The main role of the suspension system is to achieve ride comfort by reducing vibrations generated by the road
roughness. The active damper is getting much attention due to its reduced cost and ability to enhance ride comfort especially
when the road ahead is measurable by an ...
We assessed the effect of wearing a junior-high-school helmet when the frontal or lateral part of a helmet
impacted the upper part and lower part of the A-pillar of a vehicle at 35 km/h (212 J). The head injury criterions (HICs) of
the headform impactor without a helmet were r...
Timoshenko beam element of variable cross-section rectangular tube is developed and applied in the
lightweight design of bus frame in this paper. Firstly, the finite element formulations of variable cross-section beam (VCB) are
derived under the loadsteps of axial deformation,...
Whiplash injuries are one of the most common injuries reported in automotive rear end collisions. Automobile
seat back and head restraints play a role in reducing neck injuries during low speed rear end collisions. Currently, many studies
are being conducted on ways to reduce ...
The purpose of this paper is to verify if it is possible to recover the energy from automobile suspensions, using
a system who replace the shock absorber. The system consists of an electric generator, a mechanical system for transforming
the translation of body car in rotation...
This study was carried out to investigate the creep life at the high temperature of the Alloy 718 for automotive
engine components using the initial strain parameter method (ISPM). Creep tests have performed at elevated temperatures in
the range of 550 oC to 700 oC in this wor...
Recently Plug-in hybrid electric vehicles (PHEVs) have gained increasing attention due to their ability to
reduce the fuel consumption and emissions. In this paper a new efficient power management strategy is proposed for a series
PHEV. According to the battery state of charge...
In this paper, a robust sideslip angle controller based on the direct yaw moment control (DYC) is proposed for
in-wheel motor electric vehicles. Many studies have demonstrated that the DYC is one of the effective methods to improve
vehicle maneuverability and stability. Previo...
A reduction gear of an in-wheel motor vehicle is mounted between a traction motor and wheel, to increase the
wheel torque and decrease the rotational speed. To improve the energy efficiency of a vehicle, the determination of the optimal
gear ratio is an important factor in the...
An electrically assisted internal combustion engine is obtained by combining a conventional engine and one or
more electrical motors of considerably smaller size. A key feature of such an innovative vehicle hybridization approach is that
the torque generated by electric machin...
In this study, in order to examine the cooling efficiency of a carbon-ceramic brake disk, the temperature
distribution of the disk, depending on the AMS (Auto-Motor-Sport) Fade mode, was analyzed using a numerical method. Two
brake disks with different straight ventilation hol...
In this study, the effect of hydrothermal aging over a commercial diesel oxidation catalyst (DOC) on
deterioration in nitrogen dioxide (NO2) production activity has been experimentally investigated based on a micro-reactor
DOC experiment. Through this experimental result, the ...
Solar road vehicles have very specific design requirements. This makes their aerodynamic characteristics quite
different from classic sedan vehicles. In the present study, the computational model of a typical solar road vehicle was
developed to investigate its aerodynamic forc...
This paper proposes a DC motor current control algorithm using a proportional-integral linear quadratic
tracking (LQT) controller with a disturbance observer for the electronic stability control (ESC) brake system. Previously
researched algorithms related to current control us...
Function integration is the way used commonly to achieve the lightweight design system. To realize the design
successfully by combing two systems multifaceted issues in need to be considered. The potential functional conflicts between
the existing systems are the major unfavor...
Linear acoustic theory is used for estimating the acoustical performance of the air cleaner box composed of the
porous filter and encasing box in the engine intake system. The pleated filter structure is modeled as coupled multiple ducts
having permeable micro-perforated walls...
A lateral acceleration is considered to be a significant sensor signal for an estimation of a side slip angle. Due
to the fact that a characteristic of a lateral G sensor, the sensor has a technical issue when a road bank angle has presented.
In order to resolve the issue, thi...
