In order to simulate the lateral vibration of bogie car easily, both in quality and in quantity, a calculation method was studied using a linear model which considered the contact force between the wheel and rail. The calculation results were compared with the data of a Shinkansen electric car obtained in a test running on an artificially set lateral alignment track irregularity. As the result, it was made clear that the calculation did not coincide with the characteristics of real cars because of the large elasticity in truck turning. But by decreasing the elasticity and restricting the wheelset excursion in the play between the flange and rail, the calculation results became similar to the features of real cars. It was also confirmed that decreasing the lateral elasticity of the secondary spring was effective in reducing of lateral vibration.
