根据ＤＱ１０００／１５００．４５型斗轮堆取料机变幅装置设计制造了变幅试验装置，建立了三维梁元有限元模型，借助于有限元分析软件，利用子空间迭代法对模型进行了求解，得到其固有频率及相应的振型；对试验装置的动态特性进行了试验研究，测试结果验证了有限元建模和计算方法的正确性
A luffing test device was designed and manufactured according to the device of luffing of bucket wheel stacker and reclaimer of DQ1000 / 1500.45. The finite element model of three-dimensional beam element was established. With the aid of finite element analysis software, the subspace iteration method was used to solve the model. Get its natural frequency and the corresponding vibration mode; the dynamic characteristics of the experimental device were studied, the test results verify the accuracy of the finite element modeling and calculation methods
