隔振层 meaning in English

vibration insulation

Then a simplified computational modal of damping isolation systems is established for a platform structure , and the relationships between the parameters of isolation layer and structural damping ratio , including their vibration - suppressed effect on the whole structure and the relative displacement of isolation layer are studied , and the simulation analysis under several representative load case of random wave force and earthquake affairs is performed . under random wave force , using complex mode theories , non - classically damp problems considering the interaction between the structure and wave , lying in deepwater , are studied . and the resolution solution of structural response are achieved . the results of calculating and analysing show that adding damping isolation to a jacket is an effective way to reduce vibration for offshore platforms
