| Summary: | MR fluid is a smart liquid where its properties can be controlled by the presence of
magnetic field. Studies for MR fluid device has also been researched such as MR
dampers, MR valves, MR brakes, MR mounts, and so on. In this thesis, the
comparison for original damper and MR fluid damper is one of the main focus. The
carrier fluid has been benchmarked in order to decide which is the best carrier fluid to
be carried on in this experiment. There are two (2) types of experiment conducted for
this project which are, sedimentation test and static test. The purpose of sedimentation
test is to study the different composition of MR fluid and decide which is the best MR
fluid mixture. For this experiment, several specimens have been prepared by varying
the composition of carrier oil and Carbonyl Iron Particle while the additive
composition is fixed. Static test is conducted in order to study the performance of
original damper and MR damper. Permanent magnet is utilized in order to generate a
magnetic field as opposed to an electromagnet due to safety precaution. With the
presence of magnetic field, the MR damper when in active and passive state are
investigated. |
