Abstract
A rolling guideway has mechanical contact surfaces between rail and carriage on rolling elements, which causes friction. As the change of friction force affects the motion accuracy, knowledge of friction force is important. In this research, the friction force is analyzed by measurement of an experimental rolling guideway and simulation with locomotive multi-bristle model. The change of friction force with and without grease lubrication is simulated by using the numerical parameters identified by measurement. Comparing the results, an effect caused by grease lubrication on friction force is observed.
