Abstract: A two-dimensional model for a trochoidal-type machine without apex seals using finite element method has been developed with the help of Cosmos/M V1.65, and is evaluated by using a classical ...

Abstract: In a trochoidal-type machine, the friction and wear due to the apex seal is a major problem. In order to increase the efficiency and reliability of this type of machine, we propose to replace ...

Abstract: This paper presents a wheelchair velocity feedback controller intended to reduce the control demands on a wheelchair driver in outdoor driving and in low speed maneuvering. A dynamic model of ...

Abstract: This paper describes a computer model of a wheelchair and its motor control circuitry. The model simulates the wheelchair’s motion in driving on a sloping surface, and is intended to facilitate ...
