Abstract
Powered Two Wheelers (PTW) are very sensitive to environmental conditions and advancement in two-wheeler safety has not kept pace with the advancement in two-wheelers. The objective of our research is to bring about an improved design for powered two wheelers, analyzing the changes through simulation and thereby improving the safety considerations. According to the databases referred regarding accidents in depth study, it is observed that two-wheelers top the chart in number of accidents by a big margin and these accidents causes more fatal injuries. To save the rider, this paper proposes to constraint the rider along with pillion to the vehicle using “Leg holding device“ and seat belt. Side airbags are employed to absorb the impact of accident. The present safety system saves the rider in frontal collisions, while this research also focuses on side collisions. ISO 13232 standard accident scenarios were followed. For simulation of scenarios multi body dynamics software called RecurDyn is used. The improvement in employing safety measures is compared with its absence and results are plotted.
How Multibody Dynamics Simulation Technology is Used
RecurDyn was used to simulate the crash of a powered two-wheel vehicle with and without additional safety constraints. The forces on the different joints on the body could be tracked over the course of the crash. The result was that a design was reached that could improve the overall safety of a two wheeled vehicle during a crash.
