【摘要】 采用参数化建模方法建立带式输送机驱动装置机架的有限元模型,对机架进行固有特性计算及强迫振动分析,计算出机架在工作时的振幅,通过对振幅曲线的分析,确定液力耦合器与机架的连接处为振动过大的位置,据此对机架结构进行改进设计。更多还原

【Abstract】 A parameterized modeling method is adopted to establish the finite element model of belt conveyor drive frame. First of all,natural features of the rack is calculated. Forced vibration analysis was carried out on the rack,to calculate the amplitude of the rack on the job. By analyzing the amplitude curves,determine the position of frame vibration. On this basis,the design of frame structure is improved.更多还原
