FEV Virtual Engine 24.2: Dynamic simulation with extended functionality

FEV software allows high-precision coupled bearing analysis and efficient valve drive design.

FEV has launched a new release of its "FEV Virtual Engine” 3D powertrain dynamics simulation software. In addition to  optimized crankshaft analysis, version 24.2 offers significant enhancements for elastohydrodynamic (EHD) plain bearing simulation as well as an advanced dynamic 3D gear analysis.

With the new release, FEV have added important functionality to FEV Virtual Engine that allows significant test cell development work to be replaced by simulation. Virtual Engine enables rapid and reliable predictions of drivetrain dynamics, resulting in dramatic reductions in the required drive development time.

Since its introduction in 2008 the innovative, template-based FEV Virtual Engine software has combined the advantages of easy-to-use, special-purpose software with the performance of a universal, extensible dynamic simulation software tool.

Virtual Engine’s extensive modeling options enable not only the analysis of every component in conventional powertrain drive systems, but it also includes simulation of new and innovative alternative designs such as start / stop systems, hybrid drives, transmissions and drivelines.

EHD analysis with significantly enhanced performance

The analysis output has been extended with the inclusion of the plain bearing “filling level” simulation, which provides insight into the dynamic fluid and gas distribution. Additionally, instantaneous and accumulated wear indicators are now available in the Adams/PostProcessor and in the animation output.

Besides these functional improvements, the EHD analysis has been significantly accelerated by applying new measures including, among others, multi-threading.

Single valvetrain kinematics analysis for finger followers

The analysis of finger followers has been added to the kinematic analysis of the individual valve drive units. The purposeful interlocking of the program functions makes direct evaluation of the effect of changes in the valve lift curve on the kinematic cam contour possible. Forces and contact stresses can be determined automatically and displayed in the post processor. Through a software toggle setting, the kinematic model can be converted to a dynamic model for analysis in the time domain by simply switching it over to a new dynamic model.

In addition to these advanced analysis functions, the new release includes extensive improvements related to the crankshaft wizard, the crankshaft concept analysis, dynamic simulation of the piston / piston rings, and torsional vibration dampers.
