Abstract
Adapting a car for a disable person involves adding additional equipment to compensate for the driver’s disability. During this process, the change in the driver’s position and kinematics and their impact on safety levels during crash is not considered. There is also a lack of studies in the literature on this problem. This paper describes a methodology for conducting a study of the behavior of a disabled driver during a crash using the finite element method, based on an explicit time integration method. A validated car model and a commercial dummy model were used. The results show that the use of a handle on the steering wheel and a hand control unit causes dangerous lateral displacements relative to the seat. Amputation of the left leg or right arm causes significant shoulder rotations, amputation of the left leg causes increased thoracic loads. Amputation or additional equipment have no significant impact on head injuries.
Highlights
Over a billion people live with some form of disability, which represents 15% of the world’s population [1]
The authors of [2] point out that the acquisition of a disability is associated with a reduced ability to work, greater functional dependence, greater need for assistance, and the need for family support
The main objective of this article is to examine the impact of the change in the position of the driver’s mass, caused by various types of disabilities or the use of specialist equipment, on the driver’s biomechanical parameters
Summary
Over a billion people live with some form of disability, which represents 15% of the world’s population [1]. Researchers from all over the world carry out research related to different aspects of DPs’ lives, looking, for example, at how they spend their leisure time [3], how well the infrastructure fits their needs [4,5,6], or their preferences when making choices [7] These people in many cases possess valuable skills. Understanding the specific requirements of this social group allows the development of technical solutions that remove barriers that prevent them from active functioning, socially and professionally. This will enable the public to benefit from these skills
