1. The document presents a finite element analysis of the universal joint of a Bharath Benz DE210BS4 engine.
2. The analysis examines the total deformation and equivalent stress on the universal joint at different working angles from 5 to 40 degrees and with different materials including steel, carbon fiber, AISI 4140, and SAE 1130 when subjected to torques of 450Nm, 1000Nm, and 35000Nm.
3. The results found that the carbon fiber material experienced the least total deformation and equivalent stress compared to the other materials tested, indicating it could be better suited for further development of universal joints.
