TBM主轴承疲劳损伤及游隙演化
Study on Fatigue Damage and Clearance Evolution of TBM Main Bearing
摘要
Abstract
As a key core component of Tunnel Boring Machine(TBM),the main bearing plays the role of carrying and transferring loads.The damage of the main bearing will cause abnormal load distribution and reduce the service life of the main bearing.Based on Abaqus,the fatigue damage behavior of TBM main bearings under the condition of low speed and heavy load was simulated.In addition,the damage evolution law of the main bearing in the time domain and the space domain was studied.Then,the clearance evolution of the main bearing was predicted based on the fatigue damage model.The research results show that the damage risk of the raceway is greater than that of the roller,and the damage risk of the main pushing raceway is greater than that of the other two raceways.When the damage is below 0.3,the clearance of the main bearing increases slowly.And when the damage is above 0.3,the clearance of the main bearing increases rapidly.关键词
