Control of Engine Roll and Bounce Vibrations Using Hydraulic Mounts

Vibration control of an automotive engine using active mounts

In this research, vibration control of national engine (EF7) using active mounts is studied for two different mounting layouts. The first layout is based on the current engine mounting of national engine (system of three passive mounts), but the hydraulic mount is substituted by an active mount. The other mounting layout contains 4 mounts, 2 of which are active ones and the others are passive m...

Optimization of Hydraulic Engine Mounts through Simplified and Full Vehicle models

Optimization of engine mounts has been performed in several studies; some of them investigated single mount model, some studied mounted engine model, and others discussed on full-vehicle model. The goal of this study is to determine which model is more appropriate for the optimization of Hydraulic Engine Mounts (HEMs). A fullvehicle model is difficult to be modeled, and simulation of the model ...

Functional Overview of Hydraulic Vehicle Engine Mount Classification

Car design incorporates many engineering sciences where today, have led to the use of advanced technologies in automobiles to provide more satisfaction and comfort for the passengers, increase the quality of vehicles, efficiency and more pleasure than previous cars. These issues can be categorized into two groups in general. In the first group, the effects and performance of components involved...

A Study on Performance of Simplified Vehicle Models in Optimization of Hydraulic Engine Mounts in Comparison with Full-Vehicle Model

Grazing Bifurcations and Chaos of a Hydraulic Engine Mount

The constitutive relationships of the rubber materials that act as the main spring of a hydraulic engine mount are nonlinear. In addition to material induced nonlinearity, further nonlinearities may be introduced by mount geometry, turbulent fluid behavior, temperature, boundary conditions, decoupler action, and hysteretic behavior. In this research all influence the behavior of the system only...
