Analysis of vehicle behavior under crosswind using air spring pressure

To clarify the behavior of railway vehicles under crosswind, a new method using left-right balance air spring pressure is presented in this paper. The rate off-loading, which an evaluation index for vehicle behavior, can always be estimated by without conventional special wheel-set. theoretically derived and accuracy experimentally verified comparing with method. In experiment, lateral forces equivalent to crosswind were loaded statically or dynamically, running test was conducted. results show that are good agreement useful when analyzing crosswind. By applying practical Shinkansen, it possible obtain statistical data on at higher speeds wind easily than methods. Much analyzed relationship between speed validity Kunieda’s equation used design verified. This monitor effects not only specific points but also along lines. Therefore, identify areas where likely affected strong winds. Some examples further improve safety against winds shown
