This two-day class will introduce engineers to modeling fuel injection and hydraulic components as well as complete hydraulic systems in GT-SUITE. This will include discussion of creating detailed, predictive models of components in which the fluid-mechanical interaction is important. Examples of the components to be discussed include pumps, pressure regulators, injectors and hydraulic networks. The training will consist primarily of interactive model building, but will also include demonstrations from the instructor and guided examination/analysis of pre-built models. Each student will be provided with a computer to use.
1. Modeling the flow network: build a model of the flow network by two methods. First, the participant will learn how to build flow components manually to understand basic modeling and discretization concepts. Second, a 3D CAD file will be quickly and easily transformed in to a 1D flow network model using the GT-SUITE pre-processor, GEM3D.
2. Modeling hydraulic and injection components: create detailed, predictive models of hydraulic components in which the fluid-mechanical interaction is important. Examples of the components to be discussed include high pressure pumps, pressure control valves, injectors, etc.
3. Modeling pumps: discussion of different levels of models as well as the different types of pumps. Pressure pulsation and flow ripple predictions will also be analyzed.
4. Modeling a hydraulic system: build a model of the full system. Various levels of detail for modeling the hydraulic components (pumps, valves, etc.) will be discussed, ranging from imposing the behavior to predicting it. Pressure waves in the system as well as thermal effects in a closed-loop circuit will be analyzed.
5. Integration of hydraulics with 2D and 3D multi-body dynamics (time permitting): link hydraulics to 2D and 3D mechanical components. Typical applications include detailed (2D) spring modeling, detailed dynamics of pumps, detailed cam shaft modeling, mobile hydraulic equipment, etc.
6. Integrating predictive injection and combustion (time permitting): integrate a predictive diesel injector model with an engine model employing predictive combustion. Multiple levels of predictive combustion modeling will be discussed.
7. General GT-SUITE topics: In addition to the above topics, this course will also discuss some of the general features in GT-SUITE, including:
· 1-D Flow (steady state and transient) simulation
· Solver options (explicit vs. implicit)
· Fluid properties
· Cavitation and aeration
· Model Setup- initialization, parameters sweeps, convergence
· Optimization and DOE
· Simulink co-simulation
· User-created compound templates
· User routines
