to achieve the best comfort of the driver. The results of active suspension system with fuzzy self-tuning PID controller are presented graphically and comparisons with the PID and passive system. It is found that, the effectiveness of using fuzzy self-tuning appears in the ability to tune the gain parameters of PID controller]]>
