Abstract:
Passengers who travel in rickshaws in Bangladesh often face serious issues due to the
uncomfortable sitting arrangements which can cause pain, health hazards from prolonged
vibration exposure. Due to these vibration on the human body, several health issues can occur
such as muscle strain and sprains, back and spinal issues, joint pain, whiplash effect, fatigue
and internal injuries, etc. The goal of this research was to fabricate a portable seat that will
work as an energy-absorbing component and reduce vibration resulting from the jerking effects
of the road, reducing the adverse acceleration of the body of the passenger. Previous studies
have mostly focused on seats in trains and buses, ignoring the seats of rickshaws. To address
this issue, a portable seat has been fabricated that can be easily integrated with the current
rickshaw system. Two distinct combinations of various impact-absorbing materials have been
used here in this research, and the performance of the portable seat were evaluated using
experiments. Through the experiments, it was evident that the portable seat reduced the
acceleration of the passenger body resulting from the jerking effects of the road by absorbing
the direct impact of the jerking effect, especially the acceleration of the lower back of the
passenger. The results of the experimental tests which were conducted with both of the
combinations of the energy-absorbing materials, were compared in which, one of the
combinations exhibited better reduction of the vibration. It can be concluded that this initiative
is very important for promoting safer and more comfortable ways of transportation, which will
enhance everyday experiences and the general quality of traveling for rickshaw riders.
