Oil Thermal Management for Friction Reduction

This FREE half-day seminar presents capabilities for modeling lubrication systems, detailed pumps, bearings, and friction. New features of v2017 will also be discussed.

With the increasing demands on lowering emissions and fuel consumption the reduction of engine and transmission friction losses has become a key focus of the industry. Up until now the lubrication system has been affected by optimizations of the engine warmup behavior by means of changes to the combustion process and cooling system implicitly and the introduction of variable and electrical oil pumps explicitly. However additional potential lies in actively controlling the lube supply at moderate engine operating conditions which are common in many driving cycles. In those operating conditions oil temperature is usually lower and viscosity higher than at full load conditions causing increased friction.
This seminar will introduce you to the capabilities of using GT-SUITE for modeling lubrication systems, detailed pumps and friction that can be used to perform design studies on the complex interaction of those systems. This includes an introduction to
– Flexible new ways of modeling of lubrication systems from CAD
– Model management throughout the product design cycles
– Modeling of oil pumps including friction
– Modeling of bearings including using GT-SUITEs EHD bearing technology
– Short overview on new v2017 features for lubrication system modeling

Hydraulics for Engine and Transmission Systems

This FREE half-day seminar presents capabilities for hydraulic system and component modeling, with particular attention to powertrain applications. New features of v2017 will also be discussed.

With increasing customer demands on driver comfort and consumption as well as continuously stricter emission regulations, powertrains have become highly sophisticated and therefore complex systems. This includes integrating electrical, mechanical and hydraulic components. While the complexity increases, the product development cycles shrink. It is therefore key to understand and optimize the interactions of those systems early in the product development cycle in a streamlined process, as this helps to avoid the risk of cost-inefficient design iterations.

In order to address the needs of our customers, GT-SUITE is able to integrate engine performance models with those subsystems, in a time efficient manner. To emphasize this, the seminar will focus on the integration process of hydro-mechanical models with GT-SUITE engine performance models.

Demonstration examples will include the following:
– Diesel fuel injection system
– Hydraulic variable valve actuation/timing system
– Automatic transmission actuation
– Related topics proposed during registration can also be considered

The participant will be introduced to:
– GT-SUITE capabilities for modeling hydro-mechanical systems and components
– Integration of hydro-mechanical models with other subsystems (typically GT-SUITE engine performance models) for accuracy and optimized CPU times.
– New hydraulic features in v2017
