In developing new and improved engines, engineers often face conflicting design goals. They are challenged to reduce engine emissions and fuel consumption, yet deliver engines with more power, reduced vibrations, an optimal sound and maintenance free operation. LMS Virtual.Lab Powertrain Motion is a complete and integrated solution to simulate the complex dynamic performance of engines, and to accurately predict internal loads. These loads are needed to determine fatigue life, vibrations, and engine acoustic sound. Using virtual simulation, engineers can quickly identify the most promising concepts in developing new engine concepts, such as cam phasers, variable valve-lift devices and variable compression-ratio engines. Virtual.Lab Powertrain also supports engineers investigating shaft whirl, chain noise, gear rattle, and torsional vibrations in order to optimize the dynamics of driveline systems.
LMS Virtual.Lab Powertrain Motion offers dedicated powertrain modeling templates that help users to quickly build detailed models of full powertrain assemblies or specific sub-assemblies like valvetrain, cranktrain, driveline, timing chain and belt drive systems. Separately created sub-mechanisms can easily be joined together to study coupled behavior. The powertrain template generates fully parameterized models enabling fast modifications and an accelerated analysis of alternative designs.
Once the virtual prototype model is built, the Virtual.lab Motion Solver handles a broad range of powertrain applications:
- Valvetrain: simulate high order/high speed effects including spring surge, cam-contact design, or valve seating performance
- Cranktrain: analyze crankshaft and engine block interactions, bearing loads, crankshaft vibrations and dynamic stresses
- Driveline: analyze prop shaft bending and whirl, garage clunk and shift clunk, or driveline booming
- Timing Chain: quick layout and dynamic simulation of complicated sprocket, guide, and chain configurations
