Abstract


With development of the modern industrial technology, the project of vibration noise issues in modern industrial fields is becoming an increasingly prominent problem. This issue was based on the university science and technology plan projects of Shandong province (J06F53) which is the impact of Architectural environment by aero source power units and the research of double vibration isolation system. Community management center 202 pump room noise control engineering of Yankuang Group. Double isolation technology of the Power unit. Mainly is aims at the heat pump unit floating raft isolation stand more than that, through the system disturbance source establishing its system power flow transfer model, this paper analyzes the influence of spatial pipe floating raft isolation system transmission characteristics of power flow, and the impact the floating raft isolation system vibration isolation efficiency factors, discusses the features of a floating raft device, which focuses on the research space layout of the pipe and rigidity, especially song of the power unit of soft takeover flexible isolation performance and stability influence; Discusses the pump unit isolation design technology and in order to improve the performance of vibration isolation and certain aspects of should be paid attention to.The floating raft isolation technology is a kind of effective antivibration noise reduction technology, it can restrain the vibration of the hull from machine to transfer, related theory and test research has also become the isolation technology research hot spot. For the domestic and foreign scholars, the dynamic performance of vibration response had already done a lot of work. The study involved more than comparison of the naval war, but still comparatively rare in civil aspects in engineering practical applications, at present, there are also many theoretical problems remain to be solved.This subject based on heat exchange station pump unit of antivibration noise reduction floating raft isolation system for the basic research system transfer performance of power flow, floating raft isolation system analysis on factors of vibration isolation efficiency, this paper discusses the characteristics of floating raft device, which has certain theoretical level research and practical application value. The main contents include:establish a floating raft isolation system unit dynamic model; The symmetric structure is established more units floating raft isolation system optimization model, use of Matlab simulation; The monomer of symmetrical structure floating raft isolation system optimization design; And floating raft isolation system of monomer isolation efficiency was tested.
