Magnetostrictive Actuators for Damage Analysis and Vibration Control

Ziel



Objectives and content

There is a strong demand in the European manufacturing industry for new actuators with smaller size and improved properties like more power, less weight, higher reliability, less power consumption, and compatibility with microelectronics. Especially in manufacturing industries, in tool machines, aircraft, cars and automation which were the strengths of European industry we are losing our position in the -markets with respect to companies from Japan and Asia. A new emerging area of great potential application for new and advanced actuators is the area of smart (or intelligent) structures, material and systems. Quite obviously, the broad scope of the potential applications that emerges from this new technologies cannot be addressed by only few actuators devices and different types have been proposed, like micro-actuators, piezoelectric, electro/magneto-rheological, electromagnetic, shape memory material and magnetostrictive.
Rare earth-iron magnetostricitve alloy are featured by "giant" strains when excited by a magnetic field. Therefore the target of this proposal is to address this particular or unique characteristic of the magnetostrictive material to accomplish the need in two specific and very important fields of application in which the demand of actuators with unusual performances in term of forces and frequency range is very strong. These field of application are:
- Detection and identification of damaged structures;
- Active control of vibration.

In the field of active vibration control and related field of active vibration isolation, very often strong limitation are reported due to narrow frequency bandwidths, complicated design or an inability to support static weight, of the conventional actuators. Vibration control in heavy duty application and high dynamics is missing. Same limitations have been reported or foreseen for the emerging and very promising field of damage detection and identification of the structures although this research area holds very strong importance for health monitoring of structures. Hence the whole of proposal topics covers the following areas: reliability and quality of materials and products, safety and reliability of production systems, technologies for vehicle safety, technologies for aircraft safety. The work-plan is finalised to design and construct some actuators prototypes. One type of actuator is not sufficient for several engineering applications because it is not easy to produce actuators with equal capability in a wide frequency and force range. Therefore the programme is addressed to design and achieve 4 light actuators for the applications in which low forces are requested and 2 heavy actuators for the applications which need high forces. In order to meet the project technical objectives the required principal tasks are outlined as follows:
- Requirement Definition for Magnetostrictive Actuators
- Material Choice
- Design and Numerical Simulation
- Construction of Light Actuator Prototypes
- Construction of Heavy Actuator Prototypes
- Signal Processing and Control
- Utilisation of Magnetostrictive Actuators and Sensors in Engineering Problems.

Hence organisation of work-packages is addressed to define the design guidelines and to achieve prototypes of enhanced magnetostrictive actuators for the engineering application above mentioned.
