| Abstract: | A portable bilateral wheel-rail profilometer is investigated and designed,to provide authentic data for the investigation of wheel-rail interface geometry.The design of mechanism and the mathematic model are proposed.Contrary to measured objects,namely wheelset and rail,the parameters of five-bar mechanism are simulated for optimization to satisfy measuring range and precision. The sampling procedure of encoder is simulated.The error of measurement model is calculated. |
