Material Specific Product Design Analysis for Conditional Failures A Case Study

摘要

Rotary kiln support roller and shaft are located under the kiln, which is in contact with the kiln ring. In recent years, it is estimated that many roller shaft failure occurs due to continuous loading condition that prevails in the industries due to inevitable facts. The shaft is affected by high stresses with respect to kiln load on the roller. A thorough insight over literature reports that it can be avoided by proper design and supportive remedial measures of the roller and shaft well before manufacturing. In the present study, the analyses of roller and shaft have been done using Finite Element Method. The loading position is varied according to kiln ring and the support roller for the actual working condition. The load calculations and analysis of the shaft are done by analytical and finite element method respectively. The results are compared between the existing and the new design by changing design metrics and material prospects.
