چکیده
A hydraulic engine mount (HEM) is an advanced tuned mass damper (TMD) system used to isolate the noise and vibration from chassis. This paper aims design a semiactive HEM based on TMD model, which only tunes damping without affecting other lumped parameters of system. Firstly, dynamic equations modeled as are derived linear parameter model (LPM). Each analyzed identify relevant that affect damping. Secondly, newly designed proposed utilizes helical moving plate simultaneously control both inertia track area length, resulting in precise tuning. To illustrate performance HEM, calculations presented various for its tunable range stiffness spectrum. Additionally, demonstrate isolation, this determines optimal length minimize transmissibility. Thirdly, reveal superiority over MR fluid mount, example where medium place conventional while keeping all constant. Specifically, novel employs spiral-driven by fluid-based controlled additional magnetic intensity controller. The nonlinear LPM verified comparing spectrum with experimental results published literature. Then, established, calculated compared HEM. indicate have similar ranges control, but does not require expensive MR/ER or continuous external energy input regulate stiffness. Moreover, when using inexpensive low-viscosity fluid, can provide wider control.

متن کاملA Rheological Model for Magneto-rheological Fluids
Magneto-rheological fluids (MRF) are suspensions of particles which can be magnetized. MRF exhibit fast, strong and reversible changes in their rheological properties when a magnetic field is applied. A commercially available damping system that takes full advantage of the controllable technology of MRF and delivers valveless damping control appeared on passenger vehicles in 2003. Further comme...
