Influence of elastic element parameters on stress distribution and reaction forces in shaft support systems of sawing cylinders

This study investigates the effect of elastic element thickness variation in combined shaft supports on stress distribution and reaction forces in sawing cylinder systems. Two computational models were developed: (1) with elastic element thickness at support A greater than or equal to support B ( A ≥ B ), and (2) with thickness at support B greater than or equal to support A ( B ≥ A ). The analysis demonstrates that variations in elastic element thickness significantly influence stress distribution and reaction forces in the system. When the thickness at support A exceeds that at support B, shaft stresses decrease from 198×10 6 to 112×10 6 Pa, while reaction force at support B decreases from 943.24 N to 918.02 N. Conversely, when the thickness at support B exceeds that at support A, stresses increase from 8.83×10 6 to 183×10 6 Pa, with reaction force at B increasing from 899.04 N to 931.19 N. The results show that optimizing elastic element parameters can significantly reduce operational stresses in shaft support systems.
