摘要
避免柴油发动机的激励频率与其固有频率相接近或重合而产生共振,引起额外的噪声和联接件的振动或疲劳损坏。运用公司内部软件WinRemo对其弹性基座系统的静、动态响应进行了分析。案例以瓦锡兰W6L32机型为研究对象,通过计算选取、布置弹性元件,结合机组、主机、螺旋桨等参数来设计其单自由度弹性基座系统,并通过测量加以验证。试验表明:基于WinRemo计算的弹性基座系统,结合模态振型和刚体的静态、动态特性分析,能很好地隔离发动机的激励,能有效地降低发动机的振动、噪声,是一种简单、稳健的计算方法。
To aviod the excitation coincides with its natural frequencies from diesel engine,resulting resonance causes extra noise,vibration and strain failure on components connected to the engine.This article calculates static and dynamic responses of a resilient mounting system using WinRemo,the company Wartsilas internal software.Taking Wartsila W6L32gen-sets as an example,elastic components are selected and deployed based on computation.A single degree of freedom system for resilient mounting is designed based on parameters of the main engine,gen-set,and propeller.Finally,The system is verified by measurement.The results show that integrating mode analysis with static response and dynamics response with WinReMo can well isolate excitation and effectively attenuated vibration and noise.It is a simple and robust method.
