New Software Generation for Greener Energy Efficient Mechatronic System Design & Analysis
V. Remillard(빈센트 레밀라흐드),J. Sfeir,C. Quennouelle,D. Lenoble,J. S. Lee(이정수) 유공압건설기계학회 2013 유공압건설기계학회 학술대회논문집 Vol.2013 No.6
In the world of simulation software, many different approaches are used to obtain accurate hydraulic circuit simulation. Most of these tools model components as a set of mathematical equations parameterized with mechanical and geometric data for each component. They are able to simulate in depth specific functions of a circuit, however it becomes progressively a more demanding task to simulate more complex and complete systems. One of the key elements of simulation software is its ability to model valve performance in terms of flow characteristics, pressure drop and flow force. This also holds true for pumps and motors where the knowledge of efficiencies is required to achieve realistic duty cycle behavior. In this paper, the chosen approach is to demonstrate the efficiency of modeling components using a software downstream design methodology by implementing readily available performance curves and other characteristics of hydraulic components and functions. This downstream method of modeling components ensures the reliability and accuracy of systems behavior based on manufacturer specific data and allows for fast simulation of complete virtual machines which is impractical to achieve by traditional upstream programming. The simulation of a complete hydraulic system delivers global validation and analysis capabilities that can also be exploited beyond the engineering design scope including maintenance diagnostics and training activities. This paper will demonstrate that using Automation Studio™ ?a commercially available off-the-shelf drawing and simulation software tool that uses mainly downstream design? simulation data and OEM product information can be easily entered from a readily available hydraulic component vendor in order to create valves, pumps and motors for fast and accurate sizing and system simulation of a virtual machine. The ability to realistically simulate entire machines offers a unique capability to monitor, and study specific performance criteria such as: hysteresis, pressure drop, leakage, flow force, and other flow/pressure characteristics, power generation and transmission up to the full energy consumption at various operating conditions.

A Combination of Traditional Control and Hybrid Modeling Methods for Intelligent Fluid Power Systems
Veronique Bader,V. Remillard,D. Lenoble 유공압건설기계학회 2015 유공압건설기계학회 학술대회논문집 Vol.2015 No.10
The necessity for greener and more efficient equipment has led OEMs and manufacturers to bring intelligence into fluid power systems. The integration of electronic controls in key components allow for better power management and safer work environment, which are two major concerns in the fluid power industry. One of the challenges of these new integrated solutions resides in the complexity of the design which involves many different expertise. Fluid Power, Electrical and Control Specialists need a communication platform to develop more efficient systems combining all technologies. Traditional control modeling methods are used to develop performant controllers with the help of equation-based or model-based software. However, more hybrid modeling methods – such as Machine Knowledge Management – are favored to design fluid power systems using integrated mechatronics software. By combining both methods to allow integration or co-simulation, control specialists will be properly integrated in the design and analysis process to build more intelligent machines.
