Engineering service provider FEV has launched FEV Virtual Engine 23, an update of its simulation software for advanced powertrain dynamics analysis. In addition to a number of improvements for cranktrain analysis, FEV Virtual Engine 23 offers solutions for elastohydrodynamic (EHD) bearings as well as expanded 3D dynamic gear analysis.
“We have added important functionality to FEV Virtual Engine that allows significant test cell development work to be replaced by simulation,” explained professor Stefan Pischinger, president and CEO of the FEV Group. “Virtual Engine optimizes powertrain development through reliable prediction of dynamics and, thereby, effectively reduces the development time.”
Virtual Engine 23 includes a new analytical approach for the 3D dynamic simulation of gears. This approach includes a detailed tooth contact analysis with simultaneous consideration of the overall system dynamics in 3D space. As a result, the user receives detailed values for durability and NVH behavior for individual components. The results also include factors such as torsional stiffness and pressure, the condition of the oil film – including the influence of lubricant type and temperature – as well as gear rattle and whine. This enables the modeling effort and simulation time to be optimized in both the conceptual and the specification phase.
