Noliac develops robust piezoelectric actuators
A
Noliac product story
Edited by the Engineeringtalk editorial team
Sep 19, 2008
Noliac is developing a range of piezoelectric actuators that will resist humidity, have fewer cracks in the ceramic material and will last longer.
They will be used in applications such as: noise and vibration damping for wind mill turbines, control systems in automobiles, wire bonding and active wheel suspension and engine mounts in cars.
Car weight has almost doubled in the past few decades as manufacturers compete to install noise and vibration damping materials that grant better comfort and security.
Many consumers haven't noticed the weight increase because engines have become more effective, leaving petrol consumption unchanged or lower.
Active mounting based upon piezoelectric actuators will make it possible to reduce noise and vibrations in automobiles without weight increase.
The active mounting imposes contra vibrations, neutralising the vibrations from engines.
Noliac are cooperating with three universities and German car manufacturers Contitech and Ricardo to develop active mounting.
They will also cooperate with product development experts at Noliac Ceramics in the Czech Republic and IPU in Denmark.
Noliac came up with the idea in 2006 and forwarded a project description to the European Commission's research programme FP7.
The European Commission has given EUR6m to the project and the project participants will raise another EUR2m.
The project will last four years.
