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。

Identification of abnormal operating conditions and intelligent decision system

In earth pressure balance (EPB) shield construction, the “plastic flow state” is difficult to form using the soil dug in the capsule because it can cause three abnormal operating conditions, including occlusion, caking in the capsule, and spewing at the outlet of the dump device. These abnormal operating conditions can, in turn, trigger failure in tunneling, cutter-device damage, and even catastrophic incidents, such as ground settlement. This present paper effectively integrates the mechanism of abnormal operating conditions and knowledge of soil conditioning, and establishes a uniform model of identifying abnormal conditions and intelligent decision support system based on the belief rule-base system. The model maximizes knowledge in improving the soil, construction experience, and data to optimize the model online. Finally, a numerical simulation with specific construction data is presented to illustrate the effectiveness of the algorithm.
