| Summary: | An advanced suspension system recommends more handling, safety, comfortable ride and fast reaction.
Such a system is capable to scan changing of road profile and its conditions and also monitor
factors such as car speed and steering wheel angle. Application of different sensors
such as laser sensor or stereo camera for scanning road profile and different types of
mechanical mechanism such as hydro pneumatic or hydraulic system for readjusting axles are
challenges between car manufacturers. In this research, a new method is proposed for improving
the vertical movement mechanism in suspension system of vehicles. The proposed method is
based on vertical movement mechanism which is equipped with a monitoring system to scan the
road profile for stabilizing car chassis. This system will analyze steering wheel angle, weather
conditions, the distance between cars during accident and car speed in order to adjust the height
of the car’s axles accordingly. Such mechanism can increase comfortability, car handling stability
and safety by reducing the vertical movements. Besides that, the proposed system will increase the
safety of the passengers by reducing vertical movements that may cause car’s imbalance or
rollover during driving. A prototype of a vertical movement model was developed to simulate its
function during different driving profiles and conditions. The purpose of the simulation based on
the half-car model is to utilize the function performance of the device in a
laboratory scale. It is worth to note that the proposed method successfully reduces the
vertical movement up to 33% compared to normal suspension system. While the model reduces the
impact during an accident of 44% for contact between car bumpers. In summary the
system successfully adjusts the height of axles according to car speed, weather condition
and steering wheel angle to prevent of rollover of the car. This system can be used in the
automotive industry for passenger cars and light trucks. Furthermore, with some modifications, this
system can be applied in mass transit, aerospace industry and
marine transportation. |
