摘要
回转窑是对固体物料进行机械、物理或化学处理的超大型筒体设备,在建材、冶金、化工等行业广泛使用。回转窑运行时工况复杂,在运行过程中筒体轴线会偏离理论轴线,导致各部件受力不均,各运动部件磨损加剧、寿命缩短,进而引发一系列问题。首先对某大型回转窑模型进行有限元分析,然后在回转窑满足各部件受力均衡及筒体轴线直线度要求的前提下,以各档位之间的间距、滚圈变形的初始值、调窑量和支承角为设计变量,对回转窑进行等载同轴优化,最后通过计算结果数据建立二次多项式响应面模型,得出设计变量中各因子对结果的影响程度的大小,同时也得到了托轮在垂直和水平方向受力响应面模型的数学表达式。
The rotary kiln is a super large cylinder equipment which can apply mechanical, physical or chemical treatment to solid materials, which is widely used in building materials, metallurgy, chemical and the other industries. The rotary kiln works in the complex conditions. In the working conditions, the rotary kiln shell axis offsets the theory axis which leads to the problems such as unevenly stress, wearing aggravation, and life shortening and so on of some components. First, the rotary kiln model was simulated and calculated though finite element analysis. Then, to satisfy the aim that each component force being balance and the cylinder axis being straight simultaneously, taking the spacing between the various stalls, initial value, adjustment of rotary kiln and support the influence degree to the result of design variables was obtained. After the calculation, the mathematical expressions of vertical and horizontal stress response surface models for roller were obtained.
