Week 8 - Universal Joint

Objective: To perform a transient structural analysis on a double universal joint with a spring using three different materials: Structural Steel, Stainless Steel and Titanium alloy(They can all be found in the General Materials section) The three materials must be used on the joint with the springs alone. Use a refined mesh if possible for the academic license. You need to obtain the Equivalent stress and total deformation for all the three cases and compare them. Submit a report regarding the same.

Procedure:

in this analysis we will use structural steel as material for case1.stainless steel for joint with spring in case2.Titanium alloy for joint with spring in case3.

Material properties:

structural steel:

stainless steel:

Titanium alloy:

Create joints as fixed joint for spring.Revolute Body to ground and revolute body to body joints

The mesh used in the element size with 2mm

In analysis settings Number of steps are 5.Auto time step is off large deflection is to be on.weak springs are programme controlled and all out put controlls should be yes.the time step used in this simulation is 0.1 seconds for all 1 to 5 steps

Insert joint load for revolute body to ground joint

Results:

Case1:

total deformation:

Equivalent stress:

Case2:

total deformation:

Equivalent stress:

Case3:

total deformation:

Equivalent stress:

Result Comparisson:

	Total deformation(mm)	Equivalent stress(Mpa)
case1(structural steel)	38.637	1394.9
case2(stainless steel)	38.637	1351.4
case3(Titanium alloy)	38.637	686.26

Conclussion:

In this challenge we can conclude that total deformation produced by three materials is same.but more stress produced by structural steel followed by stainless steel and Titanium alloy
