DYNAMIC MOTION ANALYSIS OF A WHEELCHAIR FOR PEOPLE WITH LOCOMOTOR DISABILITIES
The paper presents the kinematics and dynamics of a vehicle designed for the rehabilitation of people with locomotor disabilities. The transmission that ensures the movement of the vehicle is composed of two kinematic chains, one for traction and the other one that ensures the movement in curves and the orientation of the mechanical system. The two power trains are driven by two geared motors. The mechanical system is steered by two differential groups. The gear transmissions used are composed of worm gears, bevel gears and spur gears. A dynamic analysis of the drive kinematic chain is made in which the main component is a cylindrical gear. The system of equations defining the motion of the gear is solved by the modal superposition method.
