Abstract: A 1:5 scale railway roller rig, which is located in Manchester Metropolitan University, is studied. Similarity testing and similarity laws are discussed. Based on measuring the parameter of testing system, the testing system mathematical model are set up. Using numerical value analysis method, the bogie hunting motion are studied, and the relation similarity rate are given. The hunting test is carried out.

Key words: Bogie Roller rig, Railway vehicle, Similarity testing, surface planarity, translational movement, magnetorheological planarization
