Assignment 4

                                                               ASSIGNMENT-5 comparing the base setups simulation results and differant kinematic condition simulation…

Assignment 4   OBJECTIVE :-We have to Compare 7 cases as discussed in last 3 slides, in a tabulated format on the basis of:1. Total number of cycles, Energy error, mass error and simulation time.2. Notice the animation of all 5 and describe the animations in brief on thebasis of whether the elements are being deleted…

Objective: Comparison of results with base simulation and improved shell element properties.   Case 1 setup and Procedure: below details are the model with out any modification of crash beam , 1.Using the crash beam file from the previous assignment, we changed the run time to 55 ms.   Changing the number of…

ASSIGNMENT 2   Objective of this assignment. Checking the material properties of the rail component and to caluculate speed of sound in steel rail. calculate the time takes for a shock wave to travel from one end of the rail to the other. Time for sound to travel length of rail Editing the engine…

Objective of this task To carry out 2D meshing of this 3 parts.   Steps to carry out task Initially I import hm model in hypermesh 17. Carried out geometry clean up using options like F11 –fillet surface, unslit surface, toggle edges etc After geometry clean-up ,extraction of mid-surface using –Geom –midsurface…

Crash Box simulation  Here are the different assumptions : The crashbox should crash into a rigidwal. Material for the crashbox is steel Initial velocity for the crashbox should be around 50 kmph=13.88mmpms. The units system to be used is gm-mm-ms   Aim:To create a complete simulation file from this to perform…

Drop test Challenge    Aim: To create a complete simulation file from this to perform a drop test. Procedure: For the given FE mesh ,we going to assign materials as follow For Ground MAT20 RIGID assigned ,      RO=7.83e-6,E=207,PR=0.3 For Mobile and skin I assigned MAT24 PIECEWISE_LINEAR_PLASTICITY,…
