Analysis of Another Automotive Hydraulic Engine Mount

In the ADINA News Group Addendum, Analysis of Automotive Hydraulic Engine Mount (May 15, 2002), we presented an analysis of an automotive hydraulic engine mount.

This time, we present a simulation of a hydraulic engine mount of another design. As in the previous analysis, a sinusoidal displacement is applied to the top of the engine mount. The figure above shows first the solid mesh (blue) followed by the fluid mesh (yellow), and after this an animation of the deformation of the mount. The pressure in the fluid is also depicted in the animation.

The Z-(vertical) direction reaction-displacement curve is shown at right, demonstrating the phenomenon of hysteresis.
