Week 2 Railwheel and Track

Aim: To perform a helmet visor integrity test and asses whether the provided specimen is fit for Snell rating. Theory: The test is carried out by a shooting a high velocity projectile(polycarbonate pellet) at the visor(polycarbonate) and assessing the damage to the visor. Visor integrity test beds can shoot pellets at…

Aim: To perform a parametric study using 3 different values of thickness for the car body. Setup: Assign the material (Stainless Steel NL) to the car body and delete all computer generated contacts. Assign the thickness of the car body as Parametric and give it the value of 0.3. The thickness of the car body we use will…

Aim: To simulate a bullet penetrating into a bucket using 3 different non linear materials for the bucket and analyse their behaviour for the same velocity of bullet. Setup: We begin by assigning the bucket with a material for each case: Al 1100-O MAGNESIUM Steel 1006 We proceed to deleting any pre-existing contacts and…

Aim: Perform an explicit dynamics simulation to find out the Equivalent Stress, Total Deformation and also insert a User defined result to calculate the temperature of the body. You need to perform this for 2 cases. One will be with a cutting velocity of 20000mm/s and the other will be with a cutting velocity of 15000mm/s.…

Aim:  To rotate the worm so as to get to almost end of the half cut and get results for Equivalent stress, Equivalent elastic strain and the total deformation in the model. Setup: We begin by defining the contact, the face of the threaded portion of the worm gear and the face of the spur gear. Our next step is to…

Aim:  Perform the tension and torsion test on the specimen. For the tension test, displace one end of the specimen to 18mm while keeping the other fixed. You will need to find out the total deformation, equivalent stress and temperature of the specimen. For the torsion test, you will need to displace one end of the…

Aim:  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 on the spring section to obtain the Equivalent stress and total deformation for all the three cases and compare them. Setup: Assigning…

Aim: Using Transient Analysis find the difference in deformation, stress developed and strain generated for the model using frictionless, Frictional Coefficient 0.1 and 0.2 contacts. The material being used for this simulation is structural steel. We begin by flipping the target and contact of the assembly in connections…

Aim: In this simulation we will be looking in detail at the stress and strain generated in an IPhone as it is bent as well as the deformation and the same values for a different position of application of force. We begin the simulation by inspecting the geometry in space claim and reducing the number of faces on the fingers…

Aim : To capture the plastic deformation experienced by a flat plate of Non-Linear Structural Steel when a sphere of Structural Steel is pressed down on it. Setup: We begin by establishing symmetry along both X&Z axes and manually establishing the contact parameters between the Sphere and the Plate. The contact is…

Aim: To evaluate the stress and strain generated on three different wires of the same dimensions and different material (Cu Alloy, Al Alloy, Mg Alloy). Pre-Processing We begin the simulation by importing the CAD model to space claim and checking for any imperfections before we proceed to open the mechanical module. Our…

Aim: In this simulation we will be looking at the stress and plastic strain developed in a copper slab as it undergoes rolling. We will also be looking at the change in width as well as the distance travelled by the piece. Setup: We begin by assigning the workpiece as Copper Alloy Non-linear and redefining the contact…

Aim: To study and perform structural analysis on a Sheet Metal with different material and frictional coefficient .Grid dependency test was also performed to optimize the element size for better accuracy Case 1: Aluminium Alloy 1199,Copper Alloy NL and Magnesium Alloy NL. Case 2: With the material as Aluminium Alloy, change…

Verification of Weld Joints In this simulation we will be assigning Stainless Steel, Aluminum Alloy and Bronze as the welding material with the plates and ribs being Stainless Steel, Stainless Steel and Stainless Steel(Plates) and Copper(ribs) respectively. A load of 15000N is applied on the small plate through the hole.…

Rail Wheel and Track We will be simulating the motion of a rail wheel on a track in this exercise to find the deformation on the wheel, Equivalent Stress generated across the system and the fatigue generated in the wheel and it’s subsequent Life Expectancy. The model is imported to and opened in space claim where…

Grid Dependency Test Mesh Size and Refinement is one of the most important considerations taken during Finite Element Analysis and the quality of Mesh depends on it. It directly effects the accuracy of any simulation, the higher the mesh density(or lower the mesh size) the higher the accuracy of the results. This would…

Objective: Using Cast Iron(ductile), Cast Steel and Bronze, Cast as a material, carry out a static structural analysis to find out Equivalent stress, Total deformation and Stress intensity   Setup:   Using the Model we distinguish the contact regions on both gears. distinguishing both gears as revolute joints to ground,…

Objective: To analyse and differentiate between 2 designs, Plate with Hole and Plate with Multiple Holes, on the basis of deformation and stress and choose between the 2 based on ease of manufacturing. Setup:While fixing one of the faces of the plate to a fixed support, we have applied a tension force of 500N on the opposite…
