Paper Abstract
A solid mechanical spring generally exhibits uniform stiffness. This paper studies a mechanical spring filled with
magnetorheological (MR) fluid to achieve controllable stiffness. The hollow spring filled with MR fluid is subjected to a
controlled magnetic field in order to change the viscosity of the MR fluid and thereby to change the overall stiffness of the
spring. MR fluid is considered as a Bingham viscoplastic linear material in the mathematical model. The goal of this
research is to study the feasibility of such spring system by analytically computing the effects of MR fluid on overall
spring stiffness. For this purpose, spring mechanics and MR fluid behavior are studied to increase the accuracy of the
analysis. Numerical simulations are also performed to generate some assumptions, which simplify calculations in the
analytical part. The accuracy of the present approach is validated by comparing the analytical results to previously known
experimental results. Overall stiffness variations of the spring are also discussed for different spring designs.
