Study on Vertical Vibration System of Person-Seat-Suspension of Electric Wheelchair

In order to reduce secondary injuries due to the Electric wheelchair vibration, the author established the mathematical model of the vertical vibration of the electric wheelchair person-seat-suspension coupling system. The vibration equation of the wheelchair-road coupling system is theoretically studied to study the interaction and coupling between the wheelchair and the road. This research result can be used to optimize the performance of the wheelchair suspension system, improve the comfort of the rider and avoid the secondary injury of the body.
