3 Dimensional Dynamic Interaction Analysis of Actively Controlled maglev guideway structures

초록

Three-dimensional dynamic interaction analyses for actively controlled maglev are presented. Dynamic governing equations of cabin and bogie are derived by combining the 25 degrees of freedom maglev vehicle model including vertical and horizontal displacement, pitching, rolling and yawing. The maglev vehicle model consists of one cabin and four bogies which consist of eight EMS, four sensors and four suspensions. In the present study, UTM01 controller is used for electromagnetic suspension, vertical and horizontal irregularity are artificially created from power spectral density (PSD) function proposed by FRA. Under the same condition, analyses are carried out for two-dimension model and three-dimension model to confirm feasibility for presented model. From the three-dimensional analysis with horizontal roughness, dynamic responses are obtained more accurate than former studies.
