| Summary: | With the rise in popularity of Personal Mobility Devices (PMD) worldwide, it encourages an
alternate form of transportation for short trips around the neighbourhood in world that is
slowly pushing for more Electric Vehicles to be on the road and phasing out of convention
vehicles that is fuelled by the internal combustion engine. In fact PMDs are actually out
worldwide and used by many years ago from hoverboard to motorised wheelchair. One of
the PMDs this report will be focusing on is the Power Assisted Bicycle (PAB). The more
notable differences between PMDs and PAB will be the ability to operate when the vehicles
are out of battery. After the PAB run out of battery , the user are still able operate the
vehicle by just pedalling like a conventional bicycle. At the same time, power translating
from pedalling and the battery allows the PAB to go onto a higher speed. While the PMDs
will stop and unable to move went it runs out of battery.
Increase in commuting using of PABs on the road, naturally the accident rates will slowly
creep up and then caught the attention of the local authorities. Since the PABs are new to
the community, limited researches are performed to conclude a precise injury log that can
potentially cause by accidents where PAB is involved. One approach to tackle these issue is
to use an accident reconstruction software called Virtual CRASH also known as vCRASH.
vCRASH is an accident reconstruction software that is able to mimic accidents as closely as
possible. Data generated from vCRASH can be used to analyse and interpret the damaged
that can be inflicted to the rider taking account to the throw distance from the point of
collision and head velocity when it touches the ground as the head is always on of the most
vulnerable body part of a human.
Overall, employing the usage of vCRASH to reconstruct accidents between PAB and a
vehicle(car) at the point of collision has facilitated in attainment the FYP’s goal. One
important relation can be deduce from the simulations is the Vehicle’s speed(car) at the
point of collision has proven to be the important factor affecting the final results with the
cargo weight close to negligible in accounting for the Multibody’s Average Head Velocity,
Multibody’s Average Head Throw and Multibody’s Average Top Velocity.
