目前,传动装置振动计算多采用集中参数法,未将轴系振动(扭转振动、横向振动与纵向振动)以及结构振动进行综合分析,与实际情况有一定的差别.本文以典型双机并车装置传动(包括柴油机、高弹性联轴器、万向轴、传动齿轮、主轴与输出负载)为研究对象,应用多体系统动力学理论对其激励特性进行研究,为传动装置有限元动力学响应分析提供输入条件.在完成传动装置多体动力学仿真分析的基础上建立传动装置有限元分析模型,然后对传动装置进行轴系振动和结构振动有限元动力学响应分析,并进行试验验证.同时,讨论转速和隔振刚度对传动装置结构振动的影响规律.最后,通过总结,初步形成船舶传动装置基于多体动力学和有限元仿真的振动特性预估方法,以完善和充实传动装置的研究方法和理论.%The lumped parameter method is widely adopted in the vibration calculation of the transmission system currently. The aggregate analysis of the torsional vibration of the shafting, the transverse vibration,the extensional vibration and the structural vibration are not undertaken. In this thesis,the drive characteristics are researched applied the theory of the multi-body dynamics and the input conditions are supplied to the dynamic response analysis of the finite element model based on typical two-engined joint operating device ( include diesel engine, the elasticity coupling, cardan shaft, driving gear, main shaft and output load). Through the dynamic simulation with transmission system,the finite element analysis model of the transmission shafting is established, and the dynamic responses of the shafting vibration and structural vibration are analyzed, and the experimental verification was proceeded. Meanwhile, the transmission characteristics of the structure vibration about transmission system are revealed. The influence regulations about the parameters of the elasticity couplings, rubber isolators to the structure vibration are discussed. Finally, through the analysis of the multi-body dynamics and the finite element dynamic responses, the simulation analysis method about the vibration of the transmission system is formed so as to perfect and enrich the research approach and theory of the transmission devices.
