Multi-Physics Analysis of a Magnetorheological Valve Train with Experimental Validation

Magnetorheological (MR) fluid devices are widely used in active automotive control applications. However, MR fluid-based valve actuators not the limelight. This paper proposes a new flexible train with an system; can enhance performance of internal combustion engines. A major component this is magnetic plate block filled and surrounded by coil. controls field eventually facilitates lifts opening timings. study overviewed conceptual design, two-way coupled multi-physics numerical simulations, manufactured prototype, conducted experimental tests on test bench to understand real-time train. First, computer simulations were performed using thermal multiphysics model consider Joule-heating effect coil block. The simulation results indicated that although temperature increased noticeably, it did exceed prescribed operating limits. dimensions optimized. After optimization, prototype proposed was fabricated tested its real time. reliability practical scenarios.
