Catania Ricerche - IRC-Project Proposal
The project aims to identify, analyze and verify experimentally a set of technological solutions for saving energy and increasing energy efficiency in industrial and service.
The industrial sector in Italy alone accounts for 30% of energy and is therefore evident that propose interventions that could potentially generate savings and increase efficiency in production units will contribute significantly to the achievement of objectives adopted by the national and Community policies.
The project will generate in the first part of the design tools and methodologies to achieve efficient and compatible devices from an environmental point of view, in the second part design and / or execution of an automation systems (prototype manipulators) can reduce consumption and increase performance compared to similar devices currently available that can verify the real effectiveness from the point of view of energy saving.
The choice of systems has been to propose measures on the main constituent elements of automation devices on or actuators, transmission, control, structure, sensors. These prototypes have potential application almost immediate, because it takes into account the problem of the industrial prototype.
Description of proposal:
The objectives concern the design tools and methodologies to achieve efficient and compatible devices from an environmental point of view:
• Criteria for eco-design;
• Control Strategies efficient in terms of energy;
• Structural aimed at energy efficiency, such as topological design and optimization;
• integrated design environment.
Then you go to the design and implementation of a device where you can check the real effectiveness from the point of view of energy saving through the use of energy-saving techniques for parallel kinematics manipulators with high performance dynamics for industrial applications.
The architecture of a parallel robot must be designed for a more efficient in terms of energy. The cheap engines to chassis, as happens in most cases, involves moveable very light in materials performance and often recyclable as aluminium, carbon fibres or polymeric resins addition, a mobile light allows high speed and a reduction of couples drive, which are reflected in a reduction in the size and consumption of engines.
The increased structural rigidity compared to a serial enables high accuracy in processing because of minor vibration and deformation, which is reflected in often the elimination of further finishing operations. The specific objective is to study a Hexapod robot parallel of the 6 degrees of freedom for industrial applications at high speed. The Hexapod consists of a mobile platform which is applied to the end effector, and six legs that run on six prismatic guides mounted on a frame that acts as a fixed platform
In addition, the robot will be designed and intended for savings and increased efficiency in energy utilization phases considering aspects optimization of the statics-dynamics, path planning, the optimal sizing of the links of the structure, the economic choice of materials, light and the choice of engines and control systems with low consumption and high efficiency.
The activities will be divided as follows:
• State of the techniques and strategies in order to save energy applied to parallel kinematics manipulators working in the industry at high speed;
• Proposal for a new Hexapod legs with a constant length based on the principles of design robust global and local;
• Study of kinematics, singularity and working space;
• Analysis of structural and mechanical vibration;
• Study of the dynamic model and dynamic optimization to energy saving manipulator of the same during his movement;
• Choice of system implementation with electric motors and high-efficiency variable speed regulators for path planning or pneumatic actuators for high performance applications like point-to-point;
• Creation of a prototype scale;
• Experimentation and illustration of the results;
At the end of the program will be available a series of effective design tools and a set of devices used in industry. Specifically regarding the prototype will be given special attention to design choices because it is possible inclusion in the same production lines and are reasonably close to industrial devices.
