摘　　要：在大型减速齿轮装置的试验过程中,振动与噪声是试验过程的控制关键因素,其受到被测产品、陪试产品及试验台架振动指标影响。针对这个问题,采用有限元方法,对试验台系统进行了模态分析和谐响应分析,研究了试验系统各部套的模态频率和振型,分析了发生共振的可能性,并建立了试验台系统的扭转振动模型,对试验台的扭转振动特性进行了研究,分析了可能引起试验台系统发生扭转振动的因素,找到了试验台系统振动控制的最佳方案。研究表明:在设计初期就应用仿真技术对大型减速齿轮装置试验系统的振动进行分析与优化设计,能解决大型减速齿轮装置在实际运转中的振动与噪音问题,从而加快大型减速齿轮装置试验和开发的进程。In testing process of a large-size reduction gearbox test system,its vibration and noise are the key parameters used to estimate its performance,which are caused by the vibration of the test gearbox and the support saddles.In this paper,a new simulation method is proposed to analyze vibrations of a large-size reduction gearbox test system,which consists of a finite ele-ment （FE）method and a torsional vibration analysis method.In this method,the natural fre-quencies,the mode shape and the vibration response of the large-size reduction gearbox test system are studied using the FE method,and the factors of the resonance of the system are dis-cussed.Furthermore,a torsional vibration model of the large-size reduction gearbox test system is proposed to study the torsional vibration of the gearbox test system.Also,the factors of the torsional vibration are discussed.The simulation results show that the vibration analysis and the optimization design of the gearbox test system should be considered at the beginning of its design stage.The results also show that the proposed method can be used to improve the vibration and noise level of a large-size reduction gearbox test system.
