510 Modeling to impact effect for handicapped people on the wheelchair during vehicle driving
Details
A lot of handicapped people feel endangered when they travel in the vehicle with them sitting on the wheelchair. But no safety standard is applied to the handicapped people sitting on the in-vehicle wheelchair during driving. The object in this study is to make models to simulate the behavior of handicapped people on the wheelchair. Human body sitting on the wheelchair is expressed by a link segment model of two degrees of the freedom with muscle reflection in which Hills' muscle models are applied and muscle activity is modeled. The carriage on which the wheelchair is fixed and handicapped people sat on the wheelchair was run into the fixed rigid wall through shock absorber. The cervical angle and muscle activity were measured and they are compared with the simulation result.
