Multi-axis vibration decoupling

The degrees of freedom for elastic vehicle dynamics and chassis parts performing guidance functions must be particularly stiff and well-damped to ensure correct vehicle behavior and good roadholding. Degrees of freedom corresponding to preferred directions of vibration transfer channels and that have the highest influence on running noise as heard by passengers, need to be flexible at high frequency.

Hydraulic insulators can provide very high performance solutions to this need, particularly if damping is provided along two orthogonal directions.

Dual-material insulators form an attractive alternative to hydraulic insulators. These products offer high performance and economical solutions. A typical use is at attachment locations of a flexible axle to the body. The result is very significant differences between characteristics typically in the horizontal plane and along the vertical axis.
