基于响应面法的多因素交互作用下中部槽磨损试验研究

摘要/Abstract

摘要： 为确定影响中部槽磨损的主要因素及交互作用关系，通过中部槽磨损试验，以磨损量为响应值，基于响应面法进行了磨损因素分析。通过Plackett-Burman试验对6个磨损因素进行筛选，发现煤散料含水率、煤散料含矸率及法向载荷对磨损量影响显著。根据中心复合设计(CCD)试验结果建立了磨损量与显著性因素的二阶回归模型，经响应面分析可知，散料含水率是影响磨损的关键因素。对回归模型进行优化，得到显著性对磨损量的预测模型，经试验发现预测模型与真实试验无显著差异(P>0.05)，表明应用响应面法进行中部槽磨损多因素交互作用研究是可行的。

Abstract: In order to confirm the main factors affecting wear of middle plates and interaction relationship, the wear factors were analyzed through wear test based on response surface method with the wear loss as response values. The Plackett-Burman test was used to screen the main factors from the six wear factors. Results show that water content, gangue content and normal load have significant effects on wear loss. According to the results of central composite design (CCD) test, the second-order regression model was established based on the wear loss and significant factors. Response surface analyses show that the water content of bulk materials is the key factor affecting wear. The regression model was optimized to obtain a significant prediction model of wear. The results show that there is no significant difference between the prediction model and the real test (P> 0.05), which indicates that the response surface method is feasible to study the interaction of multiple factors in chute wear.
