3 SOLVING VIBRATION PROBLEMS ON HVAC SINCE 1969 Factory 1 Factory 2 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 in the HVAC equipment isolation. This supports are manufactured using rubber, springs or a microcelular polyurethane material specially conceived for vibration isolation called Sylomer. 3

4 NOISE AND VIBRATION 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 40 years different ranges of anti-vibration mounts that can solve problems like the ones described above. Taking into account some data of the machine such as weight, mount positions, type of machine, Center of Gravity, frequency of excitation, etc., AMC MECANOCAUCHO does vibration calculations in order to suggest the most appropriate anti-vibration mount solution for each case. The proposed solutions are commonly taken using following types of antivibration mounts: AMC BRB, AMC BSB and AMC DRD mounts (Rubber-Metal solution), AMC Vibrabsorber mounts (spring mounts solution), Sylomer and FZ+Sylomer mounts. QUALITY CONTROL AMC-MECANOCAUCHO is a ISO 9001 certified conpany by DET NORSKE VERITAS DNV. AMC- MECANOCAUCHO is officially approved by NATO under the id number NCAGE 0230B- compliant supplier. Rubber curing properties are controlled by Rheometrical instruments as well as extensometers, dynamometers and durometers. Elastical properties are measured with several axial and radial dynamometers as well as with a servohydraulic dynamic test bench from Instron-Schenck.

5 FATIGUE AND ENDURANCE TESTS AMC-MECANOCAUCHO has certificates of external laboratories that have tested gearbox mountings to know the alteration of the stiffness properties during a representative life cycle of a wind turbine. AMC-MECANOCAUCHO uses Instron Schenck servohydraulic dynamic test benches to measure stiffness variation for generator mountings during a representative life cycle of a wind turbine. PROCESS CONTROL AMC-MECANOCAUCHO realizes a process control of the mountings made manufactured. The % of sampling is according to customer requirement. On the graph beneath, stiffness values of a generator mount is shown while production is taking place. TRACEABILITY AMC-MECANOCAUCHO can keep track of the finished goods for those customers that require traceability on their products. Rheometrical tests are linked to each batch of production. This allows to verify the vulcanization properties of the rubber mix used. Foundry castings can incorporate the date of manufacturing. Finished goods can incorporate a serial number. This allows us to check stiffness values of the mounts as well as other complementary information. NOISE AND VIBRATION 5

17 FLOOR MOUNTS FZH + The goal of the system is to avoid the structure borne noise installing elastical mounts that are embedded in the concrete floating floor.the process of ele- vation is done once the concrete is dry. The AMC- MECANOCAUCHO type FZH mounts incorporate a polyurethane elastomer called Sylomer. This material offers optimal elastic and mechanical properties for the application. The AMC-MECANOCAUCHO type FZH mounts can be manufactured in different densities of Sylomer to match the natural frequency needed on the application. The process of leveling is simple and effective. The density of mount per m2 is1.12 and the distance between the mounts is 0,9m.

High insulation, anti-vibration characteristics thanks to the Sylomer and used in tacos, very low natural frequencies that provide optimum insulation are achieved.

19 ADVANTAGES NOISE AND VIBRATION LOW-LEVEL, optimum efficiency damped screeds without much height is achieved. Given that the available height is severely limited in many cases, the entire available height becomes concrete slab system and adding mass to lower the natural frequency getting. High insulation, anti-vibration characteristics thanks to the Sylomer and used in tacos, very low natural frequencies that provide optimum insulation are achieved. Quick installation without placing board or joints between boards. Economy, save assembly time, we do not need boards or tacos. Safety, avoid the appearance of acoustic bridges, as when lifting the slab we are 100% sure that there has been no error in making the slab. Easy and simple assembly, it does not take a specialist to perform this ground. DRAWINGS 19
