| Summary: | Magnetorheological Fluid is a smart fluid that its properties can change depending on the environment that influence it. Changes phase indicates the viscosity changes affected the magnetic field. Bonds between the particles are formed in the direction of the magnetic field that can be created with elektromagnetnya anticipate. The advantages of MR Fluid is the dynamic yield strength can be changed when there is the influence of the magnetic field so many applications such as shock absorbers, dampers, etc.. In the present study will be discussed further on the direction of the magnetic field effect on the characteristics of the MR fluid Fluid when it was given with some variations impact loads and loads magnetic field. In addition, this study will concentrate on experiments with low-intensity magnetic field. Characteristics of MR Fluid will be scrutinized by showing changes in the distance the piston, piston speed, and pressure that occurs in the presence of a research tool when the impact force applied to the system. The study was conducted with the MRF-122EG fluid is put into the shock absorber that given the impact load through the piston stroke length of 80 mm. A shock absorber piston orifice installed in it and an electromagnet with the affected area magnetic field just outside the orifice. Impact load of 3.4 kg, 5 kg, 6.6 kg, 8.2 kg is dropped from a height of 500 mm with a loader from the highest point of the piston. The magnetic field used in the study is the magnetic field perpendicular to the direction of the pipe is made by putting together two flanking shock absorber solenoid core. The magnetic field used in this study has intensity 0 mT - 100 mT. Exposure phenomenon and analysis of MR Fluid characteristics that occur using data from SRF04 distance sensor and a pressure sensor MPX 5100 DP is directly connected to the PC. The result is the shock absorber damping increases as the magnitude of the applied current. It can be read from the velocity after impact is lower and the time needed to reach the farthest point of the longer. Comparison between the shock absorber damping fluid before the turn of the shock absorber with the MRF- 122EG fluid looks much different in terms of speed and time.
