摘要

视钢球磨煤机为由端盖与筒体构成的回转体

截取壳体的 1/4 建立有限元计算模型

将不同重量的介质荷载等效移植到壳体单元上

通过有限元计算分析

得到了介质重量变化对钢球磨煤机端盖应力的影响数据。结果表明

随着介质重量的不断增加

端盖过渡圆角部位的相当应力值亦增加

其中 f点处的相当应力在各种介质重量工况下都为最大值;4种载荷情况下

交变应力的最大值均发生在f点

最大相当应力σfr3d 与介质重量之间可近似视为线性关系。

Abstract

Regarding the ball mill as a rotary body being composed of end covers and barrel shell

a finite element calculation model has been established by cutting 1/4 of the said shell

the medium loads of different weight being transplanted on elements of the shell. Through finiteelement analysis

the influencing data of medium weight variation upon end cover stress of the ball mill are obtained. Results show that the corresponding stress values at transition rounded corner of the end cover increase along with continuous increament of the medium weight. Among them

the corresponding stress at f point is the maximum under different medium weight conditions; Under four load conditions

the maximum alternating stress has been all occurred at f point

the relationship between max. corresponding strees δ f_ r3d and medium weight may be approximately regarded as a linear equation.
