NONLINEAR DYNAMIC BEHAVIOR OF VISCOELATIC TPANSMISSION BELT

The nonlinear dynamic responses of viscoelastic axially transmission beltsare investigated and the Kelvin viscoelastic differential constitutive model is employed tocharacterize the material property of belts. The generalized equation of motion is obtained for aviscoelatic axially transmission belts with geometric nonlinearity first, and then is reduced to bea set of second-order nonlinear ordinary differential equations by applying Galerkin's method.Finally, the effects of viscosity parameter and elastic parameter and the moving velocity of thebelts on the transient responses are investigated by the research of digital simulation.

矿用带式输送机传动滚筒结构有限元分析

采用有限元仿真方法对某型带式输送机传动滚筒进行静力学分析。首先采用UG建立传动滚筒的三维模型,对传动滚筒不同区域进行受力分析,将三维模型导入ANSYS Workbench中,划分网格,定义约束以及施加载荷并求解得到传动滚筒的应力云图,仿真结果显示传动滚筒结构设计合理,满足设计要求。
