A. What is hydraulic simulation?
What is hydraulic?
Hydraulic deals with low compressible fluids. Thermal aspects can be considered.
Hydraulic systems as well as Hydraulic components.
Hydraulic applications:
- Engine industry
- Aerospace
- Hydraulic power
- Hydraulic components design: turbomachines, pumps…
What is simulation?
- The simulation model is an assembly of hydraulic components
- Description of physical phenomena based on few “macroscopic” parameters
- Multi-domain / Multi-level approach
- Hydraulic Components are described with analytical or tabulated models
- Simulation results for hydraulic systems deal with static/dynamic responses (time & frequency domains)
The Hydraulic simulation enables to design complete hydraulic systems, thanks to physical-based simulation, from the sources (tank) to the consumers (actuators, etc.) through a hydraulic network.
The main issues that can be solved by using hydraulic simulation are:
- Optimize hydraulic systems architectures & Fast dynamics behaviors through simulation
- Develop accurate control strategies connected to associated sub-systems (magnetic, piezoelectric, …)
- Handle more flexibility linked to hydraulic systems performances
- Manage thermal constraints on hydraulic systems
- Share and capitalize high level of knowledge on hydraulics to transmit the know-how with simulation models
Examples of hydraulic system simulation:
Common Rail injection system
- Purpose : Analysis and design of a Common Rail injection system
- Injection system for Diesel engine (pressure in range [1000-2000] [bar])
The whole hydraulic system is simulated:
- High pressure pump
- Pressure regulator
- Injectors
- Hydraulic network
Design of an injector
- Purpose : Design of an injector
- Detailed model of the injector with hydraulic and mechanical part
- In this case, the simulation of hydraulic and mechanical part allows to design the whole injector in detail
Swash plate pump
- Purpose : Design of a swash plate pump
- Detailed model of the pump with geometry of hydraulic and mechanical part
- In this case, the simulation of hydraulic and mechanical part allows to design the whole injector in detail
