中文摘要	针对回转窑托轮偏斜对接触区应力分布的影响,运用赫兹接触理论,推导出托轮与滚圈最大接触应力比与托轮偏斜角的关系;采用有限元方法计算某支承结构托轮平行与呈最大偏斜角时的接触问题,得到支承部件接触应力和等效应力应变分布情况,并得出滚圈和托轮的危险易损部位;为回转窑的轴向调控提供了有效的理论依据。; Because of the influence of rotary kiln supporting wheel's deflection on the contact area' s contact stress,according to Hertz contact theory,the relative among deflection angle,the maximum contact stress and maximum contact stress ratio when supporting wheel is under parallel and deflective are derived.Furthermore, with the finite element method,the contact problems when supporting wheel is under parallel and the maximum de- flection angle state are solved.Distribution of supporting parts' maximum contact stress and the equivalent stress and strain are obtained,and the dangerous and damageable place is learned.These analysis conclusions can pro- vide effective theoretic guidance for rotary kiln axial adjusting and controlling.; 国家自然科学基金(50675066); 中国博士后科学基金一等资助项目(2005038006)
