A Workflow Combining Ansys Sherlock, Icepak, and
Mechanical to Evaluate the Reliability of Electronic
Systems in Autonomous Vehicles
/ Workflow:
1. We will begin with model initiation within Sherlock. Sherlock allows for the rapid creation of models utilizing electronic computer-
aided design (ECAD) files and has important defeaturing options that assist in moving f rom ECAD to a computer-aided design (CAD)
model to a usable finite element analysis (FEA) or computational fluid dynamics (CFD) model.
This workflow shows how Ansys Sherlock, Ansys Icepak, Ansys HFSS and Ansys Mechanical can
be used to mitigate certain failure risks of printed circuit board assemblies (PCBA) within an
autonomous vehicle.
We will explain the workflow using a hypothetical project involving a printed circuit board
assembly (PCBA) mounted on top of a vehicle in an aluminum chassis within a larger housing. In
this outline, we will use the Intel Galileo board, an open-source PCBA.
Additional assumptions:
• Natural and forced air convection is investigated
• Driverless taxi application
• Vehicle is assumed to be on for approximately 15 hours per day, everyday
• Residential roads
• Frequent potholes
