Abstract:

The idler shaft is an important component part of shearer, and the stress distribution of idler shaft is worked out for Finite Element Analysis in the environment of ANSYS-Workbench after carrying on parametric modeling of shearer idler shaft. The relationship curve between all the parameters and maximum stress is worked out after changing the parameters of maximum stress effects on the sensitivity analysis. The idler shaft design is optimized using the curved surface from sensitivity analysis which makes the premise to meet the strength to reduce the weight of the idler shaft and cost savings.

Key words: Idler shaft, finite element analysis, stress distribution, sensitivity analysis
