|
摘要
对钢丝绳芯橡胶输送带动态特性进行分析与研究是研发绿色节能带式输送机的关键,基于空间坐标变换理论建立钢丝绳芯橡胶输送带数学模型,在此基础上,利用Pro/E参数化建模及扫描、拉伸特征建立输送带三维细观虚拟仿真模型,分别以Ansys中Moonery-Rivlin模型和Bilinear Isotropic定义橡胶覆盖层和钢丝绳属性,设置钢丝绳与橡胶间的界面为固连接触,模拟了正弦载荷作用下钢丝绳芯橡胶输送带动态特性,研究结果表明:轴向位移载荷作用下,钢丝绳芯股轴向变形沿钢丝截面呈层状分布趋势;侧股侧丝轴向变形呈空间二次螺旋线变化分布;各侧股变形量基本相同且侧股中侧丝轴向变形量沿旋向逐渐增大,侧股相对芯股而言轴向变形量更为显著;橡胶覆盖层轴向变形量呈现中间变形量小,四周变形量大的趋势;橡胶轴向平均变形量远大于钢丝绳变形量。研究结果为钢丝绳输送带的结构设计与优化提供参考。
It is the key for the development of green energy-saving belt conveyor to analysis and research on the rubber conveyor belt of steel core about its dynamic characteristics. Mathematical model of the rubber conveyor belt of steel core were established based on the space coordinate transformation theory. Then 3-D microscopic virtual simulation model were established by using parametric modeling, scanning and tensile of Pro/E software. The Moonery-Rivlin and Bilinear Isotropic model of ANSYS were used to define attribute about rubber covering and wire rope. Simulated dynamic characteristics of rubber conveyor belt of steel core under sinusoidal pressure by setting tied between wire rope and rubber covering. The result show that, under the axial displace load, the axial deformation of steel core presented layered distribution trend along wire rope section. The axial deformation of side strand's side wire presented two-time-helix change distribution. Every side strand deformation amount was almost same and axial deformation of side strand's side wire gradually enlarged along handed, the axial deformation amount of side strand changed remarkably relative to Core strand. The axial deformation amount of rubber covering exist little deformation amount in the middle port and large deformation amount all around. The average axial deformation of rubber is larger than the deformation amount of wire rope. which reveal mechanism of energy consumption about rubber conveyor belt of steel core, then that provide theoretical basis for research and development of green energy-saving belt conveyor.
