| Popis: | Problem statement: In this study a comprehensive methodology for calculating load sharing in Roller-bearing contact was presented bas ed on the experimental stress-optical method of caustics and Photoelasticity. Approach: The theoretical equations describing the geometry o f transmitted caustic in relation to the length of th e contact zone were derived and a simple mathematical set of equations correlating the maxim um diameter of transmitted caustic with the magnitude of load was given.For this contact probl em, the basic theory of photoelasticity was given. Results: The techniques of caustics and photoelasticity were applied on a set of PMMA (Plexiglas) Roller-bearings and on a set of PCBA (L exan) Roller-bearings, respectively. Conclusion: The proposed method of the caustics is a reliable alternative for measuring load distribution in Roller-bearings compared to photoel asticity technique. |
