Transient Structural Analysis on a Double Universal Joint with a Spring Using Three Different Materials in ANSYS Workbench

Objective: Perform a transient structural analysis on a double universal joint with a spring using three different materials: Structural Steel, Stainless Steel, and Titanium alloy.

Model:

Material:

Structural Steel also called as High Strength Low Alloy (HSLA) steels have a typically small difference between yield strength and tensile strength (<100 MPa). They, therefore,

offer excellent bendability. With little pearlite and no other hard phases they also have better fine blanking properties compared to DP steels and due to lean composition, they are very easy to weld.

Stainless Steel also called as martensitic steel Martensitic (M) steels have very high yield strength (Re)and an extremely high tensile strength (Rm). Docol®martensitic steel has quite good draw ability and good edge stretching properties. It is also good in welding.

Titanium Alloy: Titanium alloys possess high specific properties, have a good fatigue strength/tensile strength ratio with a distinct fatigue limit, and have some retain considerable

strength at temperatures up to 400 to 500°C. Generally, there is also good resistance to corrosion and corrosion fatigue, although properties are adversely affected by exposure to

temperature and stress in a salt environment.

Results & Conclusion:

	Case 1 (Structural Steel)	Case 2 (Stainless Steel)	Case 3 (Titanium Alloy)
Deformation (mm)	38.6	38.6	38.6
Stress (MPa)	1355	1312.8	666.83

There not much difference in stress values in steel but in titanium the stress value is half as compared to steel because of its high tensile strength even retain considerable strength at temperature up to 400 to 500 deg cel.
