1. A Friction Model for Laminator Nips
University essay from Lunds universitet/Institutionen för reglerteknikAbstract : The main objective for the thesis project is to find a suitable mathematical model of the velocity dependent friction force that arises between the nip roller and the carton material in the laminator at slip, in order to enable realistic simulations of the nip in the laminator. Theoretically, the LuGre model is found to contain the necessary physical properties for the actual situation. READ MORE

2. Online Identification of Friction Coefficients in an Industrial Robot
University essay from Institutionen för systemteknikAbstract : All mechanical systems with moving parts are affected by friction, including industrial robots. Being able to design an accurate friction model would further increase the performance of todays robots. Friction is a complex dynamic phenomena that is constantly changing depending on the state and environment of the robot. READ MORE
