Work Experience

CAE Modeler
From Oct18 – Present
Company profile - leading engineering service provider to the automotive industry

Job profile -
Understand the Project Scope, time estimation, planning, initiation, execution and delivery of projects in accordance with the customer requirements
Check for CAD intersections and FE modeling as per given quality criteria, assigning thickness and material properties, removing penetrations, connections carried out (NVH & DURA)
System level connections for major modules like BIW, Front and Rear Bumper, Closures. Establishing Bolt, Seam weld, Spot-weld, Mastic, Weather-strip, gas-strut, wedges and adhesive connection in FE.
Non-structural mass creation, section force creation at the required location at the required region for Nastran solver deck using Hyper mesh and ANSA.

PROJECTS
Model analysis for Closures
Run the model after completing the proper check like (free, Duplicate, Nastran  Dependency, Model data error and Nastran loop)  
Opti checking for element Quality of model. (.out file)  
Check normal modes in HYPER VIEW  
To identify the unconnected parts and their connections  
To ensure the rigid body modes  

Body-In-Prime integration for Durability/NVH 
Project involves Body-in-prime development of Car, bus and van models for various milestones across FNA region.  
Gauge and grade modifications are done referring to EBOM (Engineering Bill of Materials)
Bolt Connection for Sheet metal parts, structural GOR / Bolster, Sub frame, Mounts, tunnel brace and bumpers done with C-bar dia representing the actual fastener size. 
De-penetration activity is carried out for dura and the model is cleared for 90% contact thickness.  
Modelling of Hangers using Tetra/ hexa then connecting to BIW with rigid elements. 
Spot-weld connections represented as RBE3-hexa-RBE3 (ACM2) based on client input file.  Debugging of spot-welds done for connectivity. 
For Dura, Seam weld and laser weld are modelled as shell elements based on guidelines with consideration for Weld type, Weld Leg width and orientation and Weld thickness. 
Glass bonding, structural adhesive, mastic, anti-flutter represented as ACM2 connections with properties based on
guidelines.  
BIP weight to be summarized and compared against legacy. 

Closure Connections for Durability/NVH 
Meshed Structural panels are checked against the input cad for consistency and compatibility with BIW Is checked before proceeding with connection activities. 
Hemming done as node-to-node pasting on outer and inner panels based on client requirements. 
Primary and secondary weather seals, glass runs and beltlines are represented as spring elements with suggested stiffness values from the client.  
Latch locations are modelled are rigid elements with spring to represent the latch stiffness.  Local Co-ordinate System is used to set the CBush properties at desired direction. Door hinge parts are modelled as Chexa elements with hinge pin as CBar. To facilitate the swing motion of the door, J value of Cbar is set to 0.  
Gas struts for lift gate were modelled as 1D elements with DOF set to facilitate ball joints.  Stiffness is based on Program specific data. 

Sheet metal and solid meshing for Durability/NVH 
Meshing for various automobile parts contributing to Body-in-prime and closures has been carried out.  
Model downloaded from Team center client is delegated to the meshing team. Work estimation for the same will be done and communicated to the team.  
Responsible to review the meshed components against customer guidelines.
Proper checks done based on Lessons Learnt document to meet the FE mesh quality requirement.
