Applications
The AMC-MECANOCAUCHO® Hydraulic mounts have been primarily designed as engine and operator cab isolator mounts in vehicular off highway and agricultural applications.
It is particularly interesting for those engines that operate on a variable rotating speed that must regularly pass the natural frequency of the system during its normal running. Examples of this may be engines of 1,2,3 or 4 cylinders used on construction or agricultural equipment.
It is also interesting for cabins where vibration isolation is for operator comfort purposes but also can provide stability when the cabin is submitted to transient shocks.
Advantages
AMC Hydraulic Mounts accomodate these requirements as the fluid cavity is divided into two chambers with a specific orifice between them so that motion of the elastomeric element causes fluid to flow from one chamber to the other thus dissipating energy and creating damping in the system . These mounts are particularly suitable for installations requiring good vibration isolation but still require motion control under transient shock inputs , or when operating close to the isolation systems resonant frequency
For good isolation, low damping is required. For motion control, high dampening is required. The Mecanocaucho® hydraulic mounts accommodate these conflicting requirements. The fluid cavity is divided into two chambers with an orifice in between, so that …
