A physical model of a vehicle engine mount incorporating a magnetorheological (MR) damper in squeeze mode is investigated and the structural design and operating characteristics of the MR damper are provided. The mathematical model of an engine mount is formulated. Kinematic excitations are assumed to be those emulating road profile-chassis (car body) interactions. Simulations of engine vibration are performed to determine the efficiency of the proposed engine mount. Conclusions are drawn concerning the potential applications of the MR damper in vehicle engine mounts.

W pracy opisano budowę modelu fizycznego zawieszenia silnika samochodowego, w którym zastosowano tłumik z cieczą magnetoreologiczną (MR) działającą w trybie ściskania. Sformułowano model matematyczny zawieszenia. Zakładając wymuszenie kinematyczne modelujące oddziaływanie nierówności drogi na karoserią, przeprowadzono symulacje komputerowe drgań silnika. Oceniono efektywność działania zawieszenia oraz sformułowano wnioski dotyczące możliwości zastosowania tłumika MR w zawieszeniu silnika samochodowego.
