LMS Imagine.Lab Lubrication offers the required tools to model and design the entire engine lubrication system with all the associated components (pump, valves, bearings) for performance validation, system optimization, failures investigation and evaluation of new architecture.

With LMS Imagine.Lab Lubrication, users can perform steady-state and transient analyses, as well as isothermal or thermal analyses.

The complete oil path through the engine model can be used to make sure that the required amount of oil is delivered to the different components. The aim is to optimize pump sizing, to develop intelligent systems (piloted pump) thereby reducing power absorbed by these components as well as systems using oil pressure (VVT, VVA and more). In this way, the integration of new components (oil cooler, VVT, VVA, piston cooling jets) can be evaluated. A total synchronization of components (pump) for different engines and platforms can thus be achieved as well as a detailed validation of production-driven architecture changes.

LMS Imagine.Lab Lubrication is able to run steady-state and transient analyses which take thermal effects into account. The user can integrate frictional heat sources in pumps, bearings and contacts between piston rings and cylinder liner to evaluate the oil temperature increase during warm-up. Moreover, it is possible to assess the thermal interactions between components and develop related heat management strategies for oil cooler and piston cooling jets, for example.

Dynamic analysis can also be performed by studying component and pressure dynamics. Especially for hydraulic components, line models and the hydraulic component design concept, the solution helps to assess pressure pulsations resulting from inertia effects in rotating parts (connecting rod supply) as well as the performance of fluid power systems using oil pressure from lubrication circuits (VVT, HLA, chain tensioner).

Messier-Bugatti optimized the A380 nosewheel steering and braking system with LMS Imagine.Lab AMESim

To save weight on the A380 superjumbo aircraft, Messier-Bugatti used LMS Imagine.Lab AMESim and the Ground Loads solution to design an innovative decentralized hydraulic generation system with lightweight micro-pumps delivering power locally to emergency braking and landing gear steering systems.

Renault applies AMESim to streamline its cooling and air-conditioning systems development process

To comply with the multiple constraints relative to vehicle designs that affect the thermal management of underhood systems, and to ensure high-quality passenger comfort, Renault decided to rely more on simulation to engineer the underhood thermal environment. The French car maker deployed the AMESim solution as a collaborative system simulation platform.
