Project Title: Improving Machining Productivity Using Inerters
Inerters first found use in Formula 1 racing, where they were given the codename ‘J-dampers’ and used to improve the McLaren team’s suspension. After the confidentiality agreement between McLaren and Cambridge expired, researchers have moved to adapt the technology- which is superficially similar to tuned mass damping, except with a huge reduction in mass and size- for other sectors, including civil engineering.
My current research is focused on combining one type of inerter, which uses fluid flow to produce inertia, with established magnetorheological valve designs to produce a semi-active, controllable inerter. The machining implications of this may include tuneable vibration isolation, improvements in chatter reduction or even robotic heavy machining.
