Computer power drives GM Powertrain: virtual validation testing. (Manufacturing Technology).

GM Powertrain is harnessing another kind of power these days--the power of the computer. They're utilizing computer-aided engineering tools to simulate the validation testing processes of powertrain components and systems--a process that would normally have been done with hardware.

CAE testing not only improves function and performance, but by interfacing with the design process up front, there is a reduction in development cycle time and a dramatic savings In cost.

"The goal of synthesis and analysis," says John L Givens Jr., director of GM Powertrain Synthesis and Analysis, "is to produce first-time capable designs. We want to come out with a design that we know will meet requirements and then take it into a confirmation phase right offer the design phase."

Givens' 120 member team is divided into three functional sub-groups, …
