Powertrain Simulation and Analysis Speeds Development

Although FEV Virtual Engine software has been available since just 2008, FEV (fev.com) recently launched the 23rd version of the simulation software for advanced powertrain dynamics analysis.

This undoubtedly has to do with the rapid advances that are being made in powertrain technology, and underlining that point, Mustafa Duyar, product business manager for the product says, “The extensive modeling options of FEV Virtual Engine not only facilitate the analysis of every part of conventional powertrain systems, but also of new and innovative designs—for example, from belt-driven start/stop systems up to complete hybrid drives.”

What’s more, according to Prof. Stefan Pischinger, president and CEO of FEV Group, the software can actually minimize the requirement of hardware in powertrain development: “With the new release, we have added important functionality to FEV Virtual Engine that allows significant test cell development work to be replaced by simulation.”

One of the areas where the new release has been improved is in the analysis of gears. The 3D dynamic simulation of gears includes detailed tooth contact analysis with a simultaneous consideration or overall systems dynamics. And the level of detail is such that there are values for the durability and NVH behavior of individual components. Torsional stiffness and pressure are detailed, as is the condition of the oil film. Gear rattle and whine are also simulated.

In addition to which, the FEV simulation software also has solutions for elastohydrodynamic (EHD) bearings.

Pischinger says, “Virtual Engine optimizes powertrain development through reliable prediction of dynamics and, thereby, effectively reduces development time.”
