摘要
基于冲蚀模型和SIEM磨损模型,文中建立针对散料颗粒与溜槽壁面滑动的磨损预测模型,利用滑动磨损试验标定模型参数,通过API接口嵌入EDEM软件,对比仿真与试验结果,验证所提出的磨损模型预测精度。面向溜槽转运散料过程,通过数值模拟预测溜槽磨损分布规律,优化转运溜槽耐磨结构设计。结果表明:导料板和台阶形仿生结构可有效提高溜槽耐磨性能。
In this paper,based on the erosion model and the SIEM wear model,a wear prediction model of bulk material particles sliding on the chute wall was established.The model parameters were calibrated through the sliding wear test,and the EDEM software was embedded through the API interface.The simulation results were compared with the test results,which verifies the prediction accuracy of the proposed wear model.For the bulk material transfer process,wear distribution laws of the transfer chute were predicted by numerical simulation,and the wear-resistant structure design of the transfer chute was optimized.The results show that the guide plate and the step-shaped bionic structure can effectively improve the wear resistance of the chute.
