Based on your interest, you can start working on the above domains.


Simulation of Roof Crush on Dodge Neon BIW Using HyperWorks Radioss

In this project, you will Import the car model and an impactor. Then the model needs to be transformed along various directions and the mesh is cleaned up for any free nodes and elements using HyperMesh. Proper contact is defined for the interface between the bodies. Finally, after running the simulation, the solution is post-processed, checked for any errors in HyperCrash and the results are validated against FMVSS 216 TARGET (3*GVW) by Crossing-plotting the Force-Time and Displacement graph.

Simulation of Side Pole impact test on a Dodge Neon BIW using Hyperworks Radioss

In this project, after importing the model, the mesh is cleaned up for any errors. The interface is defined between the impacting bodies. Various mass loads are added to balance the center of gravity and the simulation is set up to run using Radioss. The output results are then post-processed and the intrusion into the B-Pillar, Hinge pillar, and the fuel tank are measured in Hyperview. Finally, recommendations are made to reduce fuel tank intrusions.

Simulation of Full Frontal Crash Analysis of Neon BIW using Hyperworks Radioss

In this project, the simulation is set up by creating a rigid wall for the model to impact on. Mass balancing is done to achieve a target load of 700kgs and GC at a specified coordinate. Finally, the simulation is run and post-processed in HyperCrash. Various output results like axial forces on the rails from the bumper, shotgun cross-sectional forces are studied.

Working on HyperMesh

HyperMesh is one of the most populat Finite Element Preprocessor used to generate meshes of complex model.

  • Geometry pre-processing
  • Mesh creation
  • Mesh quality and diagnostics

Working on HyperCrash

HyperCrash is a pre-processor for Radioss which is tailored to meet the needs of a crash users.

  • Mesh editing

  • Contact modelling
  • Initial and Bounday conditions
  • Manage mass and intertia peroperties of each and every part

Working on HyperGraph and HyperView

HyperGraph & HyperView, both are post processing tools in the HyperWorks Package. HyperView is a visualization environment for Multi-Body Systmes while HyperGraph can be used for evaluation of thousands of graphs without losing the overview

  • Extract key information from the simulation
    • You will be using Plot Builder to create annotated plots directly from engineering simulation.
    • Hyperview provides the flexibility to perform Curve fitting, Eigen system analysis, Injury functions and user defined math functions
  • Compare simulation results with experimental data
    • With Hyperview, you can create deformation plots and animations
    • We will be post processing the data that we generate through Radioss
