Excellent start of passive damping training in precision engineering

Due to the great interest and need for knowledge about the influence of passive damping in precision technology, High Tech Institute and Mechatronics Academy are organizing a second extended edition of the new training Passive damping for high tech systems next autumn.

The first edition of the training Passive damping for high tech systems, last April, was fully booked. Participants came from high-tech OEMs, research institutes and first-tier suppliers, both from the Netherlands and from companies abroad. The brand new training was unanimously praised by the twelve participants, an very enthusiastic group with good interaction, said Hans Vermeulen.

The only minus was the somewhat short duration. Participants found two and a half days a little lean. They expressed the wish to add half a day to have more time to be able to work out a case. One of the participants even advised to extend the training to a full week. Trainers Kees Verbaan and Hans Vermeulen, guest speaker Stan van der Meulen and course leader Adrian Rankers have therefore decided to extend the coming edition that starts on November 19 by half a day. ‘That way we create more time for different exercises,’ says Rankers.

Anyway, the enthusiasm about the content and the trainers was shared by everyone. ‘Passive damping is part of the complex dynamic world. I can tell from now on I liked the diversity of the course’, one participant noted.

Various topics were mentioned as useful ingredients, such as ‘how to adjust the stiffness contribution of the damper’, ‘how to design a damper made of rubber’, ‘aspects in the different design steps’, ‘differences in narrow and broad band damping’, ‘how to model a system with passive damping’ and ‘how to select materials for passive damping’. One participant expressed his surprise: ‘Dampers made out of liquid, never thought about that!’ Another summarized: ‘Excellent training, very inspiring, I already have multiple ideas how to use passive damping in actual systems’.

Kees Verbaan says that the participants in last April’s edition were mainly from high-end companies that design systems with high demands on accuracy. Despite the big diversity in application areas, varying from stages and handlers to beam lines, most participants appeared to be somehow active in the field of dynamics, and wanted to understand the possibilities of damping for their particular area,’ said Verbaan.

Due to the diversity of the participants, each of them favored different topics. Modeling and optimization was experienced by some as extremely instructive, while others were more interested in rules of thumb and understanding of dampers. ‘This is not a math course,’ says Verbaan. ‘Because of the global approach to this topic, most of them were helped by the overview that was created by the combination of topics. As a result, the content fit for different people in different ways.’
