【摘要】 以ＤＱ １０００／１５００·４５型斗轮堆取料机变幅装置为研究对象，建立了其三维梁有限元模型，分析了 系统运动方程的建立和求解过程。借助ＳＵＰＥＲＳＡＰ９１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。更多还原

【Abstract】 With the derrick mechanism of bucket wheel stacker model DQ1000/ 1500.45 as objective, a finite element model of 3D beam is established and the set-up and solving procedure of system’s kinematic equations are analyzed. System’s natural frequency and corresponding mode of vibration are solved by way of sub-space iteration with the aid of SUPERSAP 91 software.更多还原
