It is very often that “just putting some rubber” to isolate structures creates an inefficient or even a vibration isolation problem, without taking into account the characteristics of the whole system: such as media environment and temperature, material stiffness adjusted to the application load, surface area, material transmissibility, as well as pad design techniques, like shape factor conformity. These are fundamental to a good anti-vibration material selection and consequent noise reduction.
Through experience in T&D applications, Amorim Cork Composites has implemented a priority 4 step system approach in analysis and treatment of “noisy” equipment. Our 4 step approach focuses on the need to control vibration before it reaches the tank structure (and therefore closer to the source of vibration), impeding that structural vibrations on the tank are transformed into airborne noise through the amplitude vibration of the tank walls acting as “speakers”. Typical noise reduction gains (cumulative gains) can also...
