NOISE AND VIBRATION SOLUTIONS FOR

VIBRATION PROBLEMS ON HVAC SINCE 1969 Since 1969 AMC-MECANOCAUCHO has pioneered the manufacture and design of antivibration mountings for the reduction of vibrations in multiple applications. With this purpose, AMC-MECANOCAUCHO has developed a width range of products focused on the HVAC equipment isolation. These supports are manufactured using rubber, springs or a microcelular polyurethane material specially conceived for vibration isolation called Sylomer®.

AMC MECANOCAUCHO® PROCESS All machinery, which by virtue of its design has reciprocating or rotating parts, creates vibration to some degree through the imbalance of the moving parts. This vibration produced by a machine leads to different problems such as a reduction in the machine´s useful life through part wear plus the transmission of this vibration to other non-insulated adjacent structures, giving rise to problems of noise and vibration transmission. In this sense, AMC MECANOCAUCHO® has been developing for over 45 years different ranges of anti-vibration mounts that can solve problems like...

FATIGUE AND ENDURANCE TESTS AMC MECANOCAUCHO® has certificates of external laboratories that have tested our mounts to know the alteration of the stiffness properties during a representative life cycle of a an application. AMC MECANOCAUCHO® uses Instron Schenck® servohydraulic dynamic test benches to measure stiffness variation for mounts during a representative life cycle of an application. PROCESS CONTROL AMC-MECANOCAUCHO® realizes a process control of the mountings made manufactured. The % of sampling is according to customer requirement. On the graph below, stiffness values of a mount is...

1. Calculation AMC MECANOCAUCHO® calculates anti-vibration solutions by taking into account data such as weight, mount positions, type of machine, Center of Gravity, frequency of excitation, etc... One degree of freedom calculation Anti-vibration calculation with more than one degree of freedom. 2. Design After studying client specific needs for the application and the isolation performance required, AMC MECANOCAUCHO® can produce a new design if standard products are not suitable. Analysis of stress by non-linear FEM.

3. Test and dynamic characterisation AMC MECANOCAUCHO® can offer customers a wealth of experience and know how in measuring noise and vibration to effect optimun solutions to those problems. 4. Measurements AMC MECANOCAUCHO® provides its customers with all its experience and know-how in measuring vibrations and noise in the field so as to reduce machine-produced emissions of noise and vibrations.

NOISE AND VIBRATION SOLUTIONS FOR HVAC AMC MECANOCAUCHO® RANGE OF PRODUCTS FOR HVAC EQUIPMENTS These mounts work the rubber in shear and compression. Thanks to their section that produce large deflections, these BRB, BSB and DRD mounts achieve low natural frequencies and excellent vibration isolation values. Natural frequency: 5-11 Hz TYPE

The AMC-MECANOCAUCHO FZ mounts are composed by two metal parts surrounded by a high resiliency Sylomer® poliurethane compound that offers a high isolation capacity with a small static deformation in all MEDIUM-HIGH frequency range. They have also an interlocking metal component that provides a fail-safe protection. The Sylomer® polyurethane compound is oil resistant and the temperature range of the FZ mounts is -30ºC +70ºC. Natural frequency: 7-14 Hz Type

NOISE AND VIBRATION SOLUTIONS FOR HVAC VIBRABSORBER + The main characteristic of these mounts is their own capacity to isolate very low frequencies. A wide range of loads are covered with these spring mounts. A Sylomer® pad can be included under the base plate for all the VIBRABSORBER range improving the isolation, mainly at midhigh vibration frequencies that could be transmitted by the spring coil. MOUNTS (Natural frequency: 3-5 Hz) MOUNTS (Natural frequency: 2-5 Hz) These VSR + Sylomer® and VSH + Sylomer® mounts are manufactured using steel springs that can provide very high deflections up...

HANGERS SOLUTIONS These Spring type mounts are thought for ducts and air conditioning units that are set to ceilings. They have the same characteristics as the VIBRABSORBER spring range of mounts, isolating very low disturbing frequencies. Natural frequency: 3-5 Hz TYPE Natural frequency: 3 - 5 Hz TYPE Natural frequency: 3 - 11 Hz TYPE
