Isolation Method<\/strong><\/h2>\n\n\n\n

2 stage system using Open Spring Mountings and MD\/3 Silicon Fluid filled Viscous Dampers between each generating set and a common intermediary steel support frame. The steel support frame is isolated from the main structure by Studflex Rubber Pads in a mixture of sizes and rubber compounds. The 2 stage system was then covered by an acoustic enclosure designed by Powerplus Engineering Ltd in Colchester, a company we have worked closely with on a number of projects.<\/p>\n\n\n\n

Performance<\/strong><\/h2>\n\n\n\n

The Arup Acoustics Specification called for Spring type isolators with a static deflection greater than 50mm fitted with ancillary dampers to prevent excessive movement as the machine passes the resonant frequency of the mounting system.<\/p>\n\n\n\n

10 No. OS75\/2000 Open Spring mountings (75mm deflection @ 2000kg) supporting 1511.6kg per mounting.<\/p>\n\n\n\n

56.7mm deflection achieved on each mounting giving an isolator natural frequency of 2.09Hz.<\/p>\n\n\n\n

Vertical Isolation Efficiency of 99.29% at 1500 RPM.<\/p>\n","protected":false},"excerpt":{"rendered":"
