Powertrain Motion

When developing new and improved engines, engineers often face conflicting design goals. Modern design requires the best of both worlds: reduced engine emissions and fuel consumption with more power, reduced weight and vibrations, optimal sound and maintenance-free operation. LMS Virtual.Lab Powertrain Motion is a complete, integrated solution to simulate complex dynamic engine performance and accurately predict internal loads. Loads are required to determine fatigue life, vibrations and engine radiated noise. Using virtual simulation, engineers can quickly identify the most promising new engine concepts and ideas, such as cam phasers, variable valve-lift devices and variable compression-ratio engines. LMS Virtual.Lab Powertrain Motion also supports engineers investigating shaft whirl, torsion vibrations, chain noise, gear rattle and whine to optimize driveline system dynamics. LMS Virtual.Lab Powertrain Motion provides dedicated powertrain modeling templates that help users to quickly build detailed models of full powertrain assemblies or specific sub-assemblies like valve train, crank train, driveline, timing chain and belt, geartrain and other accessory drives. Separately created sub-mechanisms can easily be joined together to study coupled behavior. The powertrain template generates fully parameterized models enabling fast modifications and accelerated alternative design analysis. The LMS Virtual.Lab Motion solver handles a broad range of powertrain applications directly on the virtual model: • Valve train: simulate high-order/ high-speed effects including spring surge, cam-contact design, or valve-seating performance • Crank train: analyze crankshaft and engine block interactions, bearing loads, crankshaft vibrations and dynamic stress • Driveline: analyze prop shaft bending and whirl, garage clunk and shift clunk, or driveline booming • Timing chain: quick lay-out and fast recursive solver for dynamic simulation of complicated sprocket, guide, tensioner and chain configurations Features • Modeling elements for hydrodynamic bearings, flexible valve springs, cam contact forces, hydraulic lash adjuster • Combustion tacho elements apply measured gas forces to pistons and cylinder head • Cam profile synthesis tool • Automatic set-up of valve train parts, gas forces and firing order adapted to engine configuration • Integrated engine-speed controls for simulation of stationary speeds, speed sweeps and transient run-ups • Flexible bodies support dynamic stress computation • Dynamic stress animations indicate failure • Topological hot spot detection ranks the most stressed regions on the FE mesh Benefits • Templates accelerate crank train, valve train and timing drive systems modeling • Predict loads throughout the powertrain system • Evaluate dynamic stress on different engine regimes to efficiently determine engine vibrations and analyze crankshaft and engine block reliability • Study new engine concepts, such as cam phasers, variable valve-lift devices and variable compression-ratio engines • Design powertrain components while respecting dynamic performance targets • Study belt and chain dynamics and coupled powertrain subsystem behavior Software engineering memiliki misi menyediakan quality engineering software untuk para engineer sehingga mereka dapat lebih produktif dalam pekerjaannya.
