摘要:

针对筒体与滚圈大面积多体接触及结构重复性强的特点,应用接触伪单元及子结构技术,建立了筒体与滚圈的多体接触模型,通过定义当量密度,将窑皮、扬料板等的重量引起的载荷自动转化到其作用区域的体积上,减小了载荷处理的工作量.筒体与滚圈多体接触问题数值计算的结果表明:档位段筒壳应力远大于筒节段筒壳应力,档位段筒壳的强度较弱,筒节段筒壳强度有一定富余.

Abstract:

Aiming at the characteristics of large-area multi-body contact and strong structural repeatability between cylinder and roller, the multi-body contact model of cylinder and roller is established by applying contact pseudo-unit and substructure technology, and the load caused by the weight of the kiln skin and lifting plate is automatically converted into the volume of its action area by defining the equivalent density, which reduces the workload of load processing. The numerical calculation results of the multi-body contact problem between the cylinder and the roller show that the pressure of the cylinder shell in the gear section is much greater than that of the cylinder shell of the cylinder segment, the strength of the cylinder shell of the gear section is weak, and the strength of the cylinder shell of the cylinder segment is somewhat surplus.
