Abstract: The present paper deals with design, modelling
and characteristics of a biomedical system. The involved biomedical system
is a syringe pump generally used for continuous drug infusion. The syringe
pump consists of a linear switched reluctance motor (LSRM) coupled to a
syringe plunger. In order to determine the axial force to control the
syringe plunger, it was necessary to begin by evaluating the thrust force.
For that purpose, an analytical approach is developed to evaluate the
different forces and pressures involved. In addition, an experimental bench
was conceived to determine the thrust force and validate the analytical
model of the syringe. Consequent results constituted the key element for
designing and modelling the LSRM with the help of finite element methods
(FEM). The final step is reserved to predict the dynamic performances of all
the biomedical system with and without saturation.
Keywords: Linear switched reluctance motor, syringe pump, modeling, finite-element methods and dynamic performances
