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。
During the test of a large reduction gear unit, vibration and noise are the key factors in the control of the test process. They are affected by the vibration indexes of the product under test, the test sample and the test bench. In response to this problem, the finite element method is used to analyze the modal analysis and harmonic response of the test bench system. The modal frequencies and mode shapes of the test systems are studied. The possibility of resonance is analyzed. A test bench system The torsional vibration model of the test bed is studied. The factors which may cause the torsional vibration of the test bed system are analyzed, and the best solution to the vibration control of the test bed system is found out. The research shows that in the early stage of design, the simulation technology is applied to analyze and optimize the vibration of the test system of a large reduction gear device, which can solve the vibration and noise problems of the large reduction gear device in practical operation and accelerate the test and development of a large reduction gear device The process.
