AMC MECANOCAUCHO • Anti-Vibration & Noise Control

AMC Mecanocaucho — Vibration & Noise Control for Marine and Industrial Applications

Vibration generated by engines, generators and auxiliary equipment can gradually stress connection elements, increase cabin noise and reduce onboard comfort. Since 1969, AMC-Mecanocaucho has been manufacturing anti-vibration mounts and rubber-to-metal bonded components. Its product range includes a wide variety of solutions such as marine engine mounts, failsafe mounts, acoustic hangers and sound insulation foams.

What Does the AMC Approach Provide in Practice?

The goal is to reduce the transmission of vibration to the hull or chassis by damping it at the source. This can improve comfort while also reducing fatigue loads on connection elements and equipment. AMC’s anti-vibration product group clearly focuses on providing solutions for noise and vibration transmission problems.

Correct installation in marine applications

  • Marine mounts are recommended to be installed in a vertical position; angled installation may create static radial load and reduce isolation performance.
  • Mounting direction and stroke limits directly affect the real working character of the mount.
  • After installation, vibration behaviour should be checked and stiffness selection should be revised if necessary.

The “pipe-line” effect in noise transmission

  • On vessels, noise is often transmitted through exhaust and piping systems.
  • AMC states that elastically suspending the exhaust system can, in some applications, be the only solution to reduce noise and vibration propagation.
  • For this reason, not only engine mounts but also line suspension points should be planned together.

Solution Groups

AMC-Mecanocaucho has a very broad product range. The headings below summarize the most common needs in marine applications with a practical “what it does” approach.

Marine Engine Mounts General Series

Mount

AMC marine engine mounts are described with an emphasis on rugged architecture for mobile applications. The design is stated to aim for improved vibration isolation through suitable stiffness values in different axes and high vertical elasticity.

PurposeVibration isolation
FocusMulti-axis behaviour
ScenarioEngine / generator

MARINE MOUNT XT Captive

Marine

MARINE XT captive mounts are described as a structure in which rubber works in both shear and compression. They are designed to provide different stiffness values in each axis and contribute to lowering the roll natural frequency in engine installations.

TypeCaptive mount
FeatureAxis-based stiffness
FocusEngine installations

MARINE MOUNT XD

Marine

XD Marine mounts are positioned for mobile applications that require a higher degree of isolation. They are described with the goal of providing better isolation in demanding conditions.

FocusHigh isolation
ScenarioMobile equipment
NoteMounting direction is critical

Marine Exhaust Mounts

Exhaust

Part of the noise on a vessel is transmitted through exhaust and piping systems. AMC emphasizes that elastically suspending the exhaust system can be an important solution for reducing vibration and noise propagation.

PurposeReduce line vibration
ScenarioExhaust / piping
CriticalSuspension points

Anti-Vibration Mounts General Series

AV

Vibration isolation can also be critical in auxiliary equipment such as pumps and compressors, not only in engines and generators. AMC anti-vibration mounts are designed to provide solutions for vibration and noise transmission problems.

ApplicationAuxiliary equipment
FocusNoise & vibration
SelectionLoad / RPM / axis

Installation Note: Vertical Mounting for Marine Mounts

Tip

AMC recommends installing marine mounts in a vertical position. In angled installation, equipment weight can create radial load; this may cause the inner bushing to approach the end of stroke, increase stiffness and reduce isolation.

RecommendationVertical mounting
RiskStatic radial load
EffectIsolation may decrease

Correct Selection and Application with Akel Marin

Selecting a mount only by “model” is often misleading. First, we evaluate equipment operating data such as RPM, weight and shock loads, together with mounting direction and line connections, especially exhaust and piping. Then we select the solution with the right stiffness and commission it with the correct installation layout.

Frequently Asked Questions

  • There is vibration, but where does it come from? Exhaust and piping lines can transmit vibration as much as engine mounts.
  • Most common mistake? Installing a “similar product” without load and axis calculation.
  • What is checked after installation? Vibration behaviour at operating RPM, movement allowance and connection points.

Checklist for Correct Selection

  • Equipment: Weight, RPM and operating temperature.
  • Installation: Vertical / angled mounting and stroke allowance.
  • Lines: Exhaust and piping suspension points.
  • Target: Comfort, stability or shock resistance?
